Resource Aggregator for ODIM

Resource Aggregator for Open Distributed Infrastructure Management (Resource Aggregator for ODIM™) is a modular, open framework for simplified management and orchestration of distributed physical infrastructure.

Resource Aggregator for ODIM comprises the following two key components:

The resource aggregation function:

The resource aggregation function is the single point of contact between the northbound clients and the southbound infrastructure. Its primary function is to build and maintain a central resource inventory. It exposes Redfish-compliant APIs to allow northbound infrastructure management systems to:
- Get a unified view of the southbound compute, local storage, and Ethernet switch fabrics available in the resource inventory
- Gather crucial configuration information about southbound resources
- Manipulate groups of resources in a single action
- Listen to similar events from multiple southbound resources
One or more plugins:

The plugins abstract, translate, and expose southbound resource information to the Resource Aggregator through RESTful APIs. Resource Aggregator for ODIM supports:
- Generic Redfish plugin for ODIM (GRF plugin): This plugin can be used for any Redfish-compliant device
- Dell plugin for ODIM: Plugin for managing Dell servers
- Lenovo plugin: Plugin for managing Lenovo servers
- Cisco ACI plugin: Plugin for managing Cisco ACI servers
- Plugin for unmanaged racks (URP): This plugin acts as a resource manager for unmanaged racks
- Integration of additional third-party plugins
Resource Aggregator for ODIM allows third parties to easily develop and integrate their plugins into its framework. For more information, see Resource Aggregator for Open Distributed Infrastructure Management™ Plugin Developer's Guide.

Resource Aggregator for ODIM deployment requirements

Deploying Resource Aggregator for ODIM in a data center involves installing the following microservices on one or more machines:

Kubernetes microservices
Resource aggregator microservices
- API
- Account-session
- Aggregation
- Events
- Fabrics
- Managers
- Systems
- Tasks
- Update
- Telemetry
- License
Plugin microservices such as the Dell plugin, Lenovo plugin, URP, and additional third-party plugins
Third-party services such as Kafka, etcd, Zookeeper, and Redis

These microservices can be deployed as portable, light-weight Docker containers. The containerized services are orchestrated and managed by Kubernetes—an open-source container orchestration platform that helps to automate, scale, and manage a containerized application. For more information on Kubernetes and its architecture, see https://kubernetes.io/docs/home/.

The following diagram illustrates how Resource Aggregator for ODIM is deployed and used in a Kubernetes environment. It indicates a cluster with three controller nodes (Node 1, Node 2 and Node 3) and any additional worker nodes can be added into the cluster.

To deploy Resource Aggregator for ODIM, you will require:

One virtual machine (VM) or a physical machine called the deployment node to deploy Kubernetes and Resource Aggregator for ODIM microservices. You can deploy the Resource Aggregator for ODIM microservices using the odim-controller command-line utility and use commands to:
- Set up the Docker environment
- Set up a Kubernetes cluster
- Deploy the containerized Resource Aggregator for ODIM microservices and third-party services on the Kubernetes cluster nodes
- Manage the Resource Aggregator for ODIM deployment
One or more physical or virtual machines called cluster nodes where the containerized Resource Aggregator for ODIM microservices and third-party services are deployed as pods. The cluster nodes include controller and additional worker nodes to share the extra load. The controller node in a cluster also functions as a worker node. A cluster can have either one or three controller nodes. A cluster with three controller nodes provides a high availability environment. In addition, you can add worker nodes into the cluster to scale up the resources and the services.

Each controller node has the following components:
- An underlying Ubuntu OS platform
- The containerd container engine
- The Resource Aggregator and the plugin microservice pods
- The infrastructure pods containing all the third-party services
- Kubelet, Kubeproxy, and the Kubernetes control plane comprising the API server, Scheduler, and the Controller-Manager
For more information on these Kubernetes components, see https://kubernetes.io/docs/concepts/overview/components/

The following diagram is a logical representation of each controller node in a Kubernetes cluster.

For one-node deployment, the northbound management and orchestration systems access the Resource Aggregator for ODIM services through the controller IP address. Communication between Resource Aggregator for ODIM and the southbound infrastructure happens through the same controller IP address.

For three-node deployment, the northbound management and orchestration systems access the Resource Aggregator for ODIM services through a virtual IP address (VIP) configured on the Kubernetes cluster using Keepalived. Communication between Resource Aggregator for ODIM and the southbound infrastructure happens through the same VIP.

Nginx acts as a reverse-proxy for the cluster nodes. Keepalived and Nginx together help in implementing high availability of the Resource Aggregator for ODIM services on the cluster nodes for both northbound management applications and southbound infrastructure.

Deployment guidelines

Consider the following guidelines while deploying Resource Aggregator for ODIM:

A deployment node is required to deploy Kubernetes and Resource Aggregator for ODIM microservices.
The following two deployment configurations are supported:
- One-node cluster configuration This configuration has only one cluster node that also functions as a worker node. It does not support scaling of the Resource Aggregator for ODIM resources and services. This implies you cannot add worker nodes in a one-node cluster.
- Three-node cluster configuration This configuration has three cluster nodes that also function as worker nodes for sharing the extra load. It provides high availability environment by allowing the scaling of the Resource Aggregator for ODIM resources and services. This implies you can add worker nodes and increase the number of service instances running in a three-node cluster.
To convert an existing one-node cluster into a three-node cluster, you must reset the one-node deployment first, and then modify the required parameters in the odim-controller configuration file.

NOTE: Resetting the existing deployment clears all data related to it.
Do not remove the controller nodes of a Kubernetes cluster.
The GRF plugin is not meant for use in a production environment. Use it as reference while developing third-party plugins.
Scaling of the third-party services—Kafka and Redis clusters is not supported.
At least one instance of a Resource Aggregator service and a plugin service is running in the cluster. The maximum number of instances of a Resource Aggregator service and a plugin service that are allowed to run in a cluster is 10.

```
Update the line “#$nrconf{restart} = 'i';” to the following content:
```
$nrconf{restart} = 'l';
```

Pulling Docker images of all Kubernetes microservices

On the deployment node, pull the Docker images of all the Kubernetes microservices:

docker pull <imagename>:<version>

Example: docker pull quay.io/calico/cni:v3.23.3

The following table lists the Docker images of all the Kubernetes microservices.

Docker image name	Version	Docker image file name
registry.k8s.io/kube-apiserver	v1.24.6	registry.k8s.io_kube-apiserver.tar
registry.k8s.io/kube-controller-manager	v1.24.6	registry.k8s.io_kube-controller-manager.tar
registry.k8s.io/kube-proxy	v1.24.6	registry.k8s.io_kube-proxy.tar

registry.k8s.io/coredns/coredns	v1.8.6	registry.k8s.io_coredns_coredns.tar
registry.k8s.io/cpa/cluster-proportional-autoscaler-amd64	1.8.5	registry.k8s.io_cpa_cluster-proportional-autoscaler-amd64.tar

Verify you have successfully pulled all the images.
```
docker images
```
You get an output similar to the following sample:
Save each Docker image to a tar archive:
```
docker save -o <Docker image file name> <Docker image name>
```
Example: docker save -o quay.io_calico_node.tar quay.io/calico/node
Copy each saved tar archive to a directory called kubernetes_images on the deployment node.

Example: cp /home/<user>/*.tar /home/<user>/kubernetes_images

IMPORTANT: When deploying Resource Aggregator for ODIM, update the kubernetesImagePath parameter in kube_deploy_nodes.yaml file with the path of the kubernetes_images directory you choose in this step. The images are automatically installed on all cluster nodes after deployment.

The kube_deploy_nodes.yaml file is the configuration file used by odim-controller to set up a Kubernetes cluster and to deploy the Resource Aggregator for ODIM services.

NOTE: Verify the permissions of the archived tar files of the Docker images; the privilege of all files must be user:docker.

Building Docker images of all Resource Aggregator for ODIM services

Run the following commands on the deployment node:

```
cd /home/${USER}
```

git clone https://github.com/ODIM-Project/ODIM.git

```
cd ODIM
```
```
 export ODIMRA_USER_ID=2021
```
```
 export ODIMRA_GROUP_ID=2021
```
```
 ./build_images.sh
```

  sudo docker images

If the images are built successfully, you get an output similar to the following sample:

Pull the reloader and busybox images:

docker pull stakater/reloader:v0.0.76

docker pull busybox:1.33

Save the Docker images of all Resource Aggregator for ODIM services to a tar archive.

docker save -o <image_name.tar> <image_name>:<version>

Example: docker save -o api.tar api:7.0

The following table lists the Docker images of all Resource Aggregator for ODIM services:

Docker image name	Version	Docker image bundle name
account-session	5.0	account-session.tar
aggregation	6.0	aggregation.tar
api	7.0	api.tar
events	7.0	events.tar
fabrics	5.0	fabrics.tar
managers	7.0	managers.tar
systems	7.0	systems.tar
licenses	4.0	licenses.tar
task	6.0	task.tar
update	6.0	update.tar
kafka	3.0	kafka.tar
zookeeper	3.0	zookeeper.tar
etcd	1.16	etcd.tar
redis	5.0	redis.tar
stakater/reloader	v0.0.76	stakater_reloader.tar
busybox	1.33	busybox.tar
dellplugin	3.1	dellplugin.tar

urplugin	3.4	urplugin.tar
grfplugin	4.1	grfplugin.tar
aciplugin	3.3	aciplugin.tar
telemetry	4.0	telemetry.tar

To install the Docker images of all services on the cluster nodes, create a directory called odimra_images on the deployment node and copy each tar archive to this directory. For example: cp /home/<user>/ODIM/*.tar /home/<user>/odimra_images

IMPORTANT: While deploying ODIMRA, update the odimraImagePath parameter in kube_deploy_nodes.yaml file with the path of the odimra_images directory you choose in this step. The images are automatically installed on all cluster nodes after deployment.

NOTE: The kube_deploy_nodes.yaml file is the configuration file used by odim-controller to set up a Kubernetes cluster and to deploy the Resource Aggregator for ODIM services.

Updating additional package versions

While deploying Resource Aggregator for ODIM, verify the versions of the following packages and update them if required:

linux-headers
Keepalived
Nginx

NOTE: Verify the Keepalived and Nginx package versions only in case of a three-node cluster deployment.

linux-headers

Enter the following command:
```
sudo apt-cache madison linux-headers-6.2.0-26-generic
```
NOTE: If the above command fails with the error message, N: Unable to locate package linuxheaders-6.2.0-26-generic, the package version has been updated. Proceed with further steps to find the latest version.

Enter the following command:

sudo apt-cache search --names-only "linux-headers-[0-9.-]*-generic" | tail -5 | sort -r

Verify if the first entry in the output list is present in the cache.
```
sudo apt-cache madison <package_name>
```
Example for <package_name> is linux-headers-6.2.0-26-generic
In case of a version mismatch, update the latest version of linux-header package in:

~/ODIM/odim-controller/odimra/group_vars/all/requirements.yaml

Keepalived

Enter the following command:
```
sudo apt-cache madison keepalived
```
Verify if the latest version is keepalived=1:2.2.4-0.2build1.
In case of a version mismatch, update the latest version of the Keepalived package in:
```
~/ODIM/odim-controller/odimra/group_vars/all/requirements.yaml
```

Nginx

Enter the following command:
```
sudo apt-cache madison nginx
```
Verify if the latest version is nginx=1.18.0-6ubuntu14.4.
In case of a version mismatch, update the latest version of the Nginx package in:
```
~/ODIM/odim-controller/odimra/group_vars/all/requirements.yaml
```

Generating encrypted passwords for nodes and Redis

Encrypting passwords of the local non-root user on the Kubernetes cluster nodes and Redis database makes the deployment process non-interactive. If the encrypted password is not available during deployment, you are prompted to enter the password for the first time.

Resource Aggregator for ODIM uses the odim-vault tool to encrypt and decrypt passwords.

On the deployment node, navigate to ~/ODIM/odim-controller/scripts.
```
cd ~/ODIM/odim-controller/scripts
```

Build the odim-vault tool.

go build -ldflags "-s -w" -o odim-vault odim-vault.go

Enter a random string in a file called odimVaultKeyFile and save it.
```
vi odimVaultKeyFile
```
The entered string acts as the odim-vault crypto key. It is required for encrypting and decrypting the local user password of the Kubernetes cluster nodes.

NOTE: Do not add special characters in the string.
Encode the entered odim-vault crypto key:
```
./odim-vault -encode ~/ODIM/odim-controller/\
scripts/odimVaultKeyFile
```
Result: odimVaultKeyFile contains the encoded odim-vault primary key.

Change the file permissions of odimVaultKeyFile.

chmod 0400 /home/${USER}/ODIM/odim-controller/\
scripts/odimVaultKeyFile

Enter the password of the default non-root user (that you set across all cluster nodes initially) in plain text in a file called nodePasswordFile.
```
vi nodePasswordFile
```
Save the file.

Encrypt the password:

./odim-vault -key ~/ODIM/odim-controller/\
scripts/odimVaultKeyFile -encrypt /home/${USER}/ODIM/odim-controller/\
scripts/nodePasswordFile

Result: nodePasswordFile contains the encrypted node password.

Change the file permissions of nodePasswordFile.

chmod 0400 /home/${USER}/ODIM/odim-controller/\
scripts/nodePasswordFile

Enter the password of the Redis in-memory database in plain text in a file called redisInMemoryPasswordFile.

vi redisInMemoryPasswordFile

Save the file.

Encrypt the password:

./odim-vault -key ~/ODIM/odim-controller/\
scripts/odimVaultKeyFile -encrypt /home/${USER}/ODIM/odim-controller/\
scripts/redisInMemoryPasswordFile

Result: redisInMemoryPasswordFile contains the encrypted node password.

Change the file permissions of redisInMemoryPasswordFile.

chmod 0400 /home/${USER}/ODIM/odim-controller/\
scripts/redisInMemoryPasswordFile

Enter the password of the Redis on-disk database in plain text in a file called redisOnDiskPasswordFile.
```
vi redisOnDiskPasswordFile
```
Save the file.

Encrypt the password:

./odim-vault -key ~/ODIM/odim-controller/\
scripts/odimVaultKeyFile -encrypt /home/${USER}/ODIM/odim-controller/\
scripts/redisOnDiskPasswordFile

Result: redisOnDiskPasswordFile contains the encrypted node password.

Change the file permissions of redisOnDiskPasswordFile.

chmod 0400 /home/${USER}/ODIM/odim-controller/\
scripts/redisOnDiskPasswordFile

Configuring log path for odim-controller

You can provide a desired file path for the odim-controller logs by setting ODIM_CONTROLLER_LOG_PATH environment variable. Upon the execution of odim-controller, the log file is stored as {ODIM_CONTROLLER_LOG_PATH}/odim-controller.log.

If the environment variable is not set, the log file is stored in the current directory where odim-controller was executed.

Upon each execution of odim-controller, the following information is logged:

Start time and end time of the execution
User and the groups, user belongs to
Options passed to odim-controller
Complete output of the operation

Deploying Resource Aggregator for ODIM and the Plugins

Topics covered in this section include:

Deploying the Resource Aggregator services
Deploying the Unmanaged Rack Plugin
Deploying the Dell plugin
Deploying the Cisco ACI plugin
Adding a plugin into the Resource Aggregator for ODIM framework

Deploying the Resource Aggregator services

Prerequisites: Ensure all the pre-deployment operations are complete.

Update the odim-controller configuration file:

Navigate to ~/ODIM/odim-controller/scripts on the deployment node.
```
cd ~/ODIM/odim-controller/scripts
```
Copy content from the kube_deploy_nodes.yaml.tmpl file to the kube_deploy_nodes.yaml file:
```
cp kube_deploy_nodes.yaml.tmpl kube_deploy_nodes.yaml
```

Edit the kube_deploy_nodes.yaml file.

vi kube_deploy_nodes.yaml

The kube_deploy_nodes.yaml file is the configuration file used by odim-controller to set up a Kubernetes cluster and to deploy the Resource Aggregator for ODIM services.

IMPORTANT: Do not change the format of the content in this file. Doing so might interrupt the Resource Aggregator for ODIM deployment process.

When you open the kube_deploy_nodes.yaml file for the first time, it looks like the following (for a three node cluster):

  Example output:
Deploy the Resource Aggregator services:
1. Log in to the deployment node and run the following command:
```
python3 odim-controller.py --deploy \
odimra --config /home/${USER}/ODIM/odim-controller/\
scripts/kube_deploy_nodes.yaml
```
  All the Resource Aggregator services and the third-party services are successfully deployed.
2. Log in to each cluster node, run the following command on each cluster node to verify all deployed services are running successfully.
```
kubectl get pods -n odim -o wide
```
  Example output:
  
  If the services are not successfully deployed, reset the deployment and try deploying again:
```
 python3 odim-controller.py --reset odimra --config \
 /home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
 --ignore-errors
```
  For a three-node cluster deployment, resetting deployment removes the virtual IP configured through Keepalived. After resetting the deployment, restart the Keepalived service. Also, ensure the parameters in the kube_deploy_nodes.yaml are not NULL. Update such parameters to "" or as per your requirement. For example: After resetting the deployment, update the odimCertsPath parameter to "" or to your actual certificate path in the kube_deploy_nodes.yaml file.
  
  NOTE: Save the RootServiceUUID in the kube_deploy_nodes.yaml file in the path ~/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml. If the services are not successfully deployed and you want to reset the deployment, you can use the saved RootServiceUUID.
Perform HTTP GET on /redfish/v1 using the following curl command on your deployment node.

IMPORTANT: Before running curl commands, unset http and https proxies, check if you have set proxy configuration. If yes, set "no_proxy" using the following commands:
```
unset https_proxy
```
```
unset http_proxy
```
```
export no_proxy="127.0.0.1,localhost,\
localhost.localdomain,10.96.0.0/12,\
<Comma-seperated_list_of_IP_addresses_of_the_deployment_node_and_the_cluster_nodes>"
```

Verify that all the Resource Aggregator services are listed in the JSON response body by running the following curl command:

curl -s --cacert \ 
{path_of_rootCA.crt} \ 
'https://{odim_host}:{port}/redfish/v1' -k

Replace {path_of_rootCA.crt} with the path specified for the odimCertsPath parameter in the kube_deploy_nodes.yaml file with <odimcertsPath>/rootCA.crt. The rootCA.crt file is required for secure SSL communication.

{odim_host} is the virtual IP address of the Kubernetes cluster.

NOTE: For a single node cluster configuration, {odim_host} is the ip address of primary node. For a three node cluster configuration, to use FQDN as {odim_host}, ensure that FQDN is configured to the virtual IP address in the /etc/hosts file or in the DNS server.

{port} is the API service port configured in Nginx. Default port is 30080. If you have changed the default port in the kube_deploy_nodes.yaml file, use that as the port.

The following JSON response is returned:

Deploying the Cisco ACI plugin

Refer to the deployment instructions of the Cisco ACI plugin here.

Adding a plugin into the Resource Aggregator for ODIM framework

After a plugin is successfully deployed, you must add the plugin into the Resource Aggregator for ODIM framework to access the plugin service.

Prerequisites

The plugin you want to add is successfully deployed.

To add a plugin, perform HTTP POST on the following URI:

https://{odim_host}:{port}/redfish/v1/AggregationService/AggregationSources

{odim_host} is the virtual IP address of the Kubernetes cluster. For one-node odim deployment, odim_host is the IP address of the cluster node.
{port} is the API service port configured in Nginx. Default port is 30080. If you have changed the default port in kube_deploy_nodes.yaml file, use that as the port.

The following ports (except container ports) must be free:

Port name	Ports
Container ports (access restricted only to the Kubernetes cluster network)	30080 — API service port 45101- 45201 — Resource Aggregator for ODIM service ports 9082, 9092 — Kafka ports 6379 — Redis port 26379 — Redis Sentinel port 2181 — Zookeeper port 2379, 2380 — etcd ports
API node port (for external access)	30080
Kafka node port (for external access)	30092 for a one-node cluster configuration. 30092, 30093, and 30094 for a three-node cluster configuration
GRF plugin port EventListenerNodePort lbport	45001 — Port to be used while adding GRF plugin 30081 — Port used for event subscriptions in one-node cluster configuration lbport — For three-node cluster configuration, specify lbport as per your requirement. This port must be assigned with a free port (preferably above 45000) available on all cluster nodes. This port is used as Nginx proxy port for the plugin For one-node cluster configuration, it is the same as EventListenerNodePort
UR plugin port	45007 — Port to be used while adding UR plugin
Dell plugin port EventListenerNodePort lbport	45005 — Port to be used while adding Dell plugin 30084 — Port used for event subscriptions in one-node cluster configuration lbport — For three-node cluster configuration, specify lbport as per your requirement. This port must be assigned with a free port (preferably above 45000) available on all cluster nodes. This port is used as Nginx proxy port for the plugin. For one-node cluster configuration, it is the same as EventListenerNodePort
Lenovo plugin port EventListenerNodePort lbport	45009 — Port to be used while adding Lenovo plugin 30089 — Port used for event subscriptions in one-node cluster configuration lbport — For three-node cluster configuration, specify lbport as per your requirement. This port must be assigned with a free port (preferably above 45000) available on all cluster nodes. This port is used as Nginx proxy port for the plugin. For one-node cluster configuration, it is the same as EventListenerNodePort

Request payload parameters

Parameter	Type	Description
HostName	String (required)	It is the plugin service name and the port specified in the Kubernetes environment. For default plugin ports, see Resource Aggregator for ODIM default ports.
UserName	String (required)	The plugin username. See default administrator account usernames of all the plugins in "Default plugin credentials".
Password	String (required)	The plugin password. See default administrator account passwords of all the plugins in "Default plugin credentials".
ConnectionMethod	Array (required)	Links to the connection methods that are used to communicate with this endpoint: `/redfish/v1/AggregationService/AggregationSources`. NOTE: Ensure that the connection method information for the plugin you want to add is updated in the odim-controller configuration file. To know which connection method to use, do the following: 1. Perform HTTP `GET` on: `/redfish/v1/AggregationService/ConnectionMethods`. You will receive a list of links to available connection methods. 2. Perform HTTP `GET` on each link. Check the value of the `ConnectionMethodVariant` property in the JSON response. It displays the details of a plugin. Choose a connection method having the details of the plugin of your choice. For available connection method variants, see the following "Connection method variants" table.

Plugin	Default username	Default password	Connection method variant
GRF plugin	admin	GRFPlug!n12$4	Compute:BasicAuth:GRF_v2.0.0
URP	admin	Plug!n12$4	Compute:BasicAuth:URP_v2.0.0

Use the following curl command to add the plugin:

curl -i POST \
   -H 'Authorization:Basic {base64_encoded_string_of_<odim_username:odim_password>}' \
   -H "Content-Type:application/json" \
   -d \
'{"HostName":"{plugin_host}:{port}",
  "UserName":"{plugin_userName}",
  "Password":"{plugin_password}", 
  "Links":{
      "ConnectionMethod": {
         "@odata.id": "/redfish/v1/AggregationService/ConnectionMethods/{ConnectionMethodId}"
      }
   }
}' \
 'https://{odim_host}:30080/redfish/v1/AggregationService/AggregationSources' -k

NOTE: To generate a base64 encoded string of {odim_username:odim_password}, run the following command:

echo -n '{odim_username}:{odim_password}' | base64 -w0

Default username is admin and default password is Od!m12$4. Replace {base64_encoded_string_of_[odim_username:odim_password]} with the generated base64 encoded string in the curl command. You will receive:

An HTTP 202 Accepted status code.
A link of the executed task. Performing a GET operation on this link displays the task monitor associated with this operation in the response header.

To know the status of this task, perform HTTP GET on the taskmon URI until the task is complete. If the plugin is added successfully, you will receive an HTTP 200 OK status code.

After the plugin is successfully added, it will also be available as a manager resource at:

/redfish/v1/Managers

For more information, see "Adding a plugin as an aggregation source" section in the Resource Aggregator for Open Distributed Infrastructure Management™ API Reference and User Guide.

To verify that the added plugin is active and running, do the following:
1. To get the list of all available managers, perform HTTP GET on:
  
  /redfish/v1/Managers
  
  You will receive JSON response having a collection of links to the manager resources. You will see the following links in the collection:
  - A link to the Resource Aggregator manager.
  - Links to all the added plugin managers.
2. To identify the plugin Id of the added plugin, perform HTTP GET on each manager link in the response.
  
  The JSON response body for a plugin manager has Name as the plugin name. Example: The JSON response body for the URP plugin manager has Name as URP.

Resource Aggregator for ODIM post-deployment operations

This section lists all the operations that you can perform after successfully deploying Resource Aggregator for ODIM. You can perform these operations to modify or upgrade the existing Kubernetes deployment.

NOTE: The operations listed in this section are not mandatory.

Scaling up the resources and services of Resource Aggregator for ODIM

Following are the two ways of scaling up the resources and services of Resource Aggregator for ODIM deployed in a Kubernetes cluster:

Horizontal scaling: It involves adding one or more worker nodes to the existing three-node cluster.

NOTE: Scaling of a one-node cluster is not supported—you cannot add nodes to a one-node cluster.
Vertical scaling: It involves creating multiple instances of the Resource Aggregator and plugin services.

NOTE: Scaling of third-party services is not supported.

Log in to each cluster node and update all the configuration files inside /opt/nginx/servers with the new node details.

NOTE: Refer the existing node entries and add the new node entry.
Update the kube_deploy_nodes.yaml file with the new node details being added.
To add a node, run the following command on the deployment node:
```
python3 odim-controller.py --addnode kubernetes --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml
```
Before adding a node, ensure that time on the node is same as the time on all the other existing nodes. To know how to set time sync, see Setting up time sync across nodes.

To scale up the Resource Aggregator services, run the following command on the deployment node:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--scale --svc <service_name> --replicas <replica_count>

Replace <service_name> with the name of the service which you want to scale up. To know all the complete list of supported deployment and service names, see Resource Aggregator for ODIM deployment names.

NOTE: You can scale up only the account-session, aggregation, api, events, fabrics, managers, systems, tasks, update, telemetryand all services. Replacing <service_name> with all will scale up all Resource Aggregator services.
Replace <replica_count> with an integer indicating the number of service instances to be added.

To scale up the plugin services, run the following command on the deployment node:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/\
kube_deploy_nodes.yaml --scale --plugin <plugin_name> --replicas <replica_count>

Replace <plugin_name> with the name of the plugin whose service you want to scale up. For example: urplugin, grfplugin, dellplugin, lenovoplugin, aciplugin
Replace <replica_count> with an integer indicating the number of plugin service instances to be added.

Scaling down the resources and services of Resource Aggregator for ODIM

Scaling down involves removing one or more worker nodes from an existing three-node cluster where the services of Resource Aggregator for ODIM are deployed.

NOTE: You cannot remove controller nodes in a cluster.

To remove a node, do the following:
1. Open the kube_deploy_nodes.yaml file on the deployment node.
2. Remove all the node entries under nodes except for the node that you want to remove.
3. Run the following command:
```
python3 odim-controller.py --rmnode kubernetes --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml
```

To scale down the Resource Aggregator services, run the following command on the deployment node:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--scale --svc <service_name> --replicas <replica_count>

Replace <service_name> with the name of the service which you want to scale up. To know all the complete list of supported deployment and service names, see Resource Aggregator for ODIM deployment names.

NOTE: You can scale down only the account-session, aggregation, api, events, fabrics, managers, systems, tasks, update, telemetryand all services. Replacing <service_name> with all will scale down all Resource Aggregator services.
Replace <replica_count> with an integer indicating the number of service instances to be removed.

To scale down the plugin services, run the following command on the deployment node:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--scale --plugin <plugin_name> --replicas <replica_count>

Replace <plugin_name> with the name of the plugin whose service you want to scale down. For example: urplugin, grfplugin, dellplugin, lenovoplugin, aciplugin
Replace <replica_count> with an integer indicating the number of plugin service instances to be removed.

Rolling back to an earlier deployment revision

Rolling back the deployment of Resource Aggregator for ODIM to a particular revision restores the configuration manifest of that version.

To list the revision history of the deployment of Resource Aggregator for ODIM, run the following command:
```
python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --list \
history --dep <deployment_name>
```
Replace <deployment_name> with the name of the deployment for which you want to list the revision history. To know all the supported deployment names, see Resource Aggregator for ODIM deployment names.

You will receive a list of revisions along with the revision numbers.

To roll back the deployment of Resource Aggregator for ODIM to a particular revision, run the following command:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --rollback \
--dep <deployment_name> --revision <revision_number>

Upgrading the Resource Aggregator for ODIM deployment

Upgrading the Resource Aggregator for ODIM deployment involves:

Updating the services of Resource Aggregator for ODIM to a new release.
Updating the configuration parameters of Resource Aggregator for ODIM.

NOTE: When you upgrade the Resource Aggregator for ODIM deployment, the new configuration manifests are saved by default.

To upgrade the Resource Aggregator deployments, run the following command:
```
python3 odim-controller.py --config /home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --upgrade <deployment_name>
```
Replace <deployment_name> with the name of the deployment which you want to upgrade. To know all the supported deployment names, see Resource Aggregator for ODIM deployment names.

To upgrade a plugin deployment, run the following command:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml
--upgrade plugin --plugin <plugin_name>

Replace <plugin_name> with the name of the plugin whose service you want to upgrade.

To update the odim-controller configuration parameters, do the following:
1. Navigate to ~/ODIM/odim-controller/scripts:
```

```

Backup and restore of Kubernetes etcd database

Identify the leader etcd node by running the following command on all the three cluster nodes:

ETCDCTL_API=3 sudo etcdctl endpoint status --write-out=table --endpoints=https://127.0.0.1:2379 --cacert=/etc/ssl/etcd/ssl/ca.pem  --cert=/etc/ssl/etcd/ssl/admin-{hostname}.pem  --key=/etc/ssl/etcd/ssl/admin-{hostname}-key.pem

NOTE: Replace {hostname} with the host name of the cluster node on which you run the command.

Verify the output on each node. The node with IS LEADER value as true is the leader node.
Create a backup directory on the leader node and change the ownership and permission of the directory to odimra:
```
mkdir ~/etcd_backup/
sudo chown odimra:odimra ~/etcd_backup/
sudo chmod 755 ~/etcd_backup/
```
Find the directory of the ca certificate and the node certificates by running the following command on leader node:
```
sudo grep ETCDCTL /etc/etcd.env
```
Copy all the ca certificate and node certificates to the backup directory as a root user:
```
sudo -i
cp /etc/ssl/etcd/ssl/* ~/etcd_backup/
```

Take the snapshot/backup of the etcd database by running the following command from the etcd leader node:

ETCDCTL_API=3  sudo etcdctl snapshot save ~/etcd_backup/etcd_backup.db \
 --endpoints=https://127.0.0.1:2379 \
 --cacert=~/etcd_backup/ca.pem \
 --cert=~/etcd_backup/ admin-{leader etcd nodename}.pem \
 --key=~/etcd_backup/ admin-{leader etcd nodename}-keya.pem

NOTE: Replace {leader etcd nodename} appropriately.

Check the status of the snapshot file /etcd_backup/etcd_backup.db that was created:
```
ETCD_API=3 sudo etcdctl snapshot --write-out=table status ~/etcd_backup/etcd_backup.db
```
Sample output:

HASH REVISION TOTAL KEYS TOTAL SIZE

107a4572 31002 1952 12 MB
Move the contents of the backup directory ~/etcd_backup to a safe location so you can restore the etcd database later.

NOTE: For a one node setup, execute the above commands on the single node.

Restoring Kubernetes etcd

Create the backup directory on all the three cluster nodes and copy the backed up files to that directory.
```
mkdir ~/etcd_backup/
sudo chown odimra:odimra ~/etcd_backup/
sudo chmod 755 ~/etcd_backup/
```
Copy all the files that were backed up and moved to a safe location to the directory ~/etcd_backup.

Generate the restore files for all nodes. Run the following command on all three nodes after replacing the hostnames and ip addresses appropriately.

On etcd node 1:

ETCDCTL_API=3 sudo etcdctl snapshot restore ~/etcd_backup/etcd_backup.db --name etcd1 --initial-cluster  etcd1=https://{IP address of first node}:2380,etcd2=https://{IP address of second node},etcd3=https://{IP address of third node}:2380 --initial-cluster-token k8s_etcd  --initial-advertise-peer-urls https://{IP address of first node}:2380

On etcd node 2:

ETCDCTL_API=3 sudo etcdctl snapshot restore ~/etcd_backup/etcd_backup.db --name etcd2 --initial-cluster  etcd1=https://{IP address of first node}:2380,etcd2=https://{IP address of second node},etcd3=https://{IP address of third node}:2380 --initial-cluster-token k8s_etcd  --initial-advertise-peer-urls https://{IP address of second node}:2380

On etcd node 3:

ETCDCTL_API=3 sudo etcdctl snapshot restore ~/etcd_backup/etcd_backup.db --name etcd3 --initial-cluster  etcd1=https://{IP address of first node}:2380,etcd2=https://{IP address of second node},etcd3=https://{IP address of third node}:2380 --initial-cluster-token k8s_etcd  --initial-advertise-peer-urls https://{IP address of third node}:2380

After the successful restore, directories ~/etcd1.etcd, ~/etcd2.etcd, and ~/etcd3.etcd are created on the three nodes respectively.

Stop all the Kube services (kube-apiserver, kube-controller, kube-schedule) on all the cluster nodes by running the following command:
```
sudo mv /etc/kubernetes/manifests/*.yaml ~/etcd_backup/
```
Stop the etcd service on all the cluster nodes:
```
sudo systemctl stop etcd
```
Move the current member directory to a backup member directory on all the three cluster nodes:
```
sudo mv /var/lib/etcd/member /var/lib/etcd/member.bkp
```
Restore the snapshot etcd db files to directory /var/lib/etcd on all the three cluster nodes by running the following commands:

On node 1:
```
sudo mv ~/etcd1.etcd/member /var/lib/etcd/
```
On node 2:
```
sudo mv ~/etcd2.etcd/member /var/lib/etcd/
```
On node 3:
```
sudo mv ~/etcd3.etcd/member /var/lib/etcd/
```
For one-node cluster deployment, run the following command:
```
sudo mv ~/default.etcd/member /var/lib/etcd
```
Start the etcd service on cluster nodes:
```
sudo systemctl start etcd
```
Restart all the kube services on all the three cluster nodes:
```
sudo mv ~/etcd_backup/*.yaml /etc/kubernetes/manifests/
```

NOTE: For a one-node setup, execute the above commands on the single node.

Backup and restore of ODIM etcd database

Taking a backup of ODIM etcd

Identify the leader etcd pod by running the following command inside all the three etcd pods:

kubectl exec -it {etcd pod name} bash -nodim

NOTE: Replace {etcd pod name} appropriately.

/opt/etcd/bin/etcdctl endpoint status --write-out=table --endpoints=https://etcd1:2379 --cacert=/opt/etcd/conf/rootCA.crt --cert=/opt/etcd/conf/odimra_etcd_server.crt --key=/opt/etcd/conf/odimra_etcd_server.key

NOTE: Replace etcd1 with etcd2 and etcd3 on second and third cluster nodes respectively.

Verify the output on each node. The node with IS LEADER value as true is the leader node.
Create a backup directory on the leader node and change the ownership and permission of the directory to odimra:
```
mkdir ~/etcd_odim_backup/
sudo chown odimra:odimra ~/etcd_odim_backup/
sudo chmod 755 ~/etcd_odim_backup/
```

Navigate to the /home/odimra directory and take the backup by running the following command inside etcd leader pod:

cd /home/odimra
/opt/etcd/bin/etcdctl snapshot save /home/odimra/etcd_backup.db \
 --endpoints=https://etcd:2379 \
 --cacert=/opt/etcd/conf/rootCA.crt\
 --cert=/opt/etcd/conf/odimra_etcd_server.crt  \
 --key=/opt/etcd/conf/odimra_etcd_server.key

Verify the backup file etcd_backup.db is available in /home/odimra directory.

Check the status of the snapshot file ~/etcd_backup.db that was created:
```
/opt/etcd/bin/etcdctl  snapshot status --write-out=table ~/etcd_backup.db
```
Sample output:

HASH REVISION TOTAL KEYS TOTAL SIZE

b31cc840 13 19 25KB
Take the file ~/etcd_backup.db out of the etcd leader pod to safe location which can be used to restore the etcd database later. Run the following command from one of the cluster node:
```
sudo kubectl cp odim/{leader etcd pod name}:/home/odimra/etcd_backup.db ~/etcd_odim_backup/etcd_backup.db
```
NOTE: Replace {leader etcd pod name} appropriately.

NOTE: For a one node setup, execute the above commands on the single node.

Restoring ODIM etcd

Create the backup directory if the directory is not present on one of the cluster nodes and copy the backed up file to that directory.
```
mkdir ~/etcd_odim_backup/
sudo chown odimra:odimra ~/etcd_odim_backup/
sudo chmod 755 ~/etcd_odim_backup/
```
Copy the file that was backed up and moved to safe location to the directory ~/etcd_odim_backup on one of the cluster nodes.
Copy the backup file inside the etcd container from the cluster node:
```
kubectl cp ~/etcd_odim_backup/etcd_backup.db odim/{leader etcd container name}:/home/odimra/etcd_backup.db
```
NOTE: Replace {leader etcd container name} appropriately in all commands.

Login to the leader etcd container and restore the backed up etcd configuration:

kubectl exec -it {leader etcd container name}  bash -nodim

cd /home/odimra

/opt/etcd/bin/etcdctl snapshot restore /home/odimra/etcd_backup.db --endpoints=https://etcd:2379  --cacert=/opt/etcd/conf/rootCA.crt  --cert=/opt/etcd/conf/odimra_etcd_server.crt  --key=/opt/etcd/conf/odimra_etcd_server.key

Verify that a directory by name default.etcd is created under /home/odimra in the leader etcd container.
Copy the restored directory /home/odimra/default.etcd from the leader etcd container to the Kubernetes cluster node.
```
kubectl cp odim/{leader etcd container name}:/home/odimra/default.etcd/member" ~/etcd_odim_backup/member
```
Copy the restored directory ~/etcd_odim_backup/member from Kubernetes cluster node to the remaining two etcd nodes.
```
kubectl cp ~/etcd_odim_backup/member odim/{etcd container name}:/home/odimra/member
```
Replace {etcd container name} appropriately.

Login to leader etcd container first and move the restored directory member to /opt/etcd/data.

kubectl exec -it {leader etcd container name}  bash -nodim
cd /opt/etcd/data
mv member member.bkp
cp -r /home/odimra/member /opt/etcd/data/member

Repeat step 8 on other two etcd containers.

NOTE: For a one node setup, execute the above commands on the single node.

Backup and restore of Redis

Create a directory to store the backup rdb files and append-only files.
```
mkdir <backup directory>/backup
```
For three-node deployment, get the name of the primary pod to collect the backup snapshot file and append-only directory to restore them later (either ondisk or inmemory database).
```
kubectl get pods -nodim | grep redis | grep primary
```
Output:
```
redis-ha-inmemory-primary-0
```
```
redis-ha-ondisk-primary-0
```
NOTE: For one-node deployment, enter kubectl get pods -nodim | grep redis to get the name of the pod to collect the backup snapshot file and append-only directory to restore them later (either ondisk or inmemory database).

Copy the rdb file and aof directory from the primary pod.

kubectl cp odim/<pod-name>:/redis-data/dump.rdb <backup directory>/backup/dump.rdb

kubectl cp odim/<pod-name>:/redis-data/appendonlydir <backup directory>/backup/appendonlydir

For example (on-disk):

kubectl cp odim/redis-ha-ondisk-primary-0:/redis-data/dump.rdb <backup directory>/backup/dump.rdb

kubectl cp odim/redis-ha-ondisk-primary-0:/redis-data/appendonlydir <backup directory>/backup/appendonlydir

For example(in-memory):

kubectl cp odim/redis-ha-inmemory-primary-0:/redis-data/dump.rdb <backup directory>/backup/dump.rdb

kubectl cp odim/redis-ha-inmemory-primary-0:/redis-data/appendonlydir <backup directory>/backup/appendonlydir

These are the backup files to be restored.

Copy the above backup files to the pod to restore them.

kubectl cp <Copied directory>/backup/dump.rdb odim/<pod-name>:/redis-data/dump.rdb-1

kubectl cp <Copied directory>/backup/appendonlydir  odim/<pod-name>:/redis-data/appendonlydir.old

For example:

kubectl cp <Copied directory>/backup/dump.rdb odim/redis-ha-ondisk-primary-0:/redis-data/dump.rdb-1

kubectl cp <Copied directory>/backup/appendonlydir odim/redis-ha-ondisk-primary-0/redis-data/appendonlydir.old

kubectl cp <Copied directory>/backup/dump.rdb odim/redis-ha-inmemory-primary-0:/redis-data/dump.rdb-1

kubectl cp <Copied directory>/backup/appendonlydir  odim/redis-ha-inmemory-primary-0/redis-data/appendonlydir.old

Log in to the pod.

kubectl exec -it <podname> -nodim bash

For example:

kubectl exec -it redis-ha-ondisk-primary-0 -nodim bash

kubectl exec -it redis-ha-inmemory-primary-0 -nodim bash

Log in to Redis CLI and disable append-only configuration to restore the data back.

redis-cli --tls --cert /etc/odimra_certs/odimra_server.crt --key /etc/odimra_certs/odimra_server.key --cacert /etc/odimra_certs/rootCA.crt -a <password>

CONFIG SET "appendonly" no

Delete the data available to verify later, if the restore option works (optional).
```
keys *
```
```
FLUSHALL
```
Exit from the Redis CLI and move to the redis-data directory.

Remove the existing rdb file and aof directory and replace the backed up ones with the name.

cd /redis-data

rm -rf dump.rdb appendonlydir

mv dump.rdb-1 dumb.rdb

mv appendonlydir.old appendonlydir

Get the pods of the Redis (either in-memory or on-disk) and restart them.

kubectl get pods -nodim | grep redis | grep inmemory

kubectl get pods -nodim | grep redis | grep ondisk

kubectl delete pods <pod1> <pod2>..<pod3> -nodim

For example:

kubectl delete pods redis-ha-inmemory-primary-0 redis-ha-inmemory-secondary-0 redis-ha-inmemory-secondary-1 -nodim

Once all the pods have started and are in running state, log in to the pod.

kubectl exec -it <podname> -nodim bash

For example:

kubectl exec -it redis-ha-ondisk-primary-0 -nodim bash

kubectl exec -it redis-ha-inmemory-primary-0 -nodim bash

Log in to Redis CLI and check for the old data.

redis-cli --tls --cert /etc/odimra_certs/odimra_server.crt --key /etc/odimra_certs/odimra_server.key --cacert /etc/odimra_certs/rootCA.crt -a <password>

Backup and restore of Resource Aggregator for ODIM and plugin configurations

You can take a backup of all Resource Aggregator for ODIM and plugin configurations in a single file or in different files. The following procedure has instructions to take a backup of Resource Aggregator for ODIM and plugin configurations in a single file.

List down all the configmaps present in the odim namespace:

kubectl get cm -n <odim_namespace>

For example:

kubectl get cm -nodim

The following sample output appears:

NAME                    DATA   AGE
configure-hosts         1      10d
iloplugin-config        1      3d23h
kube-root-ca.crt        1      11d
odimra-config           1      10d
odimra-platformconfig   1      10da

Copy all config maps to a file:

kubectl get cm -nodim -o yaml > odim_configs.yaml

Remove the fields such as resourceVersion, uid, and creationtimestamp from the yaml file. The backup file of all configurations is ready.
To restore the configurations, apply the configuration backup using the kubectl apply command:
```
kubectl apply -f <file-name>
```
For example:
```
kubectl apply -f odim_configs.yaml
```
The following sample output appears:
```
configmap/configure-hosts configured
configmap/iloplugin-config configured
configmap/kube-root-ca.crt configured
configmap/odimra-config configured
configmap/odimra-platformconfig configured
```
Testing the backup and restore operation
1. After taking a backup of the configuration files, re-install Resource Aggregator for ODIM with different configurations.
2. Restore the old backup configurations and verify that the parameters would be updated as present in the backup file.

Use cases for Resource Aggregator for ODIM

Adding a server into the resource inventory

To add a server, perform HTTP POST on the following URI with the request payload having the following details:

The BMC address (IP address or hostname)
The username and password of the BMC user account
A link to the connection method having the details of the plugin of your choice

URI: /redfish/v1/AggregationService/Actions/AggregationSources

Before adding a server, generate a certificate for it using the root CA certificate of Resource Aggregator for ODIM. To use your own root CA certificate to generate a certificate, you must first append it to the existing root CA certificate.

NOTE: To add a server using FQDN, add the server IP address and FQDN under the etcHostsEntries parameter in the kube_deploy_nodes.yaml file on the deployment node and run the following command:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml \
--upgrade configure-hosts

This action discovers information about a server and performs a detailed inventory of it. After successful completion, you will receive an aggregation source Id of the added BMC. Save it as it is required to identify it in the resource inventory later.

After the server is successfully added as an aggregation source, it will also be available as a computer system resource at /redfish/v1/Systems/ and a manager resource at /redfish/v1/Managers/.

For more information such as curl command, sample request, and sample response, see Adding a server as an aggregation source section in Resource Aggregator for Open Distributed Infrastructure Management™ API Reference and User Guide.

Contributing to the open-source community

Welcome to the GitHub open-source community for Resource Aggregator for ODIM!

If you want to contribute to the project to make it better, your help is welcome and highly appreciated. Contribution is a great way of extending the understanding and value of open-source software and development models, towards a common goal. Apart from learning more about social coding on GitHub, new technologies and their ecosystems, you can keep the discussion forums active by sharing knowledge, asking right questions, finding information through effective collaborations as well as make constructive, helpful bug reports, feature requests, and the noblest of all contributions—a good, clean pull request (PR). All bugs or feature requests must be submitted through a PR to the development branch and are expected to have unit tests and/or integration tests with the PR.

Creating a PR

Prerequisite: Follow the project's contribution instructions, if any.

Create a personal fork of the project on GitHub.
Clone the fork on your local machine. Your remote repo on GitHub is called origin.
Add the original repository as a remote called upstream.
If you created your fork a while ago, be sure to pull upstream changes into your local repository.
Create a new branch to work on. Branch from development (if it exists), else from the main branch.
Implement/fix your feature, comment your code.
Follow the code style of the project, including indentation.
If the project has tests, run them!
Write or adapt tests as needed.
Add or change the documentation as needed.
Squash your commits into a single commit with git's interactive rebase. Create a new branch, if necessary.
Push your branch to your fork on GitHub, the remote origin.
From your fork, open a PR in the correct branch. Target the project's development branch if there is one, else go for main.
Once the pull request is approved and merged, pull the changes from upstream to your local repository and delete your extra branch(es).

Last, but not the least, always write your commit messages in the present tense. Your commit message should describe what the commit is, when is it applied, and what it does to the code – not what you did to the code.

Setting proxy configuration

Open the /etc/environment file to edit.
```
sudo vi /etc/environment
```

Add the following lines and save:

export http_proxy=<your_HTTP_proxy_address>
export https_proxy=<your_HTTP_proxy_address>
no_proxy="127.0.0.1,localhost,localhost.localdomain,xxx.xxx.xxx.9/12,<Deployment_Node_IP_address>,\
<Comma-separated-list-of-Ip-addresses-of-all-cluster-nodes>"

NOTE: When you add a node to the cluster, ensure to update no_proxy with the IP address of the new node.

Example:

export http_proxy=<your_HTTP_proxy_address>
export https_proxy=<your_HTTP_proxy_address>
no_proxy="127.0.0.1,localhost,localhost.localdomain,xxx.xxx.xxx.10/12,   <Deployment_Node_IP_address>,<Cluster_Node1_IP>,\
<Cluster_Node1_IP>,<Cluster_Node2_IP>,<Cluster_Node3_IP>"

Run the following command:
```
source /etc/environment
```

Setting up time sync across nodes

This procedure shows how to set up time synchronization across all the nodes (deployment node and cluster nodes) of a Kubernetes cluster using Network Transfer Protocol (NTP).

Type the following command:
```
sudo apt install chrony
```
Type the following command:
```
sudo vi /etc/chrony/chrony.conf
```

Add the following lines and save:

# Welcome to the chrony configuration file. See chrony.conf(5) for more
# information about usuable directives.
# This will use (up to):
# - 4 sources from ntp.ubuntu.com which some are ipv6 enabled
# - 2 sources from 2.ubuntu.pool.ntp.org which is ipv6 enabled as well
# - 1 source from [01].ubuntu.pool.ntp.org each (ipv4 only atm)
# This means by default, up to 6 dual-stack and up to 2 additional IPv4-only
# sources will be used.
# At the same time it retains some protection against one of the entries being
# down (compare to just using one of the lines). See (LP: #1754358) for the
# discussion.
#
# About using servers from the NTP Pool Project in general see (LP: #104525).
# Approved by Ubuntu Technical Board on 2011-02-08.
# See http://www.pool.ntp.org/join.html for more information.
# pool ntp.ubuntu.com iburst maxsources 4
# pool 0.ubuntu.pool.ntp.org iburst maxsources 1
# pool 1.ubuntu.pool.ntp.org iburst maxsources 1
# pool 2.ubuntu.pool.ntp.org iburst maxsources 2
server <NTP_server_IP_address> prefer iburst
# This directive specify the location of the file containing ID/key pairs for
# NTP authentication.
keyfile /etc/chrony/chrony.keys
# This directive specify the file into which chronyd will store the rate
# information.
driftfile /var/lib/chrony/chrony.drift
# Uncomment the following line to turn logging on.
#log tracking measurements statistics
# Log files location.
logdir /var/log/chrony
# Stop bad estimates upsetting machine clock.
maxupdateskew 100.0
# This directive enables kernel synchronisation (every 11 minutes) of the
# real-time clock. Note that it can’t be used along with the 'rtcfile' directive.
rtcsync
# Step the system clock instead of slewing it if the adjustment is larger than
# one second, but only in the first three clock updates.
makestep 1 3

Type the following commands:

sudo systemctl restart chrony

sudo systemctl enable chrony

Configuring proxy for Docker

NOTE: Before performing the following steps, ensure the http_proxy, https_proxy, and no_proxy environment variables are set.

[Optional] If the following content is not present in the /etc/environment file, add it:

cat << EOF | sudo tee -a /etc/environment
http_proxy=${http_proxy}
https_proxy=${https_proxy}
no_proxy=${no_proxy}
EOF

Update proxy information in the Docker service file:

sudo mkdir -p /etc/systemd/system/docker.service.d

cat << EOF | sudo tee /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=${http_proxy}"
Environment="HTTPS_PROXY=${https_proxy}"
Environment="NO_PROXY=${no_proxy}"
EOF

Run the following commands to update proxy information in the user Docker config file:

mkdir ~/.docker

sudo chown ${USER}:${USER} ~/.docker -R

sudo chmod 0700 ~/.docker

cat > ~/.docker/config.json <<EOF
 {
  "proxies":
  {
   "default":
   {
   "httpProxy": "${http_proxy}",
   "httpsProxy": "${https_proxy}",
   "noProxy": "${no_proxy}"
   }
 }
}
EOF

Installing Docker

Run the following commands:

sudo apt-get install -y apt-transport-https=2.4.10 ca-certificates=20230311ubuntu0.22.04.1 curl=7.81.0-1ubuntu1.13

sudo apt-get install -y gnupg-agent=2.2.27-3ubuntu2.1 software-properties-common=0.99.22.7

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt-get install -y docker-ce=5:24.0.5-1~ubuntu.22.04~jammy docker-ce-cli=5:24.0.5-1~ubuntu.22.04~jammy  containerd.io --allow-downgrades

NOTE: If the current version of a package is not found, please run the following command to check for the latest available version of that package and install the first version listed in the output.

sudo apt-cache madison <package name>

Configure overlay storage for Docker:

cat << EOF | sudo tee /etc/docker/daemon.json
{
    "exec-opts": ["native.cgroupdriver=systemd"],
    "log-driver": "json-file",
    "storage-driver": "overlay2"
}
EOF

Perform the following steps to check and create Docker group if doesn't exist:
1. Check if the Docker group exists:
```
getent group docker
```
  Example output: docker:x:998:
2. Create the Docker group:
```
sudo groupadd docker
```
Configure to use Docker CLI without sudo access:
```
sudo usermod -aG docker $USER
```
Activate the user added to the Docker group:
```
newgrp docker
```
NOTE: If you are unable to access Docker CLI without sudo even after performing this step, log out and log back in so that Docker group membership is re-evaluated.

Restart Docker service:

sudo systemctl enable docker

sudo systemctl restart docker

Verify that Docker is successfully installed:
```
docker run hello-world
```

Running curl commands on a different server

To run curl commands on a different server, perform the following steps to provide the rootCA.crt file.

Navigate to the path specified for the odimCertsPath parameter in the kube_deploy_nodes.yaml file on the deployment node.
Copy the rootCA.crt file.
Log in to your server and paste the rootCA.crt file in a folder.
Open the /etc/hosts file to edit.
Scroll to the end of the file, add the following line, and then save:
```
<hostvm_ipv4_address> <FQDN>
```

Check if curl is working:

curl --cacert rootCA.crt 'https://{odim_host}:{port}/redfish/v1'

NOTE: To avoid using the --cacert flag in every curl command, add rootCA.crt in the ca-certificates.crt file available in this path: /etc/ssl/certs/ca-certificates.crt. You can access the base URL using a REST client. To access it using a REST client, add the rootCA.crt file of Resource Aggregator for ODIM to the browser where the REST client is launched.

Using protoc compiler

The protoc compiler provides a language-neutral, platform-neutral, extensible mechanism for defining communications protocols together with gRPC framework for communicating with Resource Aggregator for ODIM services. You can install the compiler, and create and compile your own protocols to the existing code.

Install the protoc compiler by performing the following tasks:
1. Download the protoc compiler package:
```
wget https://github.com/protocolbuffers/protobuf/releases/download/v3.19.1/protoc-3.19.1-linux-x86_64.zip -P /tmp/'
```
2. Install unzip (if not already installed):
```
sudo apt install unzip
```
3. Unzip the the protoc compiler package to the proto_files directory:
```
unzip /tmp/protoc-3.19.1-linux-x86_64.zip -d proto_files
```
4. Navigate to the bin directory in the proto_files directory:
```
cd proto_files/bin
```
5. Copy protoc from this bin directory to /usr/bin:
```
sudo cp protoc /usr/bin
```
6. Navigate to the include directory in the proto_files directory:
```
cd ../include
```
7. Run the following command:
```
sudo cp -r google /usr/local/include/
```

Install protoc-gen-go and protoc-gen-go-grpc plugins:

go install google.golang.org/grpc/cmd/protoc-gen-go-grpc

go get -u github.com/golang/protobuf/protoc-gen-go@v1.3.2

Create proto go stub files by performing the following tasks:

Navigate to the ODIM source path and create script file as generate_proto.sh.

Add the following content to it:

#!/bin/bash -x
## Generting protoc

protos=("account" "aggregator" "auth" "chassis" "events" "fabrics" "managers" "role" "session" "systems" "task" "telemetry" "update" "licenses")

for str in ${protos[@]}; do
proto_path="$<your_odim_directory>/lib-utilities/proto/$str"
proto_file_name="$str.proto"
if [ $str == 'auth' ]
then
proto_file_name="odim_auth.proto"
fi
protoc --go_opt=M$proto_file_name=./ --go_out=plugins=grpc:$proto_path --proto_path=$proto_path $proto_file_name
done

Run the script file:
```
bash ./generate_proto.sh
```

Using your own CA certificates and keys

Generate the following certificates and store them in a folder on the deployment node:
- odimra_rsa.private—It must be generated only once before deploying the Resource Aggregator and plugin services.
- odimra_rsa.public—It must be generated only once before deploying the Resource Aggregator and plugin services.
  
  NOTE: Ensure not to replace the RSA public and private keys. Replacing them results in loss of data and requires reinstallation. If you are generating your own CA certificates to replace the existing CA certificates, move the existing odimra_rsa.public and odimra_rsa.private files to the folder where you are generating all the other certificates.
- rootCA.crt—Root CA certificate.
- odimra_server.crt—Certificate to be used by the API gateway and the Resource Aggregator and plugin components.
- odimra_server.key—Private key to be used by the API gateway and the Resource Aggregator and plugin components.
- odimra_kafka_client.crt—Kafka certificate.
- odimra_kafka_client.key—Kafka key.
- kafka.keystore.jks—Keystore of type jks used by Kafka servers for TLS-based communication.
- kafka.truststore.jks—Truststore of type jks. It contains CA certificates, used by Kafka server to validate certificates of the client that is contacting the Kafka server.
- zookeeper.keystore.jks—Keystore of type jks used by Zookeeper for TLS-based communication.
- zookeeper.truststore.jks—Truststore of type jks. It contains CA certificates, used by Zookeeper to validate certificates of the client that is contacting it.
While generating these certificates:
- Ensure that odimra_server.crt has the SAN entry of FQDN specified in the kube_deploy_nodes.yaml file.
- Ensure that odim_server.crt and odim_kafka_client.crt have the following SAN entries for all the plugins you want to deploy.
  
  Examples: grfplugin: grfplugin,grfplugin-events.
- Ensure that kafka.truststore.jks and kafka.truststore.jks have the following SAN entries:
```
DNS.1 = kafka
DNS.2 = kafka1.kafka.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.3 = kafka2.kafka.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.4 = kafka3.kafka.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.5 = kafka-ext
DNS.6 = kafka1-ext
DNS.7 = kafka2-ext
DNS.8 = kafka3-ext
```
- Ensure that zookeeper.truststore.jks and zookeeper.truststore.jks have the following SAN entries:
```
DNS.1 = zookeeper
DNS.2 = zookeeper1.zookeeper.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.3 = zookeeper2.zookeeper.${ODIMRA_NAMESPACE}.svc.cluster.local
DNS.4 = zookeeper3.zookeeper.${ODIMRA_NAMESPACE}.svc.cluster.local
```
Replace {ODIMRA_NAMESPACE} with the value specified for namespace in the kube_deploy_nodes.yaml file.
Update odimCertsPath with the path of the folder where you have stored the certificates in the kube_deploy_nodes.yaml file.
[Optional] Perform this step only after you have successfully deployed the Resource Aggregator and plugin services.

If you want to replace the existing CA certificates, run the following command:
```
python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --upgrade odimra-secret
```

Result: The existing certificates are replaced with the new certificates and the Resource Aggregator pods are restarted.

Default ports used by the Resource Aggregator, plugins, and third-party services can be found in the table in the Adding a plugin into the Resource Aggregator for ODIM framework section.

Deploying the GRF plugin

Prerequisites

Kubernetes cluster is set up and the Resource Aggregator is successfully deployed.

Create a directory called plugins on the deployment node.
```
mkdir -p ~/plugins
```
In the plugins directory, create a directory called grfplugin.
```
mkdir ~/plugins/grfplugin
```

On the deployment node, copy the GRF configuration file and the hook script to ~/plugins/grfplugin.

cp ~/ODIM/odim-controller/helmcharts/grfplugin/grfplugin-config.yaml ~/plugins/grfplugin

cp ~/ODIM/odim-controller/helmcharts/grfplugin/grfplugin.sh ~/plugins/grfplugin

Open the GRF plugin configuration YAML file.

vi ~/plugins/grfplugin/grfplugin-config.yaml

Sample grfplugin-config.yaml file:

grfplugin:
  eventListenerNodePort: 30081
  rootServiceUUID: 65963042-6b99-4206-8532-dcd085a835b1
  username: admin
  password: "AQ6h8PB8OVW7rBXHbDg75ic4ZP7cKIWgNHZZ41Qb4DwvZQ8Q-KEl0Fe26ddo_DLrs7MkLcNDplREwxlLOPvgFg=="
  lbHost: <Ngnix_virtual_IP_address>
  lbPort: <Ngnix_plugin_port>
  logPath: /var/log/grfplugin_logs
  logsOnConsole: false
  messageBusType: Kafka
  messageBusQueue: REDFISH-EVENTS-TOPIC

Other parameters have default values. Optionally, you can modify them according to your requirements. To know more about each parameter, see Plugin configuration parameters.

Update the following parameters in the plugin configuration file:
- lbHost: IP address of the cluster node where the GRF plugin will be installed for one node cluster configuration. For three node cluster configuration, (haDeploymentEnabled is true), lbHost is the virtual IP address configured in Nginx and Keepalived.
- lbPort: Default port is 30081 for one node cluster configuration. For three node cluster configuration, (haDeploymentEnabled is true), lbport must be assigned with a free port (preferably above 45000) available on all cluster nodes. This port is used as nginx proxy port for the plugin.
  
  NOTE: The lbport is used as proxy port for eventlistenernodeport, which is used for subscribing to events.
- grfPluginrootServiceUUID: RootServiceUUID to be used by the GRF plugin service. Generate a new UUID by executing the command uuidgen.
- MessageBusType: Event message bus type. The supported value is Kafka. RedisStreams is not supported as the event message bus type for GRF plugin.
Other parameters can have default values. Optionally, you can update them with values based on your requirements. For more information on each parameter, see Plugin configuration parameters.
Generate the Helm package for the GRF plugin on the deployment node.
1. Navigate to odim-controller/helmcharts/grfplugin.
```
cd ~/ODIM/odim-controller/helmcharts/grfplugin
```
2. Create grfplugin Helm package at ~/plugins/grfplugin:
```
helm package grfplugin -d ~/plugins/grfplugin
```
  The Helm package for the GRF plugin is created in the tgz format.
Save the GRF plugin Docker image on the deployment node at ~/plugins/grfplugin.
```
docker save grfplugin:4.1 -o ~/plugins/grfplugin/grfplugin.tar
```
Navigate to the ODIM directory.
```
cd ODIM
```
Copy the proxy configuration file install/templates/grfplugin_proxy_server.conf.j2 to ~/plugins/grfplugin.
```
cp install/templates/grfplugin_proxy_server.conf.j2 ~/plugins/grfplugin
```
Important: Do NOT change the value of any parameter in this file.
Navigate to the /ODIM/odim-controller/scripts directory on the deployment node.
```
cd ~/ODIM/odim-controller/scripts
```
Open the kube_deploy_nodes.yaml file to edit.
```
 vi kube_deploy_nodes.yaml
```

Specify values for the following parameters in the kube_deploy_nodes.yaml file:

Parameter	Value
connectionMethodConf	The connection method associated with the GRF plugin: ConnectionMethodVariant: `Compute:BasicAuth:GRF_v2.0.0` Check if it is there already before updating. If yes, do not add it again.
odimraKafkaClientCertFQDNSan	The FQDN to be included in the Kafka client certificate of Resource Aggregator for ODIM for deploying the GRF plugin:grfplugin, grfplugin-events Add these values to the existing comma-separated list.
odimraServerCertFQDNSan	The FQDN to be included in the server certificate of Resource Aggregator for ODIM for deploying the GRF plugin: grfplugin, grfplugin-events. Add these values to the existing comma-separated list.
odimPluginPath	The path of the directory where the GRF Helm package, the `grfplugin` image, and the modified `grfplugin-config.yaml` are copied.

Example:

odimPluginPath: /home/user/plugins
    odimra:
      groupID: 2021
      userID: 2021
      namespace: odim
      fqdn:
      rootServiceUUID:
      haDeploymentEnabled: True
      connectionMethodConf:
      - ConnectionMethodType: Redfish
        ConnectionMethodVariant: Compute:BasicAuth:GRF_v2.0.0
      odimraKafkaClientCertFQDNSan: grfplugin,grfplugin-events
      odimraServerCertFQDNSan: grfplugin,grfplugin-events

Move odimra_kafka_client.key, odimra_kafka_client.crt, odimra_server.key, and odimra_server.crt stored in odimCertsPath to a different folder.

NOTE: odimCertsPath is the absolute path of the directory where the certificates required by the services of Resource Aggregator for ODIM are present. See the Odim-controller configuration parameters section in this document for more information.

Update odimra-secrets:

 python3 odim-controller.py --config /home/${USER}/ODIM/odim-controller/scripts/kube_deploy_nodes.yaml --upgrade odimra-secret

Run the following command:

  python3 odim-controller.py --config \ 
  /home/${USER}/ODIM/odim-controller/scripts\
  /kube_deploy_nodes.yaml --upgrade odimra-config

Install the GRF plugin:

python3 odim-controller.py --config \
/home/${USER}/ODIM/odim-controller/scripts\
/kube_deploy_nodes.yaml --add plugin --plugin grfplugin

Run the following command on the cluster nodes to verify the GRF plugin pod is up and running:
```
 kubectl get pods -n odim
 Example output showing the GRF plugin pod details:
```
NAME READY STATUS RESTARTS AGE grfplugin-5fc4b6788-2xx97 1/1 Running 0 4d22h
Navigate to ~/ODIM/odim-controller/scripts.
```
  cd ~/ODIM/odim-controller/scripts
```
Add the GRF plugin into the Resource Aggregator for ODIM framework.

Replacing an unreachable controller node with a new one

Set the following environment variables on the deployment node:

export NEW_CONTROLLER_NODE_IP=<IP_address_of_new_controller_node>

export NEW_CONTROLLER_NODE_HOSTNAME=<Hostname_of_new_controller_node>

export DEPLOYMENT_ID=<Deployment_ID_of_the_cluster_being_updated>

export ODIM_CONTROLLER_SRC_PATH=/home/${USER}/ODIM/odim-controller

export ODIM_CONTROLLER_CONFIG_FILE=/home/${USER}/ODIM/\
odim-controller/scripts/kube_deploy_nodes.yaml

export K8S_INVENTORY_FILE=${ODIM_CONTROLLER_SRC_PATH}/kubespray/inventory/k8s-cluster-${DEPLOYMENT_ID}/hosts.yaml

Replace {ODIM_CONTROLLER_SRC_PATH} with:

/home/$\{USER\}/ODIM/odim-controller.

Replace {DEPLOYMENT_ID} with the deployment Id of the cluster being updated.

Perform the following steps on one of the controller nodes:
1. Mark the failed controller node as unschedulable:
```
kubectl cordon <Failed_Controller_HostName>
```
2. Delete the failed controller node from the cluster:
```
kubectl delete node <Failed_Controller_HostName>
```
3. Get the container name of etcd:
```
sudo docker ps | grep etcd | awk '{print $10}'
```
4. List the etcd members to obtain the member Id of the failed controller node.
```
sudo docker exec -it <etcd_container_name> etcdctl member list
```
5. Remove the failed controller node from the etcd cluster:
```
sudo docker exec -it <etcd_container_name> etcdctl member remove <failed_node_etcd_member_id>
```

Perform the following steps on the deployment node:

Enable login without a password for the new controller node.

/usr/bin/ssh-copy-id -o StrictHostKeyChecking=no -i ~/.ssh/id_rsa.pub ${USER}@${New_Controller_Node_IP}

Verify that time on the new controller node is in sync with the deployment node and other cluster nodes.
Edit ${K8S_INVENTORY_FILE} to:
- Remove the failed controller node details.
- Add the new controller node details under the following sections:
  - etcd
  - kube_control_plane
  - kube_node
  - hosts
```
vi ${K8S_INVENTORY_FILE}
```
Edit {ODIM_CONTROLLER_SRC_PATH}/kubespray/inventory/k8s-cluster-${DEPLOYMENT_ID}/group_vars/all/all.yml to:
- Update the no_proxy parameter with the new controller node IP.
- Remove the failed controller node IP from the no_proxy list.

ansible-playbook -K -i ${K8S_INVENTORY_FILE} --become \
--become-user=root --extra-vars "host=${NEW_CONTROLLER_NODE_HOSTNAME}" \
k8_copy_image.yaml

When prompted for password, enter the sudo password of the node.

cd ${ODIM_CONTROLLER_SRC_PATH}/kubespray

ansible-playbook -K -i ${K8S_INVENTORY_FILE} \
--become --become-user=root --limit=etcd,kube_control_plane \
-e ignore_assert_errors=yes cluster.yml

Run the following command on any of the cluster nodes:

kubectl get nodes -o wide

If any of the nodes are listed as "Ready,Unschedulable", run the following commands on any of the existing controller nodes:

kubectl uncordon <unschedulable_controller_node_name>

cd ${ODIM_CONTROLLER_SRC_PATH}/odimra

cp ${ODIM_CONTROLLER_CONFIG_FILE} ${ODIM_CONTROLLER_SRC_PATH}\
/odimra/roles/pre-install/files/helmcharts/helm_config_values.yaml

cp ${ODIM_CONTROLLER_CONFIG_FILE} ${ODIM_CONTROLLER_SRC_PATH}\
/odimra/roles/odimra-copy-image/files/odimra_config_values.yaml

ansible-playbook -K -i ${K8S_INVENTORY_FILE} \
--become --become-user=root --extra-vars \

CI process

GitHub action workflows, also known as checks, are added to the ODIM repository. They are triggered whenever a Pull Request (PR) is raised against the development branch. The result from the workflow execution is then updated to the PR.

NOTE: You can review and merge PRs only if the checks are passed.

Following checks are added as part of the CI process:

Sl No.	Workflow Name	Description
1	`build_unittest.yml`	Builds and runs Unit Tests with code coverage enabled.
2	`build_deploy_test.yml`	Builds, deploys, runs sanity tests, and uploads build artifacts (like odimra logs).

These checks run in parallel and take a few minutes to complete.
