Deployment types

UPI

Azure

File osServicePrincipal.json in ~/.azure/ directory with proper credentials is required. The file looks like this:

{
  "subscriptionId": "...",
  "clientId": "...",
  "clientSecret": "...",
  "tenantId": "..."
}

To deploy ocs-ci cluster on Azure platform using one of OCS QE subscriptions, you need to specify one deployment config file from conf/deployment/azure/ directory (which one to use depends on the type of deployment one needs to use) and also one config file with azure base_domain value (either conf/ocsci/azure_qe_rh_ocs_com_domain.yaml or conf/ocsci/azure2_qe_rh_ocs_com_domain.yaml or similar newly created with proper base_domain configuration), because each azure subscription has it's own domain name.

IBM Cloud

This platform supports deployment of OCP cluster + OCS cluster on top of it. For IPI deployments, please see the IPI section below.

Requirements

  • Have locally installed ibmcloud CLI, follow official documentation.
  • Install required plugins for IBM Cloud CLI via command: ibmcloud plugin install PLUGIN_NAME -f -r 'IBM Cloud'
    • infrastructure-service
    • kubernetes-service
  • Provide credential config file + credential config file described bellow to run-ci command via --ocsci-conf parameters.

Supported providers

  • vpc-gen2 - This is first implemented supported provider for IBM cloud.
  • classic - Not supported yet.
  • satellite - Not supported yet.

Configuration files

  • conf/deployment/ibmcloud/ibm_cloud_vpc_cluster.yaml - this file can be used for deployment on IBM Cloud - this config is for VPC gen 2 provider.

  • conf/deployment/ibmcloud/ibm_cloud_vpc_cluster_without_cos.yaml - this file can be used for deployment on IBM Cloud - this config is for VPC gen 2 provider without COS secret created.

You will need to create also credential file with secret data which should never be shared publicly in this repository. All needed values are mentioned as placeholders and commented out in conf/deployment/ibmcloud/ibm_cloud_vpc_cluster.yaml

But an example is pasted also here:

# This is the basic config for IBM cloud usage
---
ENV_DATA:
  vpc_id: VPC ID PLACEHOLDER
  subnet_id: SUBNET ID PLACEHOLDER
  cos_instance: COS INSTANCE PLACEHOLDER
AUTH:
  ibmcloud:
    api_key: IBM CLOUD API KEY PLACEHOLDER
    account_id: ACCOUNT ID PLACEHOLDER
    ibm_cos_access_key_id: KEY PLACEHOLDER
    ibm_cos_secret_access_key: SECRET PLACEHOLDER
DEPLOYMENT:
  ocs_secret_dockerconfigjson: BASE64 OF QUAY SECRET PLACEHOLDER

How to get API key

API key creation is - one time action and is required for run deployment and other operation with ibmcloud CLI as we are using login with this API key.

Follow this documentation access API Key.

Command: ibmcloud login -u [email protected] -p PASSWORD_PLACEHOLDER -c ACCOUNT_ID_PLACEHOLDER -r us-east

You should get this info as output where you can get the key:

Please preserve the API key! It cannot be retrieved after it's created.

ID            ApiKey-ID
Name          my-api-key
Description
Created At    2020-10-19T15:05+0000
API Key       OUR_KEY
Locked        false

How to get COS keys

Please follow official documentation.

Deployment types

IPI

IPI deployments to IBM Cloud are supported for ODF versions >= 4.10.

Requirements
  1. OCP installer version >= 4.10
  2. ibmcloud ipi config file (e.g. conf/deployment/ibmcloud/ipi_3az_rhcos_3m_3w.yaml)
  3. ibmcloud account data. This data should appear as follows in the ocsci config:
#AUTH:
#  ibmcloud:
#    account_id: ACCOUNT ID PLACEHOLDER
#    api_key: IBM CLOUD API KEY PLACEHOLDER

Managed

This deployment type is managed - there is no openshift-installer used for installing the cluster, but we are using ibmcloud CLI to create the cluster.

As we rely on matadata.json file to store cluster name and few other details like ID we are creating this json file from data which we get from command: ibmcloud ks cluster get --cluster CLUSTER_NAME -json and updating with values we usually read from this file like clusterName and clusterID.

The kubeconfig is generated by command: ibmcloud ks cluster config --cluster cluster-name --admin --output yaml

And stored in the same structure like openshift-installer does in cluster dir.

There are added just worker nodes as par to the deployment as master nodes are not directly accessible in this kind of deployment.

Known issues

Global pull secret

There is no way how to update global pull secret cause of missing machineConfig. So as workaround to be able install internal build from private quay repository we need to create secret and add it to two namespaces:

  • openshift-marketplace - in order to be able to create catalogSource
  • openshift-storage - in order to be able install OCS operator

We need to then assign this secret to all service accounts in mentioned namespaces.

Note: In openshift-storage namespace there are not all service accounts created before deployment. As workaround we need to run deployment - then we see that pods will not start cause of image pull error, but service account will be created. Then we need to again assign secret to all service accounts and remove all pods in the openshift-storage namespace. Then pods will be created again and successfully pull the images.

Must-gather

There is also problem with secret in must-gather. As must gather is always created in temporary created namespace with random name we cannot use the same mechanism mentioned above. As a workaround we are able to use live must-gather after the GA of specific version. Or we have to use upstream image. By default we are using upstream image for IBM Cloud.

Config files:

  • /conf/ocsci/live-must-gather.yaml - for usage of live GAed version of mus gather image
  • conf/ocsci/upstream-must-gather.yaml - for usage of upstream image, this is also now part of conf/deployment/ibmcloud/ibm_cloud_vpc_cluster.yaml

Deployment of OCP takes long time

It happened a lot that OCP cluster didn't get to normal state in several hours and was in warning status cause of some ingress issue. For now, the timeout is increased to 10 hours as a workaround.

Missing snapshotter CRDs

Some missing CRDs for snapshooter are missing in IBM Cloud. As a workaround we need to create those CRDs depends on OCP version. (this is covered in automation) OCP 4.6 https://github.com/openshift/csi-external-snapshotter/tree/release-4.6/client/config/crd OCP 4.5 https://github.com/openshift/csi-external-snapshotter/tree/release-4.5/config/crd

Requirements

  • Provide config file + credential config file described bellow to run-ci command via --ocsci-conf parameters.

Configuration files

  • conf/ocsci/openshift_dedicated.yaml - this file can be used for deployment on Openshift Dedicated.

You will need to create also credential file with secret data which should never be shared publicly in this repository. All needed values are mentioned as placeholders and commented out in conf/ocsci/openshift_dedicated.yaml and also mentioned below.

# This is the basic config for Openshift Dedicated usage

# be used
