Introduction

The playbooks are used for installation of OCP on Power and other post install customizations. The playbooks are used with the following projects 1 and 2

Assumptions

• A bastion/helper node is already created where the playbooks would run.
• The required services are configured on the bastion/helper node eg: HTTP, HAProxy, DNS, DHCP, etc.
• The cluster nodes are already created.

Set up the required variables

Make use of the sample file at examples/install_vars.yaml. Modify the values as per your cluster.

cp examples/install_vars.yaml .

Use install_vars.yaml

This section sets the variables for the install-config.yaml template file.

install_config:
   cluster_domain: < Cluster domain name. Match to the baseDomain in install-config.yaml.>
   cluster_id: < Cluster identifier. Match to the metadata.name in install-config.yaml.>
   pull_secret: '<pull-secret json content>'
   public_ssh_key: '<SSH public key content to access the cluster nodes>'

Below variables will be used by the OCP install playbook.

workdir: <Directory to use for creating OCP configs>
storage_type: <Storage type used in the cluster. Eg: nfs (Note: Currently NFS provisioner is not configured using this playbook. This variable is only used for setting up image registry to EmptyDir if storage_type is not nfs)>
log_level: <Option --log-level in openshift-install commands. Default is 'info'>
release_image_override: '<This is set to OPENSHIFT_INSTALL_RELEASE_IMAGE_OVERRIDE while creating ign files. If you are using internal artifactory then ensure that you have added auth key to the pull_secret>'
rhcos_kernel_options: <List of kernel options for RHCOS nodes eg: ["slub_max_order=0","loglevel=7"]>

Setting up inventory

Make use of sample file at examples/inventory. Modify the host values as per your cluster.

cp examples/inventory .

Run the playbook

Once you have configured the vars & inventory file, run the install playbook using:

ansible-playbook  -i inventory -e @install_vars.yaml playbooks/install.yaml
