This module is a wrapper module that groups the following modules:
- base-ocp-vpc-module - Provisions a base (bare) Red Hat OpenShift Container Platform cluster on VPC Gen2 (supports passing Key Protect details to encrypt cluster).
- observability-agents-module - Deploys Log Analysis and Cloud Monitoring agents to a cluster.
âť— Important: You can't update Red Hat OpenShift cluster nodes by using this module. The Terraform logic ignores updates to prevent possible destructive changes.
- Make sure that you have a recent version of the IBM Cloud CLI
- Make sure that you have a recent version of the IBM Cloud Kubernetes service CLI
