Installation

Prerequisites

• Install Azure CLI, as shown here: Azure CLI | Installation.
• Azure Red Hat OpenShift requires a minimum of 40 cores. May need to increase the quota.

Procedure

Create the Resource Group

The resource group can be created from the console, and it will encapsulate resources required by, and dedicated to the OpenShift cluster. The name of the resource group should be derived from the name of the cluster by adding the "-rg" postfix. There will be a one-to-one relationship between the resource group, cluster and ancillary resources. Select the appropriate region and set the corresponding LOCATION environment variable.

export CLUSTER=platform-cloud-aro-01
export RESOURCEGROUP="${CLUSTER}-rg"
export LOCATION=eastus2

Register Resource Providers

export SUBSCRIPTION_ID="..."
az account set --subscription ${SUBSCRIPTION_ID}

Register the Microsoft.RedHatOpenShift, Microsoft.Compute and Microsoft.Storage resource providers:

az provider register -n Microsoft.RedHatOpenShift --wait
az provider register -n Microsoft.Compute --wait
az provider register -n Microsoft.Storage --wait
