Setting Up the OpenShift Container Platform CLI Environment

Prerequisites

• Azure subscription. You need to have access to Azure portal
• Install the Azure CLI
• Install OpenShift CLI

Create an Azure Red Hat OpenShift 4 cluster

• Login to Azure CLI

az login

• Register the resource provider

az provider register -n Microsoft.RedHatOpenShift --wait

• Create virtual network
  • Set the following variable

    LOCATION=eastus           # the location of your cluster
    RESOURCEGROUP=aro-rg      # the name of the resource group where you want to create your cluster
    CLUSTER=cluster           # the name of your cluster
    

• Create a resource group

az group create --name $RESOURCEGROUP --location $LOCATION

• Create a virtual network

  az network vnet create \
  --resource-group $RESOURCEGROUP \
  --name aro-vnet \
  --address-prefixes 10.0.0.0/22

• Add an empty subnet for the master nodes

  az network vnet subnet create \
  --resource-group $RESOURCEGROUP \
  --vnet-name aro-vnet \
  --name master-subnet \
  --address-prefixes 10.0.0.0/23 \
  --service-endpoints Microsoft.ContainerRegistry

• Add an empty subnet for the worker nodes

  az network vnet subnet create \
  --resource-group $RESOURCEGROUP \
  --vnet-name aro-vnet \
  --name worker-subnet \
  --address-prefixes 10.0.2.0/23 \
  --service-endpoints Microsoft.ContainerRegistry

• Disable subnet private endpoint policies. This is required to connect and manage the cluster

  az network vnet subnet update \
  --name master-subnet \
  --resource-group $RESOURCEGROUP \
  --vnet-name aro-vnet \
  --disable-private-link-service-network-policies true

Create the cluster

Create the cluster using following command. This may take around ~30 mins to create a cluster.

  az aro create \
   --resource-group $RESOURCEGROUP \
   --name $CLUSTER \
   --vnet aro-vnet \
   --master-subnet master-subnet \
   --worker-subnet worker-subnet

Connect to Cluster

• Get login credentials of the OpenShift cluster you have created in the previous step.
  Run following command:

  az aro list-credentials \
   --name $CLUSTER \
   --resource-group $RESOURCEGROUP

• Get the cluster console URL.

  az aro show \
   --name $CLUSTER \
   --resource-group $RESOURCEGROUP \
   --query "consoleProfile.url" -o tsv

• Launch the console URL in a browser and login using the credentials obtained in the step-1.

• Access cluster

apiServer=$(az aro show -g $RESOURCEGROUP -n $CLUSTER --query apiserverProfile.url -o tsv)
oc login $apiServer -u kubeadmin -p <kubeadmin password>
