How to create ARO(Azure Redhat OpenShift) private cluster

Register to azure redhat 

az account set --subscription 7ce96666-9c91-4251-a956-c0bbc4617409 

az provider register -n Microsoft.RedHatOpenShift --wait 

az provider register -n Microsoft.Compute --wait 

az provider register -n Microsoft.Network --wait 

az provider register -n Microsoft.Storage --wait 

 Envirinment variables: 

LOCATION=eastus # the location of your cluster 

RESOURCEGROUP="v4-$LOCATION" # the name of the resource group where you want to create your cluster 

CLUSTER=aro-cluster # the name of your cluster 

 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 on the master subnet. This is required to be able 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 Check accessability
