What is ARO
Azure Red Hat OpenShift (ARO) is a fully-managed service of Red Hat OpenShift on Azure, Jointly engineered, managed, and supported by Microsoft and Red Hat.
Prerequisites
- Azure account with portal access
- Make sure your Azure User account has
Microsoft.Authorization/roleAssignments/writepermissions, such asUser Access AdministratororOwnermore info here
The default Azure resource quota for a new Azure subscription is 10 and does not meet this requirement. Increase quota from 10 to minimum 40 by following this guide
Launch Azure Cloud Shell from Azure Portal (top right).
Export some variables that we will often use in the rest of the tutorial.
export LOCATION=centralindia
export RESOURCEGROUP=ksingh-resource-group-india
export CLUSTER=azureopenstack
- Verify the quota
az vm list-usage -l $LOCATION \
--query "[?contains(name.value, 'standardDSv3Family')]" \
-o table
- Grab subscription ID from Azure Portal
az account set --subscription <SUBSCRIPTION ID>
Launching ARO Cluster
# Register the resource providers
az provider register -n Microsoft.RedHatOpenShift --wait
az provider register -n Microsoft.Compute --wait
az provider register -n Microsoft.Storage --wait
az provider register -n Microsoft.Authorization --wait
# 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
# Create two subnets in aro-vnet network for OpenShift control plane (master) and worker 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
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
# Update master node subnet network policy
az network vnet subnet update --name master-subnet --resource-group $RESOURCEGROUP --vnet-name aro-vnet --disable-private-link-service-network-policies true
# Finally, create ARO cluster with default configuration
az aro create --resource-group $RESOURCEGROUP --name $CLUSTER --vnet aro-vnet --master-subnet master-subnet --worker-subnet worker-subnet
Connect to ARO
- (GUI) Grab OpenShift Console URL and credentials
az aro show --name $CLUSTER --resource-group $RESOURCEGROUP --query "consoleProfile.url" -o tsv
az aro list-credentials --name $CLUSTER --resource-group $RESOURCEGROUP
- (CLI) Install OpenShift Client
oc
cd ~
wget https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/openshift-client-linux.tar.gz
mkdir openshift
tar -zxvf openshift-client-linux.tar.gz -C openshift
echo 'export PATH=$PATH:~/openshift' >> ~/.bashrc && source ~/.bashrc
apiServer=$(az aro show -g $RESOURCEGROUP -n $CLUSTER --query apiserverProfile.url -o tsv)
oc login $apiServer -u kubeadmin -p <kubeadmin password>
Summary
The experience of launching OpenShift cluster from Azure Cloud Shell aro is very simple and easy.
Hope this guide helps you, See You Next Time o/
