Quickstart: Deploy an Azure Red Hat OpenShift cluster with an Azure Resource Manager template or Bicep file

  • Article

This quickstart describes how to use either Azure Resource Manager template (ARM template) or Bicep to create an Azure Red Hat OpenShift cluster. You can deploy the Azure Red Hat OpenShift cluster with either PowerShell or the Azure command-line interface (Azure CLI).

An Azure Resource Manager template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax. You describe your intended deployment without writing the sequence of programming commands to create the deployment.

Bicep is a domain-specific language (DSL) that uses declarative syntax to deploy Azure resources. In a Bicep file, you define the infrastructure you want to deploy to Azure, and then use that file throughout the development lifecycle to repeatedly deploy your infrastructure. Your resources are deployed in a consistent manner.

Prerequisites

Create an ARM template or Bicep file

Choose either an Azure Resource Manager template (ARM template) or an Azure Bicep file. Then, you can deploy the template using either the Azure command line (azure-cli) or PowerShell.

Create an ARM template

The following example shows how your ARM template should look when configured for your Azure RedHat OpenShift cluster.

The template defines three Azure resources:

More Azure Red Hat OpenShift template samples can be found on the Red Hat OpenShift web site.

Save the following example as azuredeploy.bicep:

Create a Bicep file

The following example shows how your Azure Bicep file should look when configured for your Azure Red Hat OpenShift cluster.

The Bicep file defines three Azure resources:

More Azure Red Hat OpenShift templates can be found on the Red Hat OpenShift web site.

Create the following Bicep file containing the definition for the Azure Red Hat OpenShift cluster. The following example shows how your Bicep file should look when configured.

The following sections provide instructions using PowerShell or Azure CLI.

PowerShell steps

Perform the following steps if you're using PowerShell.

Before you begin - PowerShell

Before running the commands in this quickstart, you might need to run Connect-AzAccount. Check to determine whether you have connectivity to Azure before proceeding. To check whether you have connectivity, run Get-AzContext to verify whether you have access to an active Azure subscription.

Note

This template uses the pull secret text that was obtained from the Red Hat OpenShift Cluster Manager website. Before proceeding, ensure you have the pull secret saved locally as pull-secret.txt.

$rhosPullSecret= Get-Content .\pull-secret.txt -Raw # the pull secret text that was obtained from the Red Hat OpenShift Cluster Manager website

Define the following parameters as environment variables - PowerShell

$resourceGroup="aro-rg"	     # the new resource group for the cluster
$location="eastus"    		 # the location of the new ARO cluster
$domain="mydomain"           # the domain prefix for the cluster  
$aroClusterName="cluster"    # the name of the cluster

Register the required resource providers - PowerShell

Register the following resource providers in your subscription: Microsoft.RedHatOpenShift, Microsoft.Compute, Microsoft.Storage and Microsoft.Authorization.

Register-AzResourceProvider -ProviderNamespace Microsoft.RedHatOpenShift
Register-AzResourceProvider -ProviderNamespace Microsoft.Compute
Register-AzResourceProvider -ProviderNamespace Microsoft.Storage
Register-AzResourceProvider -ProviderNamespace Microsoft.Authorization

Create the new resource group - PowerShell

New-AzResourceGroup -Name $resourceGroup -Location $location

Create a new service principal and assign roles - PowerShell

$suffix=Get-Random # random suffix for the Service Principal
$spDisplayName="sp-$resourceGroup-$suffix"
$azureADAppSp = New-AzADServicePrincipal -DisplayName $spDisplayName -Role Contributor

New-AzRoleAssignment -ObjectId $azureADAppSp.Id -RoleDefinitionName 'User Access Administrator' -ResourceGroupName $resourceGroup -ObjectType 'ServicePrincipal'
New-AzRoleAssignment -ObJectId $azureADAppSp.Id -RoleDefinitionName 'Contributor' -ResourceGroupName $resourceGroup -ObjectType 'ServicePrincipal'

Get the Service Principal password - PowerShell

$aadClientSecretDigest = ConvertTo-SecureString -String $azureADAppSp.PasswordCredentials.SecretText -AsPlainText -Force

Get the service principal for the OpenShift resource provider - PowerShell

$rpOpenShift =  Get-AzADServicePrincipal -DisplayName 'Azure Red Hat OpenShift RP' | Select-Object -ExpandProperty Id -Property Id -First 1

Check the parameters before deploying the cluster - PowerShell

# setup the parameters for the deployment
$templateParams = @{  
    domain = $domain
    clusterName = $aroClusterName
    location = $location
    aadClientId = $azureADAppSp.AppId
    aadObjectId = $azureADAppSp.Id
    aadClientSecret = $aadClientSecretDigest 
    rpObjectId = $rpOpenShift.Id
    pullSecret = $rhosPullSecret
}

Write-Verbose (ConvertTo-Json $templateParams) -Verbose

Deploy the Azure Red Hat OpenShift cluster using the ARM template - PowerShell

New-AzResourceGroupDeployment -ResourceGroupName $resourceGroup @templateParams `
    -TemplateFile azuredeploy.json

Connect to your cluster

To connect to your new cluster, review the steps in Connect to an Azure Red Hat OpenShift 4 cluster.
