You can install Azure Container Registry on Azure Stack Hub and make it available to your users so that they can host containers in your environment. To install Azure Container Registry, you must generate and validate a certificate, then install Azure Container Registry. You can install through the Azure Stack Hub administrator portal.

Important

Once installed, Azure Container Registry on Azure Stack Hub is considered a foundational RP and cannot be uninstalled. Operators can still restrict user access to the Container Registry service through offers, plans, and quotas.

Prerequisites

Azure Stack Hub version
You can only enable the Microsoft Azure Container in an Azure Stack Hub integrated system running the 2108 update and later releases. Install the Azure Stack Hub update before you complete the steps in this article. The Azure Container Registry service is not supported on the Azure Stack Developer Kit (ASDK) deployments.
Certificate requirements
The configuration of Azure Container Registry on your Azure Stack Hub system adds a new data path that requires a certificate. The certificate must meet the same requirements as the other certificates required to install and operate Azure Stack Hub.

The URI for this new certificate should have the following format:

*.azsacr.<region>.<fqdn>

For example:

*.azsacr.azurestack.contoso.com
Azure Stack Hub state
You should only install Azure Container Registry after validating that your Azure Stack Hub is healthy. You can do so by following the steps listed in Validate Azure Stack Hub system state.

Generate your certificate

You can use the following steps to generate an Azure Container Registry certificate using the Azure Stack Hub Readiness Checker tool. You must specify the version of the Microsoft.AzureStack.ReadinessChecker module for the steps to work.

Open PowerShell with an elevated prompt.

Run the following cmdlets:

Install-Module -Name Microsoft.AzureStack.ReadinessChecker 
New-Item -ItemType Directory "$ENV:USERPROFILE\Documents\AzsCertRequests"
    $certificateRequestParams = @{
        'regionName' = 'azurestack'
        'externalFQDN' = 'contoso.com'
        'subject' = "C=US,ST=Washington,L=Redmond,O=Microsoft,OU=Azure Stack"
        'OutputRequestPath' = "$ENV:USERPROFILE\Documents\AzsCertRequests" }
New-AzsHubAzureContainerRegistryCertificateSigningRequest @certificateRequestParams

When the ReadinessChecker module creates the .req file, sub the file to your Certificate Authority (CA) (either internal or public). The output directory of New-AzsCertificateSigningRequest contains the CSRs necessary to submit to a CA. For your reference, the directory also contains a child directory containing the INF files used during certificate request generation.

Validate the Azure Container Registry certificate

Validate that the Azure Container Registry certificate adheres to Azure Stack Hub requirements.

Copy resulting certificate file (.cer) signed by the CA (supported extensions .cer, .cert, .srt, .pfx) to $ENV:USERPROFILE\Documents\AzureStack.

Run the following PowerShell cmdlets from an elevated prompt:

Install-Module -Name Microsoft.AzureStack.ReadinessChecker 
$Path = "$ENV:USERPROFILE\Documents\AzureStack"
$pfxPassword = Read-Host -AsSecureString -Prompt "PFX Password"
ConvertTo-AzsPFX -Path $Path -pfxPassword $pfxPassword -ExportPath $Path

Installation steps

You can use these steps to install the Azure Container Registry service on Azure Stack Hub.

Portal

You can use the Azure Stack Hub administrator portal to import the certificate and install the service.

Sign into the Azure Stack Hub administrator portal.
Navigate to All Services > Container Registries.
Enter the full path to the SSL certificate.
Enter the password for the certificate.
Select Deploy.
