Work with resources in the managed resource group for Azure managed application

  • Article

This article describes how to update resources that are deployed as part of a managed application. As the publisher of a managed application, you have access to the resources in the managed resource group. To update these resources, you need to find the managed resource group associated with a managed application, and access the resource in that resource group.

This article assumes you deployed the managed application in the Managed Web Application (IaaS) with Azure management services sample project. That managed application includes a Standard_D1_v2 virtual machine. If you didn't deploy that managed application, you can still use this article to become familiar with the steps for updating a managed resource group.

The following image shows the deployed managed application.

Deployed managed application

In this article, you use Azure CLI to:

  • Identify the managed application.
  • Identify the managed resource group.
  • Identify the virtual machine resource in the managed resource group.
  • Change the virtual machine size, either to a smaller size if not utilized, or a larger to support more load.
  • Assign a policy to the managed resource group that specifies the allowed locations.

Get managed application and managed resource group

To get the managed applications in a resource group, use:

az managedapp list --query "[?contains(resourceGroup,'DemoApp')]"

To get the ID of the managed resource group, use:

az managedapp list --query "[?contains(resourceGroup,'DemoApp')].{ managedResourceGroup:managedResourceGroupId }"

Resize VMs in managed resource group

To see the virtual machines in the managed resource group, provide the name of the managed resource group.

az vm list -g DemoApp6zkevchqk7sfq --query "[].{VMName:name,OSType:storageProfile.osDisk.osType,VMSize:hardwareProfile.vmSize}"

To update the size of the VMs, use:

az vm resize --size Standard_D2_v2 --ids $(az vm list -g DemoApp6zkevchqk7sfq --query "[].id" -o tsv)

After the operation completes, verify the application is running on Standard D2 v2.

Apply policy to managed resource group

Get the managed resource group and assignment a policy at that scope. The policy e56962a6-4747-49cd-b67b-bf8b01975c4c is a built-in policy for specifying allowed locations.

managedGroup=$(az managedapp show --name <app-name> --resource-group DemoApp --query managedResourceGroupId --output tsv)

az policy assignment create --name locationAssignment --policy e56962a6-4747-49cd-b67b-bf8b01975c4c --scope $managedGroup --params '{
                            "listofallowedLocations": {
                                "value": [
                                    "northeurope",
                                    "westeurope"
                                ]
                            }
                        }'

To see the allowed locations, use:

az policy assignment show --name locationAssignment --scope $managedGroup --query parameters.listofallowedLocations.value

The policy assignment appears in the portal.
