Azure Container Apps, how can I set the "minimum replicas" to 2

On Azure Container Apps, you can configure scaling rules, including setting the minimum number of replicas to ensure that at least a certain number of instances are always running. Here's how you can set the "minimum replicas" value to 2 for your container app using the Azure CLI:

  1. Install the Azure CLI and ensure it’s up to date if you haven’t already:

    az upgrade

  2. Login to your Azure Account:

    az login

  3. Set the Azure subscription you want to use:

    az account set --subscription "YOUR_SUBSCRIPTION_ID"

  4. Update the container app configuration to set the minimum replicas.

Here’s an example command to update the existing container app configuration to set the minimum replicas to 2:

az containerapp update \
  --name <CONTAINER_APP_NAME> \
  --resource-group <RESOURCE_GROUP_NAME> \
  --set template.scale.minReplicas=2

Replace <CONTAINER_APP_NAME> with the actual name of your container app, and <RESOURCE_GROUP_NAME> with the name of the resource group containing your container app.

Verification

After updating, you can verify the current configuration by describing the container app:

az containerapp show \
  --name <CONTAINER_APP_NAME> \
  --resource-group <RESOURCE_GROUP_NAME>

Look for the template.scale.minReplicas field in the output to confirm it’s set to 2.
