Create an ASP.NET Core app in a Docker container in App Service from Azure Container Registry

This sample script creates a resource group, a Linux App Service plan, and an app. It then deploys an ASP.NET Core application using a Docker Container from the Azure Container Registry.

If you don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

• Use the Bash environment in Azure Cloud Shell. For more information, see Quickstart for Bash in Azure Cloud Shell.

  

• If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

  • If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

  • When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

  • Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

Sample script

1. Create a resource group

   az group create --name myResourceGroup --location westus
   

2. Create an Azure Container Registry

   az acr create --name <registry_name> --resource-group myResourceGroup --location westus --sku basic --admin-enabled true --query loginServer --output tsv
   

3. Show ACR credentials

   az acr credential show --name <registry_name> --resource-group myResourceGroup --query [username,passwords[?name=='password'].value] --output tsv
   

4. Before continuing, save the ACR credentials and registry URL. You will need this information in the commands below.

5. Pull from Docker

   docker login <acr_registry_name>.azurecr.io -u <registry_user>
   docker pull <registry_user/container_name:version>
   

6. Tag Docker image

   docker tag <registry_user/container_name:version> <acr_registry_name>.azurecr.io/<container_name:version>
   

7. Push container image to Azure Container Registry

   docker push <acr_registry_name>.azurecr.io/<container_name:version>
   

8. Create an App Service plan

   az appservice plan create --name AppServiceLinuxDockerPlan --resource-group myResourceGroup --location westus --is-linux --sku S1
   

9. Create a web app

   az webapp create --name <app_name> --plan AppServiceLinuxDockerPlan --resource-group myResourceGroup --deployment-container-image-name <acr_registry_name>.azurecr.io/<container_name:version>
   

10. Configure an existing web app with a custom Docker Container from Azure Container Registry.

    az webapp config container set --resource-group myResourceGroup --name <app_name> --docker-registry-server-url http://<acr_registry_name>.azurecr.io --docker-registry-server-user <registry_user> --docker-registry-server-password <registry_password>
    

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup

Sample reference

This script uses the following commands to create a resource group, App Service app, and all related resources. Each command in the table links to command specific documentation.

Command	Notes
az group create	Creates a resource group in which all resources are stored.
az appservice plan create	Creates an App Service plan.
az webapp create	Creates an App Service app.
az webapp config container set	Sets the Docker container for the App Service app.
