Create an ASP.NET Core app in a Docker container from Docker Hub using Azure CLI
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.
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.
Launch Azure Cloud Shell
The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.
To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.
When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.
Sign in to Azure
Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing
<Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.
subscription="<subscriptionId>" # add subscription here az account set -s $subscription # ...or use 'az login'
To create the web app
# Create an ASP.NET Core app in a Docker container from Docker Hub # set -e # exit if error # Variable block let "randomIdentifier=$RANDOM*$RANDOM" location="East US" resourceGroup="msdocs-app-service-rg-$randomIdentifier" tag="deploy-linux-docker-app-only.sh" appServicePlan="msdocs-app-service-plan-$randomIdentifier" webapp="msdocs-web-app-$randomIdentifier" # Create a resource group. echo "Creating $resourceGroup in "$location"..." az group create --name $resourceGroup --location "$location" --tag $tag # Create an App Service plan in S1 tier echo "Creating $appServicePlan" az appservice plan create --name $appServicePlan --resource-group $resourceGroup --sku S1 --is-linux # Create a web app. To see list of available runtimes, run 'az webapp list-runtimes --linux' echo "Creating $webapp" az webapp create --name $webapp --resource-group $resourceGroup --plan $appServicePlan --runtime "NODE|14-lts" # Copy the result of the following command into a browser to see the static HTML site. site="http://$webapp.azurewebsites.net" echo $site curl "$site"
Configure Web App with a Custom Docker Container from Docker Hub
Create the following variable containing your GitHub information.
dockerHubContainerPath="<replace-with-docker-container-path>" #format: <username>/<container-or-image>:<tag>
Configure the web app with a custom docker container from Docker Hub.
az webapp config container set --docker-custom-image-name $dockerHubContainerPath --name $webApp --resource-group $resourceGroup
Copy the result of the following command into a browser to see the web app.
site="http://$webapp.azurewebsites.net" echo $site curl "$site"
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
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.
||Creates a resource group in which all resources are stored.|
||Creates an App Service plan.|
||Creates an App Service app.|
||Sets the Docker container for the App Service app.|
For more information on the Azure CLI, see Azure CLI documentation.
Additional App Service CLI script samples can be found in the Azure App Service documentation.
