Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either bash or PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.

To launch Azure Cloud Shell:

Option Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell. Example of Try It for Azure Cloud Shell
Go to https://shell.azure.com or select the Launch Cloud Shell button to open Cloud Shell in your browser.
Select the Cloud Shell button on the top-right menu bar in the Azure portal. Cloud Shell button in the Azure portal

To run the code in this article in Azure Cloud Shell:

  1. Launch Cloud Shell.
  2. Select the Copy button on a code block to copy the code.
  3. Paste the code into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS.
  4. Press Enter to run the code.

If you choose to install and use the CLI locally, you need Azure CLI version 2.0 or later. To find the version, run az --version. If you need to install or upgrade, see Install the Azure CLI.

Sample script

#/bin/bash

# Variables
appName="AppServiceLinuxDocker$random"
location="WestUS"
dockerHubContainerPath="<replace-with-docker-container-path>" #format: <username>/<container-or-image>:<tag>

# Create a Resource Group
az group create --name myResourceGroup --location $location

# Create an App Service Plan
az appservice plan create --name AppServiceLinuxDockerPlan --resource-group myResourceGroup --location $location --is-linux --sku S1

# Create a Web App
az webapp create --name $appName --plan AppServiceLinuxDockerPlan --resource-group myResourceGroup

# Configure Web App with a Custom Docker Container from Docker Hub
az webapp config container set --docker-custom-image-name $dockerHubContainerPath --name $appName --resource-group myResourceGroup

# Copy the result of the following command into a browser to see the web app.
echo http://$appName.azurewebsites.net
