Introduction to Azure App Service on Linux

Azure App Service is a fully managed compute platform that is optimized for hosting websites and web applications. Customers can use App Service on Linux to host web apps natively on Linux for supported application stacks.


App Service on Linux supports a number of Built-in images in order to increase developer productivity. Languages include: Node.js, Java (JRE 8 & JRE 11), PHP, Python, .NET Core and Ruby. Run az webapp list-runtimes --linux to view the latest languages and supported versions. If the runtime your application requires is not supported in the built-in images, there are instructions on how to build your own Docker image to deploy to Web App for Containers.


  • FTP
  • Local Git
  • GitHub
  • Bitbucket


Console, Publishing, and Debugging

  • Environments
  • Deployments
  • Basic console
  • SSH


  • Customers can scale web apps up and down by changing the tier of their App Service plan


Check the Azure Status Dashboard.


The Azure portal shows only features that currently work for Web App for Containers. As we enable more features, they will become visible on the portal.

App Service on Linux is only supported with Free, Basic, Standard, Premium and Isolated app service plans and does not have a Shared tier. You cannot create a Linux Web App in an App Service plan already hosting non-Linux Web Apps.

Based on a current limitation, for the same resource group you cannot mix Windows and Linux apps in the same region.



There's new integrated logging capability with Azure Monitoring (preview) .

When your application fails to start or you want to check the logging from your app, check the Docker logs in the LogFiles directory. You can access this directory either through your SCM site or via FTP. To log the stdout and stderr from your container, you need to enable Application Logging under App Service Logs. The setting takes effect immediately. App Service detects the change and restarts the container automatically.

You can access the SCM site from Advanced Tools in the Development Tools menu.
