Introduction to Azure App Service on Linux
Web App 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. The following sections lists the application stacks that are currently supported.
Languages
App Service on Linux supports a number of Built-in images in order to increase developer productivity. 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.
| Language | Supported Versions |
|---|---|
| Node.js | 4.4, 4.5, 4.8, 6.2, 6.6, 6.9, 6.10, 6.11, 8.0, 8.1, 8.2, 8.8, 8.9, 8.11, 9.4, 10.1,10.10 |
| Java * | Tomcat 8.5, 9.0, Java SE, WildFly 14 (all running JRE 8) |
| PHP | 5.6, 7.0, 7.2 |
| Python (Preview) | 3.6, 3.7 |
| .NET Core | 1.0, 1.1, 2.0, 2.1 |
| Ruby | 2.3 |

Limitations
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.
Some features, such as virtual network integration, Azure Active Directory/third-party authentication, or Kudu site extensions, are not available yet. Once these features are available, we will update our documentation and blog about the changes.
App Service on Linux is only supported with Basic, Standard, and Premium app service plans and does not have a Free or Shared tier. You cannot create Web App for Containers in an App Service plan already hosting non-Linux Web Apps. There is a current limitation in regards to not mixing Windows and Linux apps in the same resource group as well.
Troubleshooting
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 Docker Container logging under Diagnostics Logs.
You can access the SCM site from Advanced Tools in the Development Tools menu.
