Custom runtimes\nallow you to define new runtime environments, which might include additional\ncomponents like language interpreters or application servers.\n\nTo create a custom runtime, you create a Dockerfile with a base image of your\nchoice, and then add the `docker` commands that build your desired runtime\nenvironment. It's important to remember that you are responsible for ensuring\nthat the components that you specified in your Dockerfile are compatible and\nconfigured to deliver the desired performance.\n\nWhen you use a custom runtime, you must write your application code to handle\ncertain flexible environment life-cycle and health checking requests. Start by\nreading about how to [build a custom\nruntime](/appengine/docs/flexible/custom-runtimes/build) before you begin\ndeveloping your application.\n\nApplications that use custom runtimes take advantage of all the various\nGoogle Cloud services by using the public REST APIs or client libraries,\nsuch as the [App Engine Admin API](/appengine/docs/admin-api) and the [Google Client\nLibraries](/python/docs/reference).\n\nUse the following table to understand how a custom runtime compares to the\nexisting set of App Engine runtimes:\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e"]]
