Description

Allow users to refer the requirements.txt file in runtime_env from the zipfile provided as working_dir.

Use case

Allowing users to refer the requirements.txt file in runtime_env from the zipfile provided as working_dir, will be convenient to package the app with their requirements rather than having to enumerate each dependency in the pip section. Having to enumerate each dependency one by one can get unwieldy.

I like to use the compiled requirements created by using pip-tools to pin each dependency. So having that in a file would be convenient as well as keep the yaml file short.

apiVersion: ray.io/v1alpha1
kind: RayService
metadata:
  name: rayservice-sample
spec:
  serveConfigV2: |
    applications:
      - name: text_ml_app
        import_path: text_ml.app
        route_prefix: /summarize_translate
        runtime_env:
          working_dir: "s3://bucket/path/app.zip"
          pip:
            - "./requirements.txt" # This will be from the app.zip
