build can not use dockerfiles out of the docker context

[jairov4]

skaffold build will complain with:

Error response from daemon: forbidden path outside the build context: ../platform/microservice/python3.9-poetry-microservice.dockerfile (). Docker build ran into internal error. Please retry.
If this keeps happening, please open an issue..

Expected behavior

Skaffold should be able to map the configuration to docker build my-app/ -f platform/microservice/python3.9-poetry-microservice.dockerfile (even not sure why skaffold is using dockerfile path relative to the context, the documentation says that it is relative to the workspace)

Actual behavior

Skaffold is failing complaining with an error message indicating the dockerfile is out of the docker context. But docker has not that limitation.

Information

• Skaffold version: v1.38.0
• Operating system: Centos 8
• Installed via: curl https://storage.googleapis.com/skaffold/releases/latest/skaffold-linux-amd64
• Contents of skaffold.yaml:

apiVersion: skaffold/v2beta11
kind: Config
build:
  artifacts:
    - image: my-app
      context: my-app
      docker:
        dockerfile: ../platform/microservice/python3.9-poetry-microservice.dockerfile

Steps to reproduce the behavior

1. create skaffold.yaml as provided, create the my-app folder
2. skaffold build

logs:

Unfortunately that is the design decision we took. Normally dockerfiles are kept closer to the code. Is there a reason why you have yours in a different directory?
