How does Woodpecker start the container? (Can I make a login shell?)

[ndw]

I'm not sure if this is a CI question or a Docker question. I have a step that runs like this:

  - name: Build and test
    image: custom-build
    volumes:
      - custom-home:/home/builder
    commands:
      - whoami
      - echo $PATH

The container sets the user to "builder", and I can see that that is the user, but from the $PATH, it's clear that the builder's .bashrc hasn't been sourced. I can work around this with: bash -l -c "echo $PATH" but I wonder if I've overlooked something. (Or if I'm just doing it wrong.)

Addendum: it took me rather longer to find the source of this problem than I expected because:

docker run -it --rm --volume --volume custom-home:/home/builder custom-build

does seem to start a login shell. But maybe that's expected since it also gives me a shell prompt.

To get it right: Your container is rootless? And you would like to run the .bashrc before your commands are executed?

WP runs this as entrypoint: https://github.com/woodpecker-ci/woodpecker/blob/main/pipeline/backend/common/script.go#L31 (you can customize that with https://woodpecker-ci.org/docs/usage/workflow-syntax#entrypoint). Anything else is handled by the shell itself.
