docker-cmd-file not working

[lazytesting]

This issue is maybe related to #794 but that one does not contains a solution and I still got a stable reproduction scenario.

1. In the action config file I set:

 with:
          docker-cmd-file: example/entrypoint.sh

2. In the logs I see

/usr/bin/docker run --env LOG_LEVEL --env RENOVATE_TOKEN=*** --env RENOVATE_CONFIG_FILE=/github-action/renovate-config.js --volume /home/runner/work/test-renovate/test-renovate/example/renovate-config.js:/github-action/renovate-config.js --volume /home/runner/work/test-renovate/test-renovate/example/entrypoint.sh:/entrypoint.sh --user root --volume /tmp:/tmp --rm ghcr.io/renovatebot/renovate:37.175.3 /entrypoint.sh
...some unrelevant log lines...
DEBUG: CLI config "config": {"repositories": ["/entrypoint.sh"]}

3. It seems that the /entrypoint.sh argument for docker run is not running the custom entrypoints script
4. I think renovate gets called with this argument, like this:

renovate /entrypoint.sh

this would explain why it sees a cli config with this value als repositories at least.

I took the examples from this project and stripped it down to a minimal reproduction path.
code: https://github.com/lazytesting/test-renovate
action run: https://github.com/lazytesting/test-renovate/actions/runs/7829422258/job/21361374380

The strange thing is that it seems to work in the e2e test github action of this project but I cannot see the difference.

I'm pretty sure it this test which fails: https://github.com/renovatebot/docker-renovate/blob/e0c1bdc511c5c7e912f2b45a669be07447e52cdd/bin/docker-entrypoint.sh#L13

This needs a community contribution to fix, because we don't use this.

Happy to contribute but I lack a bit of context. What I don't understand is why that file gets called, I would expect that it gets overriden with the docker-cmd-file setting or do I miss something?

I don't really know whats going wrong, but here is a working example on our ci

github-action/.github/workflows/build.yml

Line 104 in fd4ca43

docker-cmd-file: example/entrypoint.sh

Finally found it... it was the execution permission after all. I did set them but not in the correct way...

If you like it, I with the following changes:

• add the executable part to the documentation
• add a validation that the file is executable

sure, go ahead
