Situtaion

1. I push code to my repo on my self-hosted GitLab server.
2. It triggers my runner to run my CI job.
3. The CI job fails.
4. Now I want to go investigate the scene of the crime.

Question

How can I get into the Docker (container? image? volume?) and look around at what files the CI job had available when it failed? For instance, the job might have failed with a message like “check foo.log for details.” I have direct SSH access to the runner server, but I don’t know where to look or how to get into the Docker e.g. to inspect foo.log.
