Service Images for GitLab CI
This repository stores commonly used Docker images, fixed for working within GitLab CI.
GitLab CI/CD pipelines fail to healthcheck service containers that expose more than one port, like DinD and others (see related issues).
We fix that by building from scratch to remove exposed ports in upstream images,
and exposing only one port.
To copy original image's metadata (ENV, ENTRYPOINT and others) use docker inspect.
