Builds keep failing intermittently

My builds keep failing with the following error

#26 63.72 ** (Mix) Could not compile dependency :idna, "/root/.mix/rebar3 bare compile --paths /app/_build/prod/lib/*/ebin" command failed. You can recompile this dependency with "mix deps.compile idna", update it with "mix deps.update idna" or clean it with "mix deps.clean idna"

I think this is similar to a problem that occurred a few months back and described here: The CI/CD Pipeline suddenly fails without any changes done to the repository

It was resolved by one of the responders pinning docker to a slightly older commit hash:

  image: docker@sha256:c8bb6fa5388b56304dd770c4bc0478de81ce18540173b1a589178c0d31bfce90

    - name: docker:dind@sha256:c8bb6fa5388b56304dd770c4bc0478de81ce18540173b1a589178c0d31bfce90
  stage: docker

Is this problem recurring? How do I find the sha hash for an older image?

Can you provide more information?

  • contents of gitlab-ci.yml
  • which type of runner are you using?
  • the whole output of the pipeline
