How to use ghcr.io/xtruder/nix-devcontainer in CI

[marionoxt]

Hi! Thanks for this project! It looks like it could be really useful for me! Let's say I want to run my tests in CI, but it shall be in the same docker container (for reproducibility) as the dev environment.

Just doing

runs-on: ubicloud-standard-4
container:
  image: ghcr.io/xtruder/nix-devcontainer
steps:
  ...

does not work and I get an error like this

Run actions/checkout@v4
/usr/bin/docker exec 7c3d2553128f2ceaf8fb81875b418aad7a3161c37e21f6b2a4a03dbc9e25a2a6 sh -c "cat /etc/*release | grep ^ID"
node:fs:2368
return binding.writeFileUtf8(
^

}

So it seems that this container is not suited for CI? I can use container: debian:12.1 but it would be nice if I could use the exact same container in CI and dev.
