I have a project which builds a rust and a node program into a docker container with a nix flake build. Here is my flake.nix. When I build it locally it takes a reasonable time to build, well under one minute.
Now to the actual problem I need help with: I have a GitHub action build pipeline which builds and publishes the container image. As of recent builds it takes a few hours to build the container image via
nix build. As you can see in the history of the runs, I haven’t changed anything related to the build when it started taking so long. Since I use a flake lock and a tagged version of the install nix action I am out of ideas where I should look for further clues.
Thanks in advance for ideas and help
