@conscious-puppet can you check if this PR solves your issue?

@shivaraj-bh process-compose does not get stuck now. but it if there is only one service, then it exits after running the init script. is there any way to display the error, if the exit code was non-zero?

[conscious-puppet]

just a suggestion, may be we can use this process compose option to prevent process-compose shutdown automatically

      --keep-project            keep the project running even after all processes exit

You can always do nix run .#<pc-project-name> -- --keep-project. Otherwise, there is also an option to run with --tui=false mode, so that the logs are dumped on the terminal’s stdout.

To configure in nix to use --keep-project will require contribution upstream in https://github.com/Platonic-Systems/process-compose-flake/blob/018783e68c89f94dbe11ce918d6206e9e4138787/nix/process-compose/cli.nix#L31-L73. I would propose to add one option extraCliArgs for such args instead of creating a specific option for it.
