* Widespread conflation of nix-channel, NIX_PATH and the hydra.nixos.org channels, all of which _can_ but probably shouldn't be called channels. * Relies on NIX_PATH which fundamentally does not support composition...

I think I've found the problem. @ofborg build postgresqlTestHook postgresqlTestHook.passthru.tests firefox-esr gnome3.zenity

Hmm, I didn't expect a mass rebuild, but like you say, I've changed the outcome of `lib.optionalString (substitutions != {})`. > To deprecate the `substitutions.passthru`, we'll have to correct all...

I think the most significant part of solving this is to improve `dockerTools` to add a streaming `mergeImages`, but the glue can also be improved on the arion side. The...

Yes, the flake comes with `nixosModules.arion` for this purpose. That's [this file](https://github.com/hercules-ci/arion/blob/master/nixos-module.nix).

That looks alright, but note that the password will be readable in the nix store.

While you can still technically use `docker-compose` with its own environment variable substitution, I wouldn't recommend it because that functionality may go away. I prefer to use module system abstractions...

That would be nice indeed. It seems to have both host and container parts. Systemd already runs in the container. The host is not really part of arion's scope. I...

With #117, arion becomes compatible with the podman runtime and since https://github.com/NixOS/nixpkgs/pull/123841 (not backported to 21.05 yet) you can use podman as an implementation of the docker socket. Perhaps this...

Tangentially related to #140, for those who are interested in adding arion projects immutably to a NixOS system as part of its configuration.
