fix dockertools.pullImage on darwin #41908

Motivation for this change

buildImage works, so I wanted to start using it.

The --override-{os,architecture} arguments are necessary for me, since skopeo's default behavior is to choose the manifest which matches the host system's os and architecture. For people on macs, this frequently doesn't exist, and is rarely what we want.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Fits CONTRIBUTING.md.

Could you add to describe a bit these arguments and the default behavior in the manual?
Otherwise, LGTM.

@nicknovitski I was actually more talking about describing these new arguments of dockerTools.pullImage in the description of this function in the manual. Sorry if I haven't been really clear:/ I was thinking to something such as:

(you can easily build the manual by running nix-build doc from the nixpkgs repository root directory).

I'm not sure I understand the failure, but it looks to me that like there's a nixos test for docker-tools, and some derivations it depends on failed to build. Is that right?

This looks good to me but I'm also not sure what the problem is with the test.

Might this make more sense as CGO_CFLAGS=$CFLAGS? and same with LDFLAGS. I think stdenv sets up the -I automatically for us in CFLAGS so this would mirror the buildInputs conditional logic more naturally.

What are you going to do with pullImage on Darwin?

@nicknovitski
Copy link
Contributor Author

Use it as an argument to buildImage. I've realized there isn't much I can do without cross-compilation, but, ehn, maybe I could try to make it work.

@puffnfresh

Contributor

@nicknovitski yeah, I've been working on https://github.com/nix-community/linuxkit-builder for this reason. Would love for my team to easily build Docker images using Nix on Darwin ❤️

@puffnfresh in my case I found this because I wanted to interact with a docker registry with skopeo from my Mac 😄and of course skopeo doesn't work on macOS without this PR

@copumpkin yeah, definitely no reason why Skopeo shouldn't work well on macOS.

Could a Darwin pullImage also be useful in isolation with Docker for Mac? I haven't really thought it through

@copumpkin should be able to docker load one, I think.
