Build locally, deploy on local, with `nom`:
|
|
|
|
sudo true && sudo nixos-rebuild test --flake . --recreate-lock-file --no-write-lock-file |& nom
|
|
|
|
Via git, build on remote:
|
|
|
|
ssh -t HOST sudo nixos-rebuild test --flake git+ssh://gitea@gitea.noximilien.pbsds.net/pbsds/nix-config.git --recreate-lock-file --no-write-lock-file
|
|
# or
|
|
ssh -t HOST sudo nixos-rebuild test --flake git+ssh://git@github.com/pbsds/nix-dotfiles.git --recreate-lock-file --no-write-lock-file
|
|
|
|
Via `remote-exec`, build on remote:
|
|
|
|
nix develop .#remote
|
|
remote-set FOOBAR
|
|
remote sudo nixos-rebuild test --flake . --recreate-lock-file --no-write-lock-file
|
|
|
|
From local checkout to remote where you're not a trusted user, via `tar` build on remote:
|
|
|
|
tar cf - --directory="$(nix eval --raw .#inputs.self.outPath)" . | ssh -tt HOST -- bash -c '"set -x; cd $(mktemp -d); tar xf - && nixos-rebuild test --flake . \"\$@\""' -- --print-build-logs --recreate-lock-file --no-write-lock-file
|
|
|
|
> TODO: ^ doesn't work, as tar consumes the stdin leaving sudo without one...
|
|
|
|
.. wait doesn't that litter `/tmp` or `/run/user/.../tmp`?
|
|
|
|
¯\_(ツ)_/¯
|
|
|
|
From local checkout to remote if local nix daemon has ssh keys, then build on remote:
|
|
|
|
nix copy --from "$(nix eval .#inputs.self.outPath)" --to TODO
|
|
|
|
Build locally, copy to remote

# How to evaluate the nixos flake/configuration.nix, checking if the drv hash is equal
|
|
|
|
Flakes:
|
|
|
|
nix eval .#nixosConfigurations.HOSTNAME.config.system.build.toplevel.outPath
|
|
|
|
Non-flake:
|
|
|
|
nix-instantiate '<nixpkgs/nixos>' -A system -I nixos-config=./configuration.nix
|
