What

Fixes the Flux OCI push targets emitted by the skaffold workflow generator so the repository value is no longer corrupted by YAML scalar folding.

  • The repo step now derives owner/name from GITHUB_REPOSITORY and emits the full OCI URL as steps.repo.outputs.repository.
  • build-render pushes to ghcr.io/<repo>/manifests/<repo>.
  • build-render-profile pushes to ghcr.io/<repo>/manifests/<profile> via the matrix MATRIX_NAME.
  • pkgs.fluxcd added to the skaffold devenv profile so flux is on PATH for the push action.

Why

pkgs.formats.yaml folds plain scalars over 80 columns and inserts a space at the break, which split the long inlined ${{ ... }} chain and produced a broken OCI reference. Computing the URL once in bash (a literal block scalar) and referencing a short output token removes the fold entirely.

📝 Walkthrough

Walkthrough

The Skaffold profile now includes pkgs.fluxcd. Standard and profile GitHub build-render jobs derive repository metadata inline, save Flux manifests, and conditionally run Flux push actions without the direnv-generated environment.

Changes

Skaffold Flux push integration

Layer / File(s) Summary
Flux push contracts and tooling
modules/devenv/integrations/github/skaffold.nix, modules/devenv/profiles/skaffold.nix
The workflow retains the flux-push option. The Skaffold profile adds pkgs.fluxcd.
Default workflow publishing
modules/devenv/integrations/github/skaffold.nix
The standard job derives the repository-named Flux manifest path from GITHUB_REPOSITORY. The Flux push step uses the saved manifest without the direnv-generated environment.
Profile workflow publishing
modules/devenv/integrations/github/skaffold.nix
Profile jobs derive the manifest path from matrix.name. The Flux push step uses the saved profile manifest without the direnv-generated environment.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e5d4a

The profile workflow can still publish incorrect Flux manifest content instead of the rendered profile manifest, affecting profile image publication. The PR should not merge until that correctness issue is corrected or explicitly accepted.

Write the rendered manifest contents.

The quoted here-document writes the literal $SKAFFOLD_MANIFEST. The flux-push step therefore reads an invalid manifest. Replace it with printf '%s' "$SKAFFOLD_MANIFEST" > artifacts/skaffold-manifest.yaml.

The flux-push step referenced steps.direnv.outputs.env, but the direnv
action writes to $GITHUB_ENV and exposes no outputs block, so the
reference was always empty. Remove it and inline the repo derivation
step that was previously factored into a repoStep helper.

Uppercase MATRIX_NAME env var in skaffold repo step

GitHub Actions step env keys are conventionally uppercase; align the inlined
repo step's env var with the rest of the workflow's output naming. No
behavioral change beyond the env key casing.
