Comment PR test-build rebase command on each PR#8
Merged
Conversation
Adds a workflow that posts a one-time comment when a PR is opened with the signed rebase command for that PR's test image (pr-<number>-<image-version>). The image-version is read from the recipe so it survives Fedora bumps, and the tag is constant for the PR's lifetime so a single comment suffices.
🧪 Test this PR on a real installEach successful build of this PR publishes a signed test image to rpm-ostree rebase ostree-image-signed:docker://ghcr.io/mondrethos/monolith:pr-8-44
systemctl rebootThe tag is rebuilt on every new commit here, so rpm-ostree rebase ostree-image-signed:docker://ghcr.io/mondrethos/monolith:latestThe test tag stops updating once this PR is merged or closed. |
The comment posts when the PR opens, before the build has published the image. Phrase it so the reader waits for the green build check first, avoiding a manifest-not-found if the command is run too early.

.github/workflows/pr-rebase-hint.yml— posts a comment when a PR is opened with the exact rebase command for that PR's signed test image:Details
SIGNING_SECRET, so their images are cosign-signed (verifiedpr-7-44againstcosign.pub). The comment usesostree-image-signed:, matching the README; anyone testing is already on monolith and has the policy installed.image-versionis read fromrecipes/recipe.yml(currently44) so the tag stays correct across Fedora bumps.pr-N-<version>tag is constant for the PR's lifetime, so it posts once onopened/reopenedinstead of on every push.permissions: {}; the job takes onlycontents: readandpull-requests: write.Scope
Targets the current same-repo PR flow. Fork PRs (read-only token, unsigned image) are intentionally out of scope until outside contributions start.
Self-demo
This PR should get the comment on itself once the workflow runs.
