Releasing Wanderer + keeping the ExApp in sync
Wanderer's version comes from git describe --tags (Makefile →
-ldflags -X main.Version). Tagging is the release act; a published
release also notifies the downstream Nextcloud ExApp
(MWest2020/wanderer-exapp) to rebuild its image pinned to the tag.
Cut a release
# 1. land the CHANGELOG: move [Unreleased] entries under a new
# [X.Y.Z] - <date> heading, leave an empty [Unreleased] on top.
# 2. tag + push
git tag -a vX.Y.Z -m "Wanderer vX.Y.Z"
git push origin vX.Y.Z
# 3. publish a GitHub release (this is what fires the ExApp sync)
gh release create vX.Y.Z --title "vX.Y.Z" --notes-from-tag
make build then reports vX.Y.Z via wanderer version.
One-time: the ExApp dispatch secret
The release-dispatch workflow calls repository_dispatch on
wanderer-exapp so it rebuilds against the new tag. The default
GITHUB_TOKEN cannot dispatch to another repo, so add a token
secret once:
- Create a token (either works):
- Classic PAT with the
reposcope, or - Fine-grained PAT scoped to
MWest2020/wanderer-exappwith Contents: Read and write (the permission GitHub'sPOST /repos/{owner}/{repo}/dispatchesendpoint requires).
GitHub → Settings → Developer settings → Personal access tokens.
- Store it as a secret on this repo (run it yourself — never paste a PAT into a tool):
sh
gh secret set EXAPP_DISPATCH_TOKEN --repo MWest2020/wanderer
# paste the token when prompted
Or via the UI: wanderer → Settings → Secrets and variables →
Actions → New repository secret → name EXAPP_DISPATCH_TOKEN.
That's it. On the next published release the workflow dispatches
event_type=wanderer-release with the tag; wanderer-exapp's
sync-wanderer workflow rebuilds + pushes
ghcr.io/mwest2020/wanderer-exapp:latest (+ core-<tag>).
Without the secret the workflow fails loudly with a clear message — it never silently no-ops.
Manual trigger (without a release)
gh workflow run release-dispatch.yml -f version=vX.Y.Z # this repo
# or directly on the downstream repo:
gh workflow run sync-wanderer.yml -f version=vX.Y.Z --repo MWest2020/wanderer-exapp
