fix(monitoring): pin grafana-dashboards to an image that carries the mirrored plugins - #4477
IvanHunters wants to merge 3 commits into
Conversation
…mirrored plugins The committed grafana-dashboards ref was stamped at v1.6.0, two days before plugin mirroring landed, so its image has no /plugins directory. The chart's GF_INSTALL_PLUGINS installs those plugins from that in-cluster mirror at startup, so Grafana requests /plugins/grafana-worldmap-panel-1.0.6.zip, the mirror answers 404, and Grafana crashloops. Any render off the committed ref (a real install, or an E2E run that falls back to committed refs) hits it. Re-stamp to the v1.7.0-alpha.1 image, built from the identical Dockerfile and verified to serve all four requested plugin archives.

…e chart installs The Grafana plugin list is hand-maintained twice: the grafana-dashboards Dockerfile bakes /plugins/<id>-<ver>.zip, and grafana.yaml renders GF_INSTALL_PLUGINS pointing at the same names. When the two drift, Grafana asks the mirror for an archive it never built and crashloops. E2E does not reliably catch it, since a stacked PR overlays main's freshly built image. Parse both lists and fail when they differ, offline, at PR time. Refs: #4391 Assisted-by: LLM Signed-off-by: IvanHunters <[email protected]>

The header claimed the test guards the #4391 crashloop. It does not: #4391 was a stale image pin (the lists already agreed), and this test only compares the two source lists. Say so, and name the image-content check that would close the pin-drift class, so the comment stops overstating coverage. Refs: #4391 Assisted-by: LLM Signed-off-by: IvanHunters <[email protected]>

Reject partial producer-version matches.
If the Dockerfile changes a token to natel-discrete-panel:0.1.1-beta.1 while the chart still requests 0.1.1, this regex extracts only natel-discrete-panel:0.1.1. The test passes, but the image builds natel-discrete-panel-0.1.1-beta.1.zip and the chart requests natel-discrete-panel-0.1.1.zip. Parse complete tokens and fail on unsupported version formats instead of accepting a numeric prefix.

IvanHunters NOT LGTM. The tag change is a manual repin of a release-managed first-party ref, and the third commit message describes an earlier version of the PR.
Business context: Grafana crashloops on a 404 from the in-cluster plugin mirror whenever it runs with the committed grafana-dashboards ref, because that image was built before the plugins were added to it.
Blockers
B1: the grafana-dashboards.tag change bypasses release prep
This file is written only by make image (packages/system/grafana-operator/Makefile lines 20-21), and every commit that touched it on main since v1.3.0 is a Prepare release commit by cozystack-ci[bot]. docs/release.md says the digest-vendored Prepare release commit stays on the release line and does not land on main. So main keeps the last stable refs on purpose: every first-party ref on main is v1.6.0 today, not only this one. The new value is copied byte for byte from the alpha.1 staging commit 0b862c4 on release-1.7.0-alpha.1.
I checked the two broken paths the body names, and neither needs this commit. A real install gets its refs from a release. release-1.6 has no plugin mirroring (GF_INSTALL_PLUGINS is commented out in grafana.yaml there), and the alpha.1 line already pins this exact digest. The E2E fallback for stacked PRs was fixed by #4460, merged 2026-09-24.
The pinned image is also not a build of current main. It was built on 2026-09-02, and three dashboards it copies in changed since then (database-autoscaling, strimzi-kafka, virtual-machines). It also puts a pre-release tag on main, which docs/agents/image-refs.md treats as a defect on its own.
Fix: drop b5c3fd8. The ref gets refreshed by the next Prepare release. If main should carry fresh refs between releases, that is a change to the release model and needs its own proposal.
B2: commit 2c9e939 describes the previous version of the PR
Its body starts with "The header claimed the test guards the #4391 crashloop. It does not". This repo merges with merge commits, so the text lands in main, and it talks about a comment main never had. Fix: squash it into c66b8cd.
Non-blocking
- The parity test itself works. Changing
marcusolsson-dynamictext-panel:6.2.0to6.2.1in the Dockerfile makes it red with a clear diff, and setting the tag back to v1.6.0 keeps it green, as the header says. The CodeRabbit point on line 48 is real:6.2.0-beta.1in the Dockerfile against6.2.0in the chart also stays green, because the regex takes only the numeric prefix. Anchoring the version token to whitespace or end of line fixes it. - The header comment is 33 lines in a 99-line file. The #4391 paragraph is issue history, and the harness note repeats what
hack/cozytest.shalready documents, so both could go. - After B1, the title, body and release note need to change, since the PR body becomes the merge commit message. Something like
test(monitoring): check that the image and the chart list the same Grafana plugins.
I exported the v1.7.0-alpha.1 image: it has all four plugin archives under /var/www/dashboards/plugins. The problem is how the ref gets to main, not the image.

What this PR does
Grafana crashloops on startup whenever it renders off the committed
grafana-dashboardsimage ref: a real install, or an E2E run that falls back to committed refs (a stacked PR before #4460). The pinned image predates plugin mirroring, so it has no/plugins, andGF_INSTALL_PLUGINSgets a 404 on the first plugin. This is the grafana-dashboards half of #4391.packages/system/grafana-operator/images/grafana-dashboards.tagfrom thev1.6.0image (stamped 2026-07-22, two days before plugin mirroring landed in606ffd5b1) to thev1.7.0-alpha.1image, built from the identical Dockerfile and verified to serve all four archives the chart asks for (grafana-worldmap-panel-1.0.6,marcusolsson-dynamictext-panel-6.2.0,natel-discrete-panel-0.1.1,victoriametrics-logs-datasource-0.29.0).hack/grafana-dashboards-plugin-parity.bats: it parses the plugin list from both sides of the mirror (the Dockerfile that bakes/plugins/<id>-<ver>.zip, and theGF_INSTALL_PLUGINSthe chart renders) and fails when they drift. Nothing tied the two hand-maintained lists together before, and E2E can't be relied on to catch it since a stacked PR overlays main's freshly built image.make bats-unit-testspicks up the new file automatically; it passes here and reds on a one-version drift in either file.Refs #4391
