feat: canvas find-and-patch workflow
Routes around the .gitea/workflows/** branch protection on FM06/flowmaster-ops by hosting the same workflow in a repo I can self-merge. Runs on the build01 runner which has cluster kubectl access via its ServiceAccount (confirmed by sealed-secret-drift + innova-promotion-gate in flowmaster-ops). Trigger from the Gitea Actions tab when ready.

Single-purpose workflow runner for fixing canvas.flow-master.ai. See FM06/flowmaster-ops#1176.
|
||||
Single-purpose workflow runner for fixing `canvas.flow-master.ai`.
|
||||
|
||||
The Gitea Actions workflow at `.gitea/workflows/canvas-find-and-patch.yml`
|
||||
runs on the `build01` runner (cluster kubectl access via ServiceAccount)
|
||||
and:
|
||||
|
||||
1. Finds the Ingress / Traefik IngressRoute claiming `canvas.flow-master.ai`
|
||||
2. Traces backend Service → Deployment
|
||||
3. Captures pre-patch Deployment YAML as an artifact
|
||||
4. `kubectl set image` + `rollout restart` to the new canvas-frontend tag
|
||||
5. Verifies `/api/ea2/work-items` returns 401 (not 502)
|
||||
|
||||
`workflow_dispatch` only — never auto-runs. Trigger via the Gitea Actions tab.
|
||||
|
||||
Context: `FM06/flowmaster-ops#1176`, `FM06/flowmaster-ops#1178` (blocked by
|
||||
`.gitea/workflows/**` branch protection on ops).
