forust 4f74fe1778 ci: stop inheriting the runner's python and node
The runner executes jobs on the host rather than in a container, so a
workflow that says 'python3' or 'npm' is really saying 'whatever this
machine happens to have today'. Both of the test jobs added in c00a472
were red on the first run for exactly that reason.

uv venv with no --python takes the first interpreter it finds, which is
the host's 3.14 here. pyrogram's sync.py calls the bare
asyncio.get_event_loop() that 3.14 no longer auto-creates, so three
tests died at collection. Pinned to 3.13, which is both what uv will
fetch when the host has none and what python:3.13-slim actually builds.

npm was missing outright, and turned up an hour later as npm 12 on node
26 - the same push, minutes apart. Neither is the panel image's
node:22-alpine, so node is now installed from the official tarball the
way the other tools are, at the image's major. npm is checked by running
it rather than by looking it up, so a name that resolves to something
broken reads as not installed.

Renovate keeps NODE_VERSION in step with the Dockerfile's node: tag, and
the two are one grouped dependency: CI that tests on a different major
than it builds on is a gate that can pass over a real break.

Renovate for Gitea

Renovate runs as a Kubernetes CronJob and creates container image update pull requests in Gitea. It does not deploy changes itself.

Kubernetes

Create a dedicated Gitea user named renovate-bot, create a repository access token, and grant it repository read/write plus issue read/write permissions. Add read:packages if Renovate must inspect private Gitea registry images.

Create the ignored Secret locally; never commit the PAT:

cp renovate/k8s/secrets.yaml.example renovate/k8s/secrets.yaml
$EDITOR renovate/k8s/secrets.yaml
kubectl apply -f renovate/k8s/namespace.yaml
kubectl apply -f renovate/k8s/secrets.yaml
kubectl apply -f renovate/k8s/configmap.yaml
kubectl apply -f renovate/k8s/cronjob.yaml

The renovate/k8s/active marker makes the normal deployment workflow include the namespace, ConfigMap, and CronJob. The Secret is intentionally excluded from Git and must be applied separately after every new cluster.

Run it immediately instead of waiting for the six-hour schedule.

Two options, both use the same renovate/renovate.json:

kubectl create job --from=cronjob/renovate renovate-manual-$(date +%s) -n renovate

or the renovate-run Actions workflow (Actions tab → renovate-run → Run workflow). It runs the same image as the CronJob on the self-hosted runner via Docker — the tag is read out of renovate/k8s/cronjob.yaml at run time rather than hardcoded, so the two cannot drift apart. Required Actions secrets (repo or org settings):

  • RENOVATE_TOKEN — renovate-bot PAT (repository + issue read/write).
  • RENOVATE_GITHUB_COM_TOKEN — optional, for changelogs and GitHub rate limits.

Inputs: repositories (default forust/homelab), log_level (info/debug). Only one run at a time (concurrency group renovate-run), same as the CronJob Forbid policy.

Inspect runs with:

kubectl get cronjob,jobs,pods -n renovate
kubectl logs -n renovate job/<job-name>

RENOVATE_GITHUB_COM_TOKEN is optional but recommended for changelogs and GitHub API rate limits. Set it in the Kubernetes Secret if available.

Compose

Copy .env.example to .env, set the PAT, and run:

docker compose -f renovate-compose.yaml run --rm renovate

The Compose file is intentionally named renovate-compose.yaml, so the repository's automatic deployment discovery does not start it accidentally.

Configuration

renovate/renovate.json is the single source of truth. The Compose file and the renovate-run workflow mount that file directly.

A ConfigMap cannot read from the repository, so the CronJob needs the config inlined. renovate/k8s/configmap.yaml is therefore a generated copy:

.gitea/workflows/sync-renovate-configmap.sh          # regenerate after editing
.gitea/workflows/sync-renovate-configmap.sh --check  # fail if out of date

The renovate-ci workflow runs the --check form on every PR and push, so a config edit that forgets to regenerate the ConfigMap cannot be merged.

Beyond images, customManagers in the config track:

  • Helm chart versions pinned in .gitea/workflows/deploy-lib.sh. The built-in helmv3 manager only reads Chart.yaml and helm-values only reads values files, so neither sees a version written into a helm upgrade command — these are declared as custom.regex managers against the helm datasource.
  • CI linter versions in .gitea/workflows/tool-versions.env.

The Renovate image tag is deliberately not in tool-versions.env: renovate/k8s/cronjob.yaml owns it, and the workflows read it from there.

How updates flow

Renovate scans both compose.yaml files and Kubernetes manifests, opens a branch and PR with image tag changes, and waits for CI. After merge, the existing deployment workflow applies Kubernetes changes or redeploys Compose stacks. Renovate never updates running workloads directly.
