Mikado chain to upgrade Grafana from 11.4.0 (Helm chart) to 12.x with:

  • Home-built Nix container image (forge.ops.eblu.me/eblume/grafana)
  • Kustomize manifests replacing the Helm chart
  • Single-source ArgoCD app

Chain

Goal: upgrade-grafana
Leaves: build-grafana-container, kustomize-grafana-deployment

Track with: mise run docs-mikado upgrade-grafana

Test plan

Add home-built Grafana 12.3.3 container image based on Alpine 3.22
with pre-built OSS tarball from dl.grafana.com. Uses UID 472 for PVC
compatibility with the official image, standard Grafana paths, and
multi-arch support via TARGETPLATFORM detection.

Update service-versions.yaml to track 12.3.3.

Home-built Grafana 12.3.3 container is ready. Dockerfile builds from
Alpine 3.22 + official OSS tarball, verified via dagger and
container-version-check.

Replace Helm chart with plain kustomize manifests:
- deployment.yaml: Grafana 12.3.3 (home-built) + k8s-sidecar + init container
- configmap.yaml: grafana.ini (Authentik OIDC, datasources, paths)
- service.yaml, pvc.yaml, serviceaccount.yaml, rbac.yaml
- ArgoCD app converted from Helm multi-source to single kustomize source
- Removed Helm values.yaml
