## Summary
C2 Mikado chain to move the entire Immich stack (server, ML, valkey,
postgres) off `minikube-indri` and onto `k3s-ringtail`. Immich is the
largest single tenant on minikube (~1.5 GiB resident) and minikube is
currently memory-saturated (97% RAM, swapping). This is the first
concrete chain in the broader indri-k8s decommission effort.
This PR contains the planning layer only — 7 cards (1 goal + 6
prerequisites). Implementation cycles follow per the Mikado Branch
Invariant.
## Goal end-state
- Immich `server`, `machine-learning`, `valkey` on ringtail.
- ML pod uses ringtail's RTX 4080 (performance win — currently
CPU-only).
- CNPG `immich-pg` (PG17 + VectorChord) runs on ringtail.
- Library still on sifaka NFS — ringtail mounts the same path.
- `photos.ops.eblu.me` reroutes through Caddy → ringtail ingress.
- Minikube `immich` and `immich-pg` are removed.
## Cards
| Card | Depends on |
|---|---|
| `migrate-immich-to-ringtail` (goal) | all six below |
| `cnpg-on-ringtail` | — |
| `immich-pg-on-ringtail` | cnpg-on-ringtail |
| `immich-pg-data-migration` | immich-pg-on-ringtail |
| `sifaka-nfs-from-ringtail` | — |
| `immich-app-on-ringtail` | immich-pg-on-ringtail, sifaka-nfs-from-ringtail |
| `immich-cutover-and-decommission` | immich-pg-data-migration, immich-app-on-ringtail |
## Key constraints
- **No data loss.** Downtime is acceptable; data loss is not. Two
surfaces matter: postgres (ML embeddings, face data — slow to
re-derive) and the library files (don't move, but NFS access from
ringtail must be verified).
- **Migration method:** Option A is a CNPG `externalCluster`
basebackup → promote. Option B is `pg_dump`/`pg_restore` as a
documented fallback. Either way, dry-run against a scratch
cluster first.
- **Why pg moves too** (not cross-cluster): keeping pg on minikube
would block the whole decommission, and Immich is chatty with pg
so tailnet round-trips would hurt.
## Test plan
- [ ] Plan review — does the dependency graph make sense?
- [ ] `mise run docs-mikado migrate-immich-to-ringtail` shows the
chain correctly.
- [ ] Per-card implementation cycles land separately (commit
convention enforced by hook).

Bare image references in manifests were ambiguous — unclear whether the
tag was intentionally omitted or managed by kustomize. Add :kustomized
sentinel to all 37 image refs overridden by kustomize images transformer.
Add sync notes for tailscale-operator proxyclass (CRD fields not processed
by kustomize). Mark devpi reviewed (6.19.1 is current).

## Summary
- Move hardcoded image tags to kustomization.yaml `images:` transformer across **22 services** — image names in manifests become version-agnostic templates, with tags centralized in one place per service
- Replace hand-written ConfigMap manifests with `configMapGenerator:` in **12 services** — config data extracted to standalone files, generated ConfigMaps include content hashes that trigger automatic pod rollouts on changes
- Create new `kustomization.yaml` for **forgejo-runner** and **nvidia-device-plugin** (switches ArgoCD from directory mode to kustomize mode, rendered output identical)
### Services modified
**Images only (8):** cv, devpi, docs, kube-state-metrics, miniflux, navidrome, teslamate, torrent
**Images + configMapGenerator (10):** alloy-k8s, forgejo-runner, frigate, grafana, homepage, kiwix, loki, mosquitto, ntfy, prometheus
**Images only, no configMapGenerator (4):** authentik (skip blueprints — special YAML tags), tailscale-operator-base (Deployment only, CRD image fields left as-is)
**Skipped entirely (6):** argocd (remote upstream), databases (no image fields), external-secrets, grafana-config (cross-kustomization dashboards), immich (Helm-managed), 1password-connect/cloudnative-pg (no kustomization.yaml)
### What changes at deploy time
- **images:** — no functional diff, `kustomize build` produces identical output with tags
- **configMapGenerator:** — ConfigMap names gain hash suffixes (e.g., `prometheus-config` → `prometheus-config-6f42fhctcb`) and all Deployment/StatefulSet/DaemonSet references are updated automatically. Pods will restart once per service on first sync due to the name change
## Test plan
- [x] `kubectl kustomize` builds all 30 service directories successfully
- [x] Image tags verified in rendered output for all modified services
- [x] ConfigMap hash suffixes verified in rendered output
- [x] ConfigMap references in Deployments/StatefulSets confirmed to use hashed names
- [x] All pre-commit hooks pass (yamllint, shellcheck, prettier, etc.)
- [ ] `argocd app diff` each service to confirm only expected ConfigMap name changes
- [ ] Deploy from branch starting with a low-risk service (e.g., mosquitto)
