rke2's `registries.yaml` already rewrites upstream image names to the artifactapi mirror, so manifests must carry canonical upstream names. Only in-house `artifactapi.k8s.syd1.au.unkin.net/docker-internal/...` images stay explicit.
Changes:
- Point the gitea valkey metrics sidecar at `docker.io/oliver006/redis_exporter:v1.89.0`.
Tag unchanged. `kustomize build --enable-helm apps/overlays/au-syd1/gitea` differs from main only in that image string. No extra proxied refs in the file (the `valkey/valkey:8-alpine` container is already a bare upstream name).

## Why
No redis/valkey instance managed in this repo exports metrics today — the six caches (artifactapi, authentik, litellm, gitea, netbox, jellyfin) are blind spots in VictoriaMetrics.
## What
- Enables the valkey-operator exporter sidecar on the jellyfin ValkeyCluster (`exporter.enabled: true`); overrides the operator's default bare-dockerhub image (`oliver006/redis_exporter:v1.80.0`) with the artifactapi-proxied pin. The operator manages a dedicated `_exporter` ACL user for it.
- Adds a `metrics-exporter` sidecar (`artifactapi.k8s.syd1.au.unkin.net/dockerhub/oliver006/redis_exporter:v1.89.0`, :9121, port name `metrics`, req 32Mi/25m lim 64Mi/100m) to the five raw Deployments: artifactapi/authentik/litellm redis and gitea/netbox valkey. gitea/netbox sidecars get the same restrictive securityContext as their valkey container.
- Adds the `monitoring.unkin.net/redis-exporter: "true"` opt-in pod label to all five pod templates.
- Adds `apps/base/observability/vmpodscrape-redis.yaml` with two VMPodScrapes (any namespace, port `metrics`): `redis-exporters` selecting the opt-in label, and `valkey-operator-clusters` selecting `app.kubernetes.io/managed-by: valkey-operator` + `app.kubernetes.io/component: valkey-node` — the ValkeyCluster CR has no pod-label passthrough (verified against the v0.5.0 CRD/source), so operator pods cannot carry the opt-in label.
## Notes
- No instance runs with `requirepass`/auth, so no REDIS_PASSWORD wiring is needed on the raw Deployments; the jellyfin exporter auth is operator-managed.
- Validated: `kustomize build` on every touched base + au-syd1 overlay (helm overlays with `--enable-helm`) and `kubeconform -strict -ignore-missing-schemas` (68 valid, 0 invalid).

Stand up the git.unkin.net forge on k8s to replace the Puppet VM. Deployed HA-shaped to match what the VM already runs (multi-replica on shared storage + external DB/cache), so this is genuine multi-replica HA rather than single-replica failover. Serves a temporary git2.k8s.syd1.au.unkin.net host; the git.unkin.net cutover is staged in docs/gitea-migration.md.
- add apps/base/gitea: namespace, CNPG gitea-postgres (2 instances, S3 backup bucket cnpg-gitea, nightly 04:00/30d), pgbouncer pooler, standalone Valkey (session/cache/queue, AOF), VaultAuth + VaultStaticSecrets, Gateway + HTTPRoute
- add apps/overlays/au-syd1/gitea: official Gitea chart 12.6.0 (app 1.26.2, rootless, 2 replicas) via helm-through-kustomize; RWX CephFS repo storage, external CNPG + Valkey, Actions disabled, container registry disabled (moved to artifactapi), Authentik OIDC with auto-register/account-linking; SSH via LoadBalancer VIP 198.18.200.10:2222
- register gitea in the platform ApplicationSet + AppProject
- add docs/gitea-migration.md staged cutover plan (VM Postgres->CNPG dump/restore, DNS in main.unkin.net zone, consumer checklist, rollback)
Depends on: terraform-authentik gitea OIDC app, and terraform-artifactapi ^gitea/ dockerhub allowlist (both separate PRs). One-time Vault seeds are listed in the migration doc.
