netbox: use canonical upstream image name for redis_exporter (#434)
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 netbox valkey metrics sidecar at `docker.io/oliver006/redis_exporter:v1.89.0`. Tag unchanged. `kustomize build --enable-helm apps/overlays/au-syd1/netbox` 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).

Export and scrape metrics from all redis/valkey instances (#398)
## 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).

Deploy NetBox (CNPG Postgres, Valkey, Authentik SSO) (#299)
## Why NetBox becomes the source of truth for host/interface/IPAM data as part of retiring Cobbler. The ENC role already moved to encapi; a kickstart-generation microservice that consumes NetBox comes later and is intentionally **out of scope** here. ## Change Adds the `netbox` app (namespace `netbox`, platform project) using the netbox-community helm chart via the OCI helm-through-kustomize pattern, plus estate-native data stores: - **NetBox** — chart `8.3.40` (appVersion `v4.6.5`), `oci://ghcr.io/netbox-community/netbox-chart`. 2 web replicas, 1 worker; bundled Postgres/Valkey subcharts disabled. Media on RWX CephFS so replicas share uploads. Chart `helm.sh/hook: test` Pod dropped via a kustomize delete patch (we deploy through ArgoCD, not `helm test`). - **CNPG Postgres** — `netbox-postgres`, 2 instances, PG 18, `cephrbd-fast-delete`. Standard per-cluster S3 backup: `barmanObjectStore -> s3://cnpg-netbox`, cephrgw `ObjectStoreUser` + `Bucket`, nightly `ScheduledBackup` at **03:40** (`0 40 3 * * *` — next free slot after grafana's 03:20), 30d retention. A pgbouncer `Pooler` (session mode) fronts it; NetBox connects via `netbox-postgres-pooler-rw`. - **Valkey** — standalone Deployment (`valkey/valkey:8-alpine`), AOF-persistent PVC on `cephrbd-fast-delete`. One instance: DB 0 = RQ task queue, DB 1 = cache. No auth (in-cluster, namespace-isolated). Chosen over the bundled Bitnami subchart to keep image control in-estate and avoid Bitnami's legacy-image churn; mirrors the litellm standalone-cache pattern. - **Ingress** — `Gateway` + `HTTPRoute` at `netbox.k8s.syd1.au.unkin.net` (`traefik-internal`, `vault-issuer` cert into `netbox-tls`, external-dns to the internal VIP), HTTP->HTTPS 301. - **Secrets** — all via VSO `VaultStaticSecret` (`postgres-credentials`, `netbox-secret-key`, `netbox-superuser`, `oauth-credentials`); no plain Secrets committed. The shared `default` k8s-auth role already binds `*` namespaces with a namespace-templated KV policy, so **no terraform-vault change is needed**. - **Authentik OIDC SSO** — `remoteAuth` wires `REMOTE_AUTH_ENABLED` + the `OpenIdConnectAuth` backend via chart values; `SOCIAL_AUTH_OIDC_*` via `extraConfig` (the chart's config loader globs `/run/config/extra/*/*.yaml`). The client secret is injected as a YAML fragment mounted from the Vault-synced `oauth-credentials` secret. New users auto-provision on first login. - Registers `netbox` in the platform ApplicationSet and AppProject (destination namespace + chart sourceRepo). ## Image table (source -> artifactapi -> DHI decision) All images flow through the estate's containerd registry mirrors; the allowlist patterns gate them. DHI (Docker Hardened Images) require authenticated pulls from a Docker Hub `dhi/` org and are **not** reachable through the anonymous mirror, so upstream official is used throughout. | Image | Upstream | Mirror / allowlist | Allowlisted? | DHI decision | |---|---|---|---|---| | NetBox app/worker/housekeeping | `ghcr.io/netbox-community/netbox:v4.6.5` | ghcr remote, `^netbox-community/` | **added in terraform-artifactapi #17** | No DHI published; upstream official | | CNPG Postgres | `ghcr.io/cloudnative-pg/postgresql:18.1-system-trixie` | ghcr, `^cloudnative-pg/` | already | estate-standard CNPG image | | Valkey | `docker.io/valkey/valkey:8-alpine` | dockerhub, `^valkey/valkey` | already | DHI not anon-pullable; upstream official | | NetBox init (perms) | `docker.io/busybox:1.38.0` | dockerhub, `^library/busybox` | already | upstream official | | Worker wait-for-backend | `docker.io/rancher/kubectl:v1.36.2` | dockerhub, `^rancher/` | already | upstream official | ## Cross-repo PRs (merge order) 1. **terraform-artifactapi #17** (`^netbox-community/` ghcr allowlist) — **merge before** this PR so the NetBox image pulls on first sync. 2. **terraform-authentik #11** (OIDC provider/application) — independent; SSO works once applied + the secret is seeded. 3. This PR. > Note: the CNPG S3-backup stanza pattern here is identical to PR #298 (already in main); it merges cleanly regardless of ordering. ## One-time Vault seeds (before/at first sync) ``` # App DB user (CNPG bootstrap + NetBox both consume this) vault kv put kv/kubernetes/namespace/netbox/default/postgres-credentials \ username=netbox password="$(openssl rand -base64 30)" # Django SECRET_KEY vault kv put kv/kubernetes/namespace/netbox/default/netbox-secret-key \ secret_key="$(python3 -c 'import secrets;print(secrets.token_urlsafe(60))')" # Bootstrap superuser vault kv put kv/kubernetes/namespace/netbox/default/netbox-superuser \ username=admin email=admin@unkin.net \ password="$(openssl rand -base64 24)" api_token="$(openssl rand -hex 20)" # OIDC client secret — ONE value stored two ways (raw for Authentik, YAML for NetBox) CS="$(openssl rand -base64 30)" vault kv put kv/kubernetes/namespace/netbox/default/oauth-credentials \ client_secret="$CS" oidc.yaml="SOCIAL_AUTH_OIDC_SECRET: \"$CS\"" ``` Seed `oauth-credentials` **before** applying terraform-authentik #11 (that apply reads `client_secret`). ## Validation - `kustomize build --enable-helm apps/overlays/au-syd1/netbox` — clean. - `kubeconform` (CI args, k8s 1.33.7): **27/27 valid, 0 invalid**. - `pre-commit` (yamllint + no-plain-secrets) on all changed files — pass. ## Out of scope The PXE/kickstart microservice that will consume NetBox — not scaffolded here. https://claude.ai/code/session_015ur3i7D2azsMAWTSVABApv Reviewed-on: #299 Co-authored-by: Ben Vincent <ben@unkin.net> Co-committed-by: Ben Vincent <ben@unkin.net> |
