From 13a04a6ebc084f1c00d14d3e6809abb9391246c3 Mon Sep 17 00:00:00 2001 From: unkin-agent Date: Sun, 23 Aug 2026 19:19:16 +1000 Subject: [PATCH] Export and scrape metrics from all redis/valkey instances (#398) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 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).
