## Why The k8s au-syd1 VictoriaMetrics stack ran as two helm charts and only scraped in-cluster targets. The victoria-metrics-operator already runs in vm-system, so this moves the stack onto operator-managed CRDs. That unlocks VMServiceScrape/VMPodScrape (auto-converted from Prometheus ServiceMonitors, used by a follow-up PR) and adds Consul service discovery so the cluster scrapes the **same puppet-prod targets** as the puppet vmagent. Also shrinks vmstorage 3 → 2 (Ceph-backed, replicationFactor 2). ## Changes - Add **VMCluster `main`**: vmstorage 2 replicas (cephrbd-fast-delete 200Gi, 180d retention, replicationFactor 2), vminsert/vmselect 2 replicas + HPA (2–10, 60% cpu). - Add **VMAgent `main`**: retains the kubernetes SD jobs (apiservers/nodes/cadvisor), `selectAllByDefault` for VMServiceScrape/VMPodScrape, and a **Consul SD job** against `consul.service.consul` (resolves to the puppet Consul from pods) replicating the puppet vmagent relabels — keep tag `metrics`, `__scheme__` from `metrics_scheme`, `job` from `metrics_job`. TLS is **verified against the reflected `vault-ca-cert`** (no insecure skip-verify). - Expose vmselect/vminsert/vmagent via **Gateway API** (traefik-internal Gateway + HTTPRoute, http→https redirect), same hostnames. - Remove the two helm charts, their values files, and vendored charts. ## Notes - Data wipe on cutover is acceptable (confirmed) — old helm PVCs can be deleted. - Verify at rollout: pods resolve `*.main.unkin.net` node FQDNs (needed for CA SAN match on scrape targets); `/targets` shows `job=consul`.
