Per user decision today: monitoring, mailserver, vault, descheduler,
metrics-server, traefik, technitium, crowdsec, redis, reverse-proxy,
reloader, headscale, wireguard, xray, cloudflared now participate in
the same `force + match-tag` regime as the rest of the cluster — Keel
watches the deployment's CURRENT tag for digest changes only and rolls
on push, never rewriting tag strings.
Two-part change:
stacks/kyverno/modules/kyverno/keel-annotations.tf
Trim the policy-level namespace exclude list from 31 → 16. The 16
remaining exclusions are the irreducible cluster-operator + state-
coupled set: keel itself, calico-system + tigera-operator (operator
loop), authentik (2026-05-17 pgbouncer incident bite), cnpg-system +
dbaas (state-coupled), kyverno, metallb-system, external-secrets,
proxmox-csi + nfs-csi + nvidia (just stabilized today, chart-pinned),
kube-system, vpa, sealed-secrets, infra-maintenance.
stacks/<each-of-15>/.../main.tf
Add `"keel.sh/enrolled" = "true"` label to the `kubernetes_namespace`
resource so the Kyverno mutate policy can target the workloads via
its namespaceSelector matchLabels.
Note on the apply path: the live ClusterPolicy was patched via
`kubectl patch` because the hashicorp/kubernetes provider v3.1.0 panics
during state refresh on Kyverno ClusterPolicy schemas with deeply
nested optional `context.celPreconditions` / `imageRegistry` fields
(see crash dump). The TF source above has the desired state, so any
clean future apply on a fixed provider version will be a no-op against
the live cluster.
Floating-tag workloads in the newly-enrolled set (will roll on every
upstream digest update — acceptable risk per user):
- wireguard: sclevine/wg:latest (image fixed today via iptables-nft
postStart shim)
- xray: teddysun/xray
- crowdsec-web: viktorbarzin/crowdsec_web
- monitoring: prompve/prometheus-pve-exporter:latest, prom/snmp-exporter
- traefik: nginx:1-alpine, openresty/openresty:alpine,
ghcr.io/tarampampam/error-pages:3
- redis: haproxy:3.1-alpine, redis:8-alpine
