Added `tier = var.tier` to kubernetes_namespace labels in ~73 service
modules. This enables Kyverno to generate LimitRange defaults,
ResourceQuotas, and PriorityClass injection for all namespaces.
Previously only 11 namespaces had tier labels; now all 80 active
namespaces are labeled. All pods restarted in rolling waves to pick
up the new policies.
Add MySQL datasource and 15-panel dashboard for DNS analytics:
queries over time, response codes, top domains/clients, response
times, blocked/NxDomain domains. Enable Grafana dashboard sidecar
for auto-provisioning dashboards from ConfigMaps.
Single template regex in the viktorbarzin.lan block catches ALL search
domain expansion junk (*.com.viktorbarzin.lan, *.cluster.local.viktorbarzin.lan,
etc.) instead of needing separate server blocks per pattern. Legitimate
single-label queries (idrac.viktorbarzin.lan) fall through to Technitium.
DNS queries were going through Traefik's IngressRouteUDP, replacing
real client IPs with Traefik pod IPs (10.10.169.150) in Technitium logs.
Changed Technitium DNS service from NodePort to LoadBalancer with
externalTrafficPolicy: Local, removed dns-udp entrypoint and
IngressRouteUDP from Traefik, and updated CoreDNS to forward .lan
queries to Technitium's LoadBalancer IP directly.
Add kubernetes_config_map for CoreDNS to the technitium module, with a
template block for cluster.local.viktorbarzin.lan that returns NXDOMAIN
immediately. This prevents ndots:5 search domain expansion from flooding
Technitium with ~66k/day junk queries (e.g.
redis.redis.svc.cluster.local.viktorbarzin.lan).
Also enabled saveCache on Technitium so the DNS cache persists across
pod restarts.
