- Prometheus: change nodeSelector from hardware=high-memory (nonexistent label) to kubernetes.io/arch: amd64
Fixes OOMKilled cause - pod was being scheduled on wrong nodes.
- litellm-deployment: add resource limits (2Gi/500m requests, 4Gi/2000m limits) + pin image to v1.34.0
Fixes OOMKilled cause - no resource limits were set.
- gitea-runner: pin image to v0.12.0 from :latest + add resource limits (512Mi/250m requests, 1Gi/500m limits)
Addresses extreme restart count (281) caused by unbounded memory usage and rolling image updates.
Survey of dashboards that could be built from existing and not-yet-enabled
metrics across the cluster's services (traefik, coredns, metallb, cert-manager,
phoenix, litellm, gitea, postgres, etc.), with per-service enable steps and
a recommended priority order.
