Note: the name of this branch was chosen before the scope widened to encompass the entire observability stack. Summary - Fix Grafana data source URLs (docker driver uses host.minikube.internal, not host.containers.internal) - Migrate Prometheus and Loki from indri to Kubernetes with Tailscale Ingresses - Expose CNPG PostgreSQL metrics via Tailscale and update dashboard to use cnpg_* metrics - Update Alloy to push metrics/logs to k8s endpoints (prometheus.tail8d86e.ts.net, loki.tail8d86e.ts.net) - Add ACL rule for port 9187 (CNPG metrics) - Delete obsolete ansible roles for prometheus and loki Changes - argocd/manifests/prometheus/ - New Prometheus StatefulSet with 20Gi PVC and Tailscale Ingress - argocd/manifests/loki/ - New Loki StatefulSet with 20Gi PVC and Tailscale Ingress - argocd/apps/prometheus.yaml, argocd/apps/loki.yaml - ArgoCD Applications - argocd/manifests/grafana/values.yaml - Data sources now use k8s internal DNS - argocd/manifests/databases/service-metrics-tailscale.yaml - CNPG metrics endpoint - argocd/manifests/grafana-config/dashboards/configmap-postgresql.yaml - Updated to cnpg_* metrics - ansible/roles/alloy/defaults/main.yml - Push to k8s Tailscale endpoints - pulumi/policy.hujson - ACL for port 9187 - Deleted ansible/roles/prometheus/ and ansible/roles/loki/ Deployment and Testing - Stop prometheus and loki on indri - Sync ArgoCD apps (apps, prometheus, loki, grafana) - Run mise run provision-indri -- --tags alloy - Verify Grafana dashboards show data 🤖 Generated with https://claude.ai/claude-code Reviewed-on: https://forge.tail8d86e.ts.net/eblume/blumeops/pulls/42
