## Summary
C2 Mikado chain for deploying Authentik as the SSO identity provider, replacing Dex.
This PR will evolve over multiple sessions. Each iteration adds documentation (prerequisite cards) and eventually code as leaf nodes are resolved.
## Current Mikado State
- **Goal:** `deploy-authentik` (active)
- **Leaf prerequisites:**
- `build-authentik-container` — Build Nix container image
- `provision-authentik-database` — Create PostgreSQL database on CNPG cluster
- `create-authentik-secrets` — Create 1Password item with credentials
## Process refinements
- Updated agent-change-process with lessons from first attempt: reset code before committing cards, open PRs early
## Test plan
- [ ] `mise run docs-mikado` shows correct dependency chain
- [ ] Leaf nodes can be worked independently
- [ ] Container builds on ringtail
- [ ] Authentik starts and reaches healthy state
- [ ] Forgejo OAuth2 connector works

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
