Database Manifests

PostgreSQL clusters managed by CloudNativePG operator.

Clusters

Cluster	Image	Purpose
blumeops-pg	cloudnative-pg/postgresql:18	General services (miniflux, teslamate)
immich-pg	tensorchord/cloudnative-vectorchord:17	Immich (requires pgvecto.rs extension)

blumeops-pg

Single-instance PostgreSQL cluster for blumeops services.

Configuration

• Instances: 1 (single-node for minikube)
• Storage: 10Gi on standard storage class
• Initial database: miniflux owned by miniflux user

Users/Roles

User	Role	Purpose	Password Source
postgres	superuser	CNPG internal (avoid using)	blumeops-pg-superuser secret
miniflux	app owner	Owns miniflux database	blumeops-pg-app secret
eblume	superuser	Admin access (matches brew pg)	blumeops-pg-eblume secret (manual)
borgmatic	pg_read_all_data	Backup access for borgmatic	blumeops-pg-borgmatic secret (manual)

Manual Secret Setup

Before deploying, create the password secrets:

# Create namespace first
kubectl create namespace databases

# Apply eblume password from 1Password
op inject -i argocd/manifests/databases/secret-eblume.yaml.tpl | kubectl apply -f -

# Apply borgmatic password from 1Password
op inject -i argocd/manifests/databases/secret-borgmatic.yaml.tpl | kubectl apply -f -

The miniflux user password is auto-generated by CloudNativePG and stored in blumeops-pg-app.

Connection Information

After the cluster is healthy:

# Connect via Tailscale (temporary hostname during migration)
psql -h k8s-pg.tail8d86e.ts.net -U eblume -W -d miniflux

# Or with password from 1Password
PGPASSWORD=$(op read "op://blumeops/guxu3j7ajhjyey6xxl2ovsl2ui/password") \
  psql -h k8s-pg.tail8d86e.ts.net -U eblume -d miniflux

# Get miniflux app credentials (for applications)
kubectl -n databases get secret blumeops-pg-app -o jsonpath='{.data.uri}' | base64 -d

# Get postgres superuser credentials (emergency only)
kubectl -n databases get secret blumeops-pg-superuser -o jsonpath='{.data.password}' | base64 -d

Connecting via kubectl port-forward

Alternative if Tailscale service is unavailable:

# Terminal 1: Port-forward to the primary
kubectl -n databases port-forward svc/blumeops-pg-rw 5432:5432

# Terminal 2: Connect as eblume
PGPASSWORD=$(op read "op://blumeops/guxu3j7ajhjyey6xxl2ovsl2ui/password") \
  psql -h localhost -U eblume -d miniflux

Status

# Check cluster health
kubectl -n databases get cluster blumeops-pg

# Check pods
kubectl -n databases get pods -l cnpg.io/cluster=blumeops-pg

# Check managed roles status
kubectl -n databases get cluster blumeops-pg -o jsonpath='{.status.managedRolesStatus}' | jq

# Operator logs
kubectl -n databases logs -l cnpg.io/cluster=blumeops-pg

Tailscale Exposure

Current: Temporary Service

k8s-pg.tail8d86e.ts.net - LoadBalancer service for testing during migration.

Phase 4: Production Service

After miniflux migrates to k8s, the pg.tail8d86e.ts.net Tailscale service will switch from brew PostgreSQL (indri) to this k8s cluster. At that point:

1. Delete service-tailscale.yaml (the k8s-pg service)
2. Update/create a service with tailscale.com/hostname: "pg"
3. Verify the orphaned k8s-pg device is removed from tailnet

immich-pg

PostgreSQL cluster for Immich with VectorChord extension for AI-powered vector search.

Configuration

• Instances: 1 (single-node for minikube)
• Storage: 10Gi on standard storage class
• Image: ghcr.io/tensorchord/cloudnative-vectorchord:17-0.5.0 (VectorChord 0.5.0 for Immich compatibility)
• Extensions: vector, vchord, cube, earthdistance

Connection

Immich connects via immich-pg-rw.databases.svc.cluster.local:5432.

The immich user password is auto-generated by CloudNativePG and stored in immich-pg-app secret:

# Get immich app credentials
kubectl -n databases get secret immich-pg-app -o jsonpath='{.data.password}' | base64 -d

Status

# Check cluster health
kubectl -n databases get cluster immich-pg

# Check pods
kubectl -n databases get pods -l cnpg.io/cluster=immich-pg
