The custom startup command was causing CouchDB to crash during initialization.
The official couchdb:3.3 image has a proper entrypoint that handles all setup
correctly using environment variables.
Changes:
- Removed custom command/entrypoint override
- Rely on official CouchDB image's built-in initialization
- Increased probe delays and failure thresholds for stability
- Liveness: initialDelay 60s, failureThreshold 6
- Readiness: initialDelay 30s, failureThreshold 6
- Removed NODENAME, ERL_FLAGS, and COUCHDB_SINGLE_NODE_ENABLED env vars
(handled by image defaults)
Result:
- CouchDB starts cleanly without crashes
- Backend connects successfully
- Health endpoint confirms: couchdb: connected
Deployment status: All pods running (3/3)

Headless services (clusterIP: None) don't get DNS entries for the service name itself,
only for individual pods. This was causing DNS resolution failures for the backend
trying to connect to adopt-a-street-couchdb.
Since we only have 1 replica, a regular ClusterIP service works better and provides
proper DNS resolution.
Fixes:
- Backend can now resolve adopt-a-street-couchdb DNS name
- CouchDB connection is stable
- Health endpoint returns connected status
Deployment status:
- Backend: 1/1 Ready, healthy, connected to CouchDB
- Frontend: 1/1 Ready, serving nginx
- CouchDB: 1/1 Ready, StatefulSet with 10Gi storage
- Ingress: Routing working at 192.168.153.241

- Remove namespace: adopt-a-street from all metadata sections
- Update CouchDB NODENAME to use namespace-agnostic format
- Make all manifests deployable to any namespace
- Maintain service names and selectors for functionality
- All manifests validated with kubectl dry-run
Now manifests can be deployed to any namespace using:
kubectl apply -n <namespace> -f deploy/k8s/

- Migrate Report model to CouchDB with embedded street/user data
- Migrate UserBadge model to CouchDB with badge population
- Update all remaining routes (reports, users, badges, payments) to use CouchDB
- Add CouchDB health check and graceful shutdown to server.js
- Add missing methods to couchdbService (checkConnection, findWithPagination, etc.)
