The mysql-data-pvc was already dynamically provisioned by the cluster's
'local-path' StorageClass. The overlay patch tried to change storageClassName
to 'manual' and volumeName on an already-bound PVC, which Kubernetes forbids:
"spec is immutable after creation except resources.requests"
Fixes:
- Remove mysql-pvc-patch from kustomization.yaml (PVC left as-is)
- Remove mysql-pv.yaml resource (not needed with dynamic provisioner)
- Add comment explaining when manual PV/PVC is needed vs not
Jenkinsfile: add --timeout and FQDN to smoke test curl; add comments
explaining MySQL Recreate strategy startup timing expectations.

Database fixes:
- Add hostPath.type=DirectoryOrCreate so kubelet auto-creates /mnt/data/mysql
- Add fsGroup=999 so MySQL process can write to the hostPath volume
- Add MYSQL_ROOT_HOST=% to allow backend pods to authenticate as root
- Fix liveness/readiness probes to include credentials (-p$MYSQL_ROOT_PASSWORD)
- Increase probe initialDelaySeconds (30/60s) for slow first-run init
- Add 15s grace sleep in backend initContainer after MySQL TCP is up
- Add persistentVolumeReclaimPolicy=Retain to prevent accidental data loss
- Explicit accessModes+resources in PVC patch to avoid list merge ambiguity
- Add nodeAffinity comment in PV for multi-node cluster guidance
Ingress/nginx fixes:
- Remove broken rewrite-target=/ that was rewriting all paths (incl /api) to /
- Route /socket.io directly to backend for WebSocket support
- Add /socket.io/ proxy location to both nginx.conf and K8s ConfigMap
Frontend fix:
- Persist currentUser to localStorage on login so page refresh no longer
clears session and redirects users back to the login page
Tooling:
- Add k8s/overlays/on-premise/deploy.sh for one-command deployment
