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 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
