Graph Studio Deployment with Data Persistence

Overview & Use Case

This configuration is used to deploy Graph Studio with persistent storage using Kubernetes Persistent Volume Claims (PVCs). It is intended for production or stateful deployments where Graph Studio server data, logs, activation state, and working caches must persist across pod restarts, upgrades, or node reschedules.

Key Highlights

• Persistent Volume Claims: Provisions a volume claim (persistence-volume) with 10Gi storage and Retain reclaim policy.
• Volume Mounts: Mounts subpaths for activation state (/k8s-startup-data/activation), server data (/opt/anzo/Server/data), and logs (/opt/anzo/Server/logs).
• Init Container: Uses an anzo-init container to prepare directory subpaths prior to Graph Studio startup.
• Working Cache: Configures an emptyDir volume for temporary working cache (/opt/anzo/Server/data/anzowtcache).
