CNPG Recipe 27 - Running OpenBao on Kubernetes with a CloudNativePG PostgreSQL backend

A walkthrough of running OpenBao on Kubernetes with CloudNativePG as its PostgreSQL storage backend. Every layer of this stack is open source, with no vendor lock-in: Kubernetes and CloudNativePG are both CNCF projects, authenticated entirely over TLS client certificates via the 1.30 DatabaseRole CRD, with no passwords anywhere in the stack.
