CloudNativePG: PostgreSQL on Kubernetes

by Shriira Press

A practical, in-depth guide to CloudNativePG, the open-source Kubernetes operator for PostgreSQL. Learn how CloudNativePG runs production databases on Kubernetes: the database-on-Kubernetes problem (why stateful databases are hard), the operator model and the Cluster resource, the architecture (primary, replicas, streaming replication), high availability and automatic failover (avoiding split-brain and data loss), storage/backup/point-in-time recovery, replication/scaling/connection pooling with PgBouncer, day-2 operations (rolling updates, config, monitoring, scaling), security and best practices (TLS, RBAC, defense in depth), and CloudNativePG in practice.
