CloudNativePG is a Kubernetes Operator that simplifies hosting and managing highly available PostgreSQL clusters in Kubernetes. Running a stateful service like PostgreSQL on Kubernetes can be complex, requiring deep knowledge of both Kubernetes and PostgreSQL replication. CloudNativePG abstracts much of this complexity by treating the entire PostgreSQL cluster as a single, configurable declarative resource. It provides seamless primary/standby architecture using native streaming replication and includes high-availability features out of the box, including self-healing capabilities, automated failover that promotes the most aligned replica and automatic recreation of failed replicas. If you're looking to host PostgreSQL on Kubernetes, CloudNativePG is a solid place to start.
