CloudNative PG

CloudNativePG is the Kubernetes operator that runs PostgreSQL on your own cluster. Edka installs it when you provision a PostgreSQL runtime through the Databases workspace and manages the cluster lifecycle through its CRDs.

• Runs 1, 3, or 5 instances with synchronous replication and automated failover
• Continuous backups to S3 compatible storage or Google Cloud Storage, with point in time recovery
• Restore to a new database from point in time recovery or a completed backup
• Connection pooling with a PgBouncer pooler
• Declarative roles, databases, extensions, pg_hba, pg_ident, and custom PostgreSQL parameters
• A data volume plus an optional dedicated pg_wal volume
• Runtime metrics: connection usage, throughput, cache hit ratio, and replica lag

How it fits in Edka

Edka installs cloudnative-pg as a PostgreSQL dependency alongside cert-manager, and adds barman-cloud-cnpg-plugin when backups are enabled. The catalog currently runs PostgreSQL 18.3, 18.1, 17.9, 16.13, and 15.17.
