Alauda Container Platform

About Alauda Data Services Relational Database E3

Alauda Data Services Relational Database E3 packages the upstream CloudNativePG (CNCF Sandbox) operator for Alauda Container Platform. Unlike older PostgreSQL operators that wrap Patroni and depend on a separate distributed consensus store (etcd, ZooKeeper), CNPG implements primary/standby coordination directly using Kubernetes primitives, significantly reducing failover time and removing an external dependency. PostgreSQL versions 14 through 18 are supported, with standard and minimal container variants for both amd64 and arm64.

The Alauda distribution adds air-gapped operation (mirror-registry images for the operator, PostgreSQL containers, extensions, and PgBouncer), image-rewrite tolerance for ACP's admission rewriting, ACP-aligned L5 RBAC, and packaging via violet push to the platform OLM catalog source.
