CNPG Recipe 26 - Extension image catalogs

Thu, 06 Aug 2026 22:08:58 +1000

CloudNativePG lets the ClusterImageCatalog carry extension images alongside the operand, a capability every currently supported release already has, so a Cluster manifest only needs to name an extension and nothing else. This recipe deploys the community’s extension catalog and shows the operator resolving pgvector’s image, paths and dependencies from a single, versioned source of truth per PostgreSQL major version. More importantly, it is the piece of infrastructure that turns extension distribution into a real ecosystem: once an extension lands in the catalog, every Cluster that references it inherits it for free, with no manifest ever needing to change again.
