Container images

Managing extensions is one of the biggest challenges in running PostgreSQL on Kubernetes. In this article, I explain why I believe CloudNativePG —now a CNCF Sandbox project—is on the verge of a breakthrough. Two important new features for both PostgreSQL and Kubernetes—the extension_control_path option and image volumes—will guarantee immutability to extension container images.

In this article, I’ll explore how Kubernetes and CloudNativePG can be leveraged to streamline the testing of PostgreSQL patches, especially during a Commitfest. By automating the creation of PostgreSQL container images from any public Git repository, developers and reviewers can quickly and efficiently test patches within a Kubernetes environment. This approach not only saves time but also enhances the reliability of patches before integration into the main codebase.
