Unleashing the Power of Postgres in Kubernetes

A first look at what CloudNativePG 1.31 will bring to PostgreSQL credentials: a DatabaseRole can now generate its own password, keep it in a Secret the operator owns, shape it with criteria and rotate it on a schedule, with PostgreSQL enforcing the lifeti…

This recipe shows how to perform an online major PostgreSQL upgrade using the new declarative approach to logical replication introduced in CloudNativePG 1.25.

In this CNPG recipe, we explore three essential command-line tools that simplify working with CloudNativePG in Kubernetes: view-secret, view-cert, and stern.

Welcome CNPG Playground, a local learning environment for exploring CloudNativePG and PostgreSQL in Kubernetes.

CloudNativePG 1.24 introduces a highly customisable approach to managing PostgreSQL synchronous replication through the new .spec.postgresql.synchronous stanza.

In this article, I’ll explore how Kubernetes and CloudNativePG can be leveraged to streamline the testing of PostgreSQL patches, especially during a Commitfest.

In this article, I’ll introduce you to the service template feature in CloudNativePG, which greatly simplifies the creation of services such as LoadBalancer to expose PostgreSQL outside of your Kubernetes cluster - particularly useful for streamlining Dat…

In modern Kubernetes environments, isolating PostgreSQL workloads is crucial for ensuring stability, security, and performance.

This article provides a step-by-step guide to deploying PostgreSQL in Kubernetes using the kind tool (Kubernetes IN Docker) on a local machine, simulating a production-like environment.

As Kubernetes celebrates its tenth anniversary, the integration of PostgreSQL within this ecosystem is gaining momentum, offering challenges and opportunities, rather than threats, for database administrators (DBAs).

Join me and PostgreSQL/Kubernetes expert Leonardo Cecchi in Athens on October 22 for the first-ever public training session on CloudNativePG at the 2024 PostgreSQL European Conference, where you’ll master essential day-2 operations for PostgreSQL in Kuber…

In this blog post, I delve into the crucial aspects of networking and storage within a CloudNativePG cluster deployed on Kubernetes.

The upcoming CloudNativePG 1.24 introduces a game-changing feature: the ability to declaratively manage PostgreSQL cluster switchover across cloud regions or different Kubernetes clusters.

As Kubernetes marks its tenth anniversary, its influence on infrastructure management continues to grow.
