We're excited to announce the release of PGO 5.0, the open source Postgres Operator from Crunchy Data . While I'm very excited for you to try out PGO 5.0 and provide feedback, I also want to provide some background on this release. When I joined Crunchy Data back in 2018, I had heard of Kubernetes through my various open source activities, but I did not know much about it. I learned that we had been running Postgres on Kubernetes and OpenShift in production environments for years. T...

We're excited to announce the new version of PGO , the open source Postgres Operator from Crunchy Data version 4.7! There's a lot of really cool features that make it easy to deploy production Postgres clusters on Kubernetes. In this release, we focused on adding enhancements around "Day 2" operations (e.g. PVC resizing), allowing for backups to be stored in Google Cloud Storage ( GCS ), improvements to monitoring, and included more Postgres extensions ! Let's take a quick tour of all of...

Not too long ago I wrote a blog post about how to deploy TLS for Postgres on Kubernetes in attempt to provide a helpful guide from bringing your own TLS/PKI setup to Postgres clusters on Kubernetes. In part, I also wanted a personal reference for how to do it! However, some things have changed since I first wrote that post. OpenSSL released a fix for CVE-2021-3450 (courtesy to my colleague Tom Swartz for reminding me of this) that prevents users from bypassing some of the x509 certificate...

Whether you are starting a new development project, launching an application modernization effort, or engaging in digital transformation, chances are you are evaluating Kubernetes. If you selected Kubernetes, chances are you will ultimately need a database . Kubernetes provides many benefits for running applications including efficiency, automation, or infrastructure abstraction. These features allow you to deploy highly availability databases and scale, making it easier to manage hardware f...

Please Note: This post references an older version of the Crunchy Postgres for Kubernetes. See PGO Documentation for the latest version. The Crunchy Data team announced the latest release of our open source PostgreSQL Operator for Kubernetes 4.6 a few weeks back. So let's take a whirlwind tour of how we make it easy to run production-quality Postgres on Kubernetes. With this release, we included features to streamline management of the Operator, added security features, and extra system metric...

This post provides guidance for v4x. For the latest on PGO, GitOps and Helm installer, please see: https://github.com/CrunchyData/postgres-operator-examples/tree/main/helm In the previous article , we explored GitOps and how to apply GitOps concepts to PostgreSQL in a Kubernetes environment with the Postgres Operator and custom resources. The article went on to mention additional tooling that has been created to help employ GitOps principles within an environment, including Helm . While the m...

Recently I ran across grand sweeping statements that suggest containers are not ready for prime time as a vehicle for deploying your databases. The definition of "futile" is something like "serving no useful purpose; completely ineffective". See why I say this below, but in short, you probably are already, for all intents and purposes, running your database in a "container". Therefore, your resistance is futile. And I'm here to tell you that, at least in so far as PostgreSQL is concerned, those...

The desire to use Pod tolerations to schedule Postgres instances sometimes comes up around complex Kubernetes deployments. To address this feedback, we added support for tolerations to the 4.6 release of the Postgres Operator along with improvements to using node affinity . To use tolerations with PostgreSQL deployments, it helps to understand some of the mechanics behind several Kubernetes features to get the desired result of deploying PostgreSQL to a specific node group. Let's take a loo...

" GitOps " is a term that I've been seeing come up more and more. The concept was first put forward by the team at Weaveworks as a way to consolidate thought around deploying applications. In essence: your deployment topology lives in your git repository. You can update your deployment information by adding a new commit. Likewise, if you need to revert your system's state, you can rollback to the commit that you want to represent your production environment. Any changes to your deployment topo...

TLS allows for the secure transmission of data between systems and is also a requirement of many production environments . Part of setting up TLS is ensuring anything communicating over a network within your system also has TLS. If you are not encrypting traffic between all your endpoints, you open yourself up to snooping. An earlier post describes how to set up PostgreSQL clusters with TLS on Kubernetes using the Crunchy Data PostgreSQL Operator . This setup works well for creating encrypte...
