The Crunchy PostgreSQL Operator 4.0 provides an open source PostgreSQL-as-a-Service for Kubernetes platform.
Crunchy Data recently released version 2.6 of the PostgreSQL Kubernetes Operator, a powerful controller that follows the Kubernetes Operator pattern that enables users to provision and manage thousands of PostgreSQL databases at scale. We thought that we would demonstrate some of the features in this latest version over the next few weeks, which includes support for manual database failover, storage selection, node (or server) selection preference, and many goodies that make it easier to manage a large PostgreSQL cluster.
One of the biggest benefits of running PostgreSQL is running your cluster in primary-replica setup for the purposes of high-availability or load balancing your read-only queries. It is not necessarily simple to deploy a primary-replica setup out of the box, but by using modern containerization technology, we can greatly simplify the process.
The open source software ecosystem around PostgreSQL is as robust as the database itself, but sometimes it can be hard for people new to PostgreSQL, and even some seasoned veterans, to get all of the software dependencies for their development environment setup on their computers.
At Crunchy Data, we obsess on making things as easy as possible for people to get software up and running, regardless of the technology. While I was trying to find things to experiment with using Docker, one of our engineers gave me a recipe to setup PostgreSQL 10 and pgAdmin 4 easily and quickly. It was so simple, I thought it would be fun to share it!
