Kubernetes

Introduction

In this tutorial, you will deploy a cluster in a Kubernetes environment using a Kubernetes operator. This operator allows you to easily resize clusters, replace failing nodes, and upgrade to newer versions of SingleStore seamlessly. And like other Kubernetes operators, you can use it to deploy clusters easily in many different environments and platforms using Red Hat OpenShift.

The SingleStore (formerly MemSQL) Operator (or simply, "the Operator") is also certified to run on the various Red Hat OpenShift platforms, so it will work natively with the OpenShift UI portal and other OpenShift management tools. It can also be downloaded directly from Docker Hub when referenced in the Operator deployment file. The official Docker Hub page for SingleStore is hub.docker.com/u/singlestore.

A four-node cluster is the minimal recommended cluster size for showcasing SingleStore as a distributed, highly-available database; however, you can use the procedures in this tutorial to scale out to additional nodes for increased performance over large data sets or to handle higher concurrency loads. Refer to Distributed Architecture to learn more about SingleStore’s distributed architecture, design principles, and topology concepts.
