Introduction

Note

This guide is intended for readers that are familiar with using Kubernetes and understand the purpose of an operator. Additional deployment methods are available in the Deploy SingleStore guide.

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.

Verification instructions

Note: You must install cosign to verify the authenticity of the SingleStore file.

Use the following steps to verify the authenticity of singlestoredb-server, singlestoredb-toolbox, singlestoredb-studio, and singlestore-client SingleStore files that have been downloaded.

You may perform the following steps on any computer that can run cosign, such as the main deployment host of the cluster.

  1. (Optional) Run the following command to view the associated signature files.

    curl undefined
  2. Download the signature file from the SingleStore release server.

    • Option 1: Click the Download Signature button next to the SingleStore file.

    • Option 2: Copy and paste the following URL into the address bar of your browser and save the signature file.

    • Option 3: Run the following command to download the signature file.

      curl -O undefined
  3. After the signature file has been downloaded, run the following command to verify the authenticity of the SingleStore file.

    echo -n undefined |
    cosign verify-blob --certificate-oidc-issuer https://oidc.eks.us-east-1.amazonaws.com/id/CCDCDBA1379A5596AB5B2E46DCA385BC \
    --certificate-identity https://kubernetes.io/namespaces/freya-production/serviceaccounts/job-worker \
    --bundle undefined \
