In this lab, you will experience what it’s like to create and run a Kubernetes Operator that manages a custom resource. The Operator is created using the Operator SDK tool along with some Go code. This lab closely follows the Operator SDK documentation for building an Operator using Go .

The Operator pattern is an important technique to extend and build upon the basic features of Kubernetes. Operators are controllers with roles that observe and manage associated CustomResourceDefinitions (CRDs) . There are a variety of projects that provide tools to build Operators. The Operator SDK is one prominent technique.

In this lab, you will learn how to:

    ☐ Modify, build, and test code with an Operator SDK skeleton project
    ☐ Create a new CRD named Memcached using Go structs and automation
    ☐ Create a controller for observing and managing the Memcached custom resources
    ☐ Control the Memcached group using a declarative manifest and associated controller

It’s assumed that you are an application developer who is somewhat familiar with Kubernetes, containers, and Go.
