Technical requirements

This chapter will continue to work with the nginx Operator that was written in Chapter 4, Developing an Operator with the Operator SDK, and Chapter 5, Developing an Operator – Advanced Functionality.

• Access to a Kubernetes cluster. It is recommended to use a disposable cluster created with a tool such as kind or minikube (see Chapter 6, Building and Deploying Your Operator).
• The kubectl binary available on your local system for interacting with the Kubernetes cluster.
• The operator-sdk binary available on your local system for deploying the OLM and building Operator manifests.
• Docker installed and running to build Operator bundle...
