The Journey of a Microservice: From Source Code to a Full-Blown Kubernetes Deployment

In this lecture, we’ll containerize and deploy a RESTful Go microservice to a Kubernetes cluster. We’ll also learn about some important building blocks of our cluster such as Deployments, Services, ConfigMaps, Secrets, Ingresses, and the like.
