Jump right into Kubernetes development with career-focused lessons and hands-on practice.

DevOps for Developers

Kubernetes is a powerful container management tool that's taking the world by storm. This detailed course will help you master it.

In this course, you'll start with the fundamentals of Kubernetes and what the main components of a cluster look like. You'll then learn how to use those components to build, test, deploy, and upgrade applications, as well as how to achieve state persistence once your application is deployed. You'll also learn how to secure your deployments and manage resources, which are crucial DevOps skills.

By the time you're done, you'll have a firm grasp on what Kubernetes is, as well as the skills to deploy your own clusters and applications with confidence.

A Practical Guide to Kubernetes

# The sequence
Before we move onto Deployment updates, we’ll go through our usual step of seeing the process through a sequence diagram. We won’t repeat the explanation of the events that happened after the ReplicaSet object was created because those steps have already been explained in the previous chapters.

1. The Kubernetes client (`kubectl`) sends a request to the API server requesting the creation of a Deployment defined in the `go-demo-2-db.yml` file.

2. The Deployment controller is watching the API server for new events, and it detects that there is a new Deployment object.

3. The Deployment controller creates a new ReplicaSet object.
