Kubernetes is a powerful tool. It can help you manage complex applications and provide you with the ability to easily automate tasks involved in managing them. In this course, we will start exploring Kubernetes from a beginner's standpoint. We will discuss what Kubernetes is and what it does, and we will work with some of the basic functionality of Kubernetes hands-on. We will build a simple Kubernetes cluster. We will also deploy a sample microservice application to the cluster in order to explore how Kubernetes can help easily manage such applications.

A Practical Guide to Kubernetes

# The Sequence
Before we move onto Deployment updates, we'll go through our usual ritual 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 as those steps were already explained in the previous chapters.

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

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

3. The deployment controller creates a new ReplicaSet object.

In this lesson, we will go through the sequential breakdown of the Kubernetes Deployment process.
