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

# Opening Jenkins in a Browser
Now that everything is up and running, we can open Jenkins UI in a browser.

## 📝  A note to Windows users

> Git Bash might not be able to use the `open` command. If that's the case, please replace the `open` command with `echo`. As a result, you'll get the full address that should be opened directly in your browser of choice.
# Creating a Job
Please click the *Log in* link, type *jdoe* as the *User*, and *incognito* as the *Password*. When finished, click the *log in* button.

Now that we are authenticated as `jdoe` administrator, we can proceed and create a job. That will generate a state that we can use to explore what happens when a stateful application fails.

Please click the *create new jobs* link, type *my-job* as the item name, select *Pipeline* as the job type, and press the *OK* button.

You'll be presented with the job configuration screen. There's no need to do anything here since we are not, at the moment, interested in any specific Pipeline definition. It's enough to click the *Save* button.

# Simulating and Analyzing Failure
Next, we'll simulate a failure by killing `java` process running inside the Pod created by the `jenkins` Deployment. To do that, we need to find out the name of the Pod.

In this lesson, we will analyze the failure of Jenkins application due to lack of handling the state persistence.
