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

## Creating a Pod

We'll create an `alpine`-based Pod that we'll use to demonstrate communication between Namespaces.

kubectl config use-context minikube

kubectl run test --image=alpine \
    --restart=Never sleep 10000

We switched to the `minikube` context (`default` Namespace) and created a Pod with a container based on the `alpine` image. We let it `sleep` for a long time. Otherwise, the container would be without a process and would stop almost immediately.

Before we proceed, we should confirm that the Pod is indeed running.

NAME READY STATUS  RESTARTS AGE
test 1/1   Running 0        10m

Please wait a few moments if, in your case, the Pod is not yet ready.
## Establishing the Communication
Before we proceed, we'll install `curl` inside the container in the `test` Pod.
