Kubernetes in Practice is your one-stop shop for learning how to build, deploy, scale, and manage Kubernetes in a step-by-step process.

You will learn all the most important concepts including: architecture, pods, deployments, services, ingress, and a whole lot more. Once you have the fundamentals out of the way, you will get the opportunity to put your skills to work in a project where you will create and run an application in a real Kubernetes cluster.

By the time you finish this course, you will have complete confidence when it comes to deploying and managing kubernetes clusters.

# Running an Apache container

Creating a pod manifest file to run an Apache file is not much different than what we have seen before. 

apiVersion: v1
kind: Pod 
metadata:
    name: apache
spec:
    containers:
    - name: apache-container
      image: httpd

import React from 'react';
import { shallow, configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

configure({ adapter: new Adapter() });

import HelloWorld from './app';

var TestResult = function() {
    this.succeeded = false;
    this.reason = "";
    this.input = "";
    this.expected_output = "";
    this.actual_output = "";
}

export const executeTests = function() {

  var results = [];

  result = new TestResult();
  result.input = 'HelloWorld Component';
  result.expected_output = "span containing text 'Hello World'"

  let wrapper = shallow(<HelloWorld />);

  // Call your Challenge function here.

  let type = wrapper.type();
  let testSuccessful = true;
  let failureReason;

  if (type !== 'span') {
    testSuccessful = false;
    failureReason = "You need to render exactly one span HTML element";
  } else if (wrapper.props().children != "Hello World") {
     testSuccessful = false;
     failureReason = "You have rendered wrong message in your span element";
  }

  result.actual_output = wrapper.html();

  if (testSuccessful) {
    result.succeeded = true;
    result.reason = "Succeeded"
  } else {
    result.succeeded = false;
    result.reason = failureReason;
  }

  results.push(result);

  return results;
}

In the `apache.yaml` file, we're creating a pod named `apache`. We can name it whatever we want. But for this solution, we’re naming it “apache.” We can change the name of this pod in **line 4**. In **line 7 and 8**, we're specifying the name and image of the container. We're naming our container `apache`, and `httpd` is the name of the docker image that belongs to `Apache`.
