Cloud DevOps Engineer Capstone Project

Overview

In this project I applied the skills and knowledge which were developed throughout the Cloud DevOps Nanodegree program. These included:

Working in AWS
Using Jenkins to implement Continuous Integration and Continuous Deployment
Building pipelines
Working with Ansible and CloudFormation to deploy clusters
Building Kubernetes clusters
Building Docker containers in pipelines

Propose and Scope the Project

For the Docker application I used an Nginx “Hello World, my name is Luka.” application.
As a deployment type, I applied a blue/green deployment.
I used Jenkins to manage Continuous Integration phases.

Project walkthrough Steps

Create on EC2 an Ubuntu Server (Screenshot 1 till Screenshot 9)

I used an Ubuntu v20, and referenced this tutorial for Jenkins installation: https://www.journaldev.com/33965/install-jenkins-on-ubuntu

Step1: Install Prerequisites

sudo apt update sudo apt install openjdk-8-jdk

Step 2: Retrieve and add the GPG Public Keys

wget https://pkg.jenkins.io/debian/jenkins.io.key sudo apt-key add jenkins.io.key

Step 3: Add the Jenkins Repository to the Sources List

Insert "deb https://pkg.jenkins.io/debian-stable binary/" in /etc/apt/sources.list

Step 4: Install Jenkins on Ubuntu

sudo apt update sudo apt install jenkins

Step 5: Verify Jenkins Installation

sudo systemctl status jenkins

Step 6: Allow incoming connections into Jenkins and install tidy

sudo ufw allow 8080 sudo apt install tidy

Created Jenkins pipeline

I created a Jenkinse pipeline. The result of the pipeline: Screenshot 11 - Jenkis pipeline I pushed the created docker image on Docker Hub: Screenshot 10 - DockerHub Repository

Code is checked against a linter as part of a Continuous Integration step (demonstrated w/ two screenshots)

The project performs the correct steps to do a blue/green or a rolling deployment into the environment selected. Student demonstrates the successful completion of chosen deployment methodology with screenshots.

Test the website

I took the ip address from the Loadbalancer: Screenshot 12 - Load Balancer I tested the Web App: Screenshot 13 - Test Web App
