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.
