Simple DevOps Project by Farhaan Shamsee

Project Overview

1. This is a simple DevOps project on hosting an application on Tomcat Server.

2. In this I have used below tools and their functionality:

   • GIT/GITHUB : To integrate the source code with SCM tool and Jenkins.
   • Jenkins : As CI tool to instruct Ansible to build image based on the source code fetched from GITHUB.
   • Ansible: As CD tool with help of Jenkins to build Docker image and instruct Kubernetes to create deployment
   • Docker : To create image and store in hub.docker.com
   • Kubernetes : To create cluster and deploy the pods based on the Docker image
   • Terraform : To write infrastructure as code to quickly deploy the servers on AWS

3. The project is deployed on AWS cloud using services like EC2, S3, IAM, Route53 etc

Navigation through files

1. The repo has 4 folders with below functionality:

   • 1.Set Up Jenkins : To setup Jenkins server and integrate the Ansible Server
   • 2.Set Up Ansible : To set up Ansible server and integrate it with Kubernetes Cluster master node
   • 3.Set Up Kubernetes : To set up Kubernetes management Server which will create Kubernetes cluster using KOPS.
   • 4.Creating CI-CD : Contains steps that needs to be followed after setting up the servers like creating Jobs on Jenkins Server

2. To setup the insfrastructure I have used Terraform. Each folder has its own terraform script and it needs to be initiated from inside the folder. Each has its own User_Data script. Below are the commands that can be used to initiate terraform:

   #For running the script first time
   terraform init
   #To check the syntax and for any errors
   terraform plan
   #To create the resources
   terraform apply
   #To destroy the resources
   terraform destroy

3. Each folder has a seperate README file which can be used to understand the working of that configuration.
