Simple DevOps Project by Farhaan Shamsee

Project Overview

This is a simple DevOps project on hosting an application on Tomcat Server.
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
The project is deployed on AWS cloud using services like EC2, S3, IAM, Route53 etc

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