🔧 Tools Used

• Terraform – To provision infrastructure (EC2 instances, security groups)
• Ansible – To configure the servers (install Docker and Jenkins)
• AWS EC2 – Virtual machines for deploying Jenkins and Docker

---

🚀 Getting Started

1. Clone the repository

git clone https://github.com/udaychopade27/devsecops-project.git
cd devsecops-project

🏗️ Step-by-Step Usage Guide

🌐 Step 1: Provision AWS Infrastructure using Terraform

Navigate to Terraform directory:

cd terraform

Initialize Terraform:

terraform init

Edit terraform.tfvars to provide your input variables:

aws_region       = "ap-south-1"
instance_type    = "t2.micro"
key_name         = "your-key-name"
public_key_path  = "~/.ssh/<privte-key.pem>"

Apply the configuration:

terraform apply

After successful apply, note down the public IPs of the two EC2 instances.

---

⚙️ Step 2: Configure Servers with Ansible

Navigate to the Ansible directory:

cd ansible

Edit inventory.ini with the public IPs of the provisioned instances:

[jenkins]
<jenkins_public_ip> ansible_user=ubuntu ansible_ssh_private_key_file=~/.ssh/id_rsa

[docker]
<docker_public_ip> ansible_user=ubuntu ansible_ssh_private_key_file=~/.ssh/id_rsa

Install Jenkins on the Jenkins EC2 instance:

ansible-playbook -i inventory.ini jenkins.yml

Install Docker on the Docker EC2 instance:

ansible-playbook -i inventory.ini docker.yml
