Devops-Project

This project is a Terraform-based infrastructure setup for a DevOps environment. It includes modules for various AWS resources such as VPC, subnets, security groups, load balancers, and more. Additionally, it uses Ansible for configuration management.

Prerequisites

• Terraform installed
• AWS CLI configured with appropriate credentials
• Ansible installed
• Docker installed

Setup

1. Clone the repository:

   git clone https://github.com/AyaOmer/Devops-Project.git
   cd Devops-Project

2. Initialize Terraform:

   terraform init

3. Review and modify terraform.tfvars to match your requirements:

   project_name = "esmael"
   ami_id       = "ami-0e86e20dae9224db8"
   instance_type = "t2.micro"
   instance_name = "Terraform"
   lb_name       = "my-load-balancer"
   key_name      = "key-pair"
   user_data = <<-EOF
                 #!/bin/bash
                 sudo apt update
                 sudo apt install -y software-properties-common python3-pip
                 pip3 install ansible
                 echo "Welcome to Esmael's private_instances. Ansible has been installed." > /home/ubuntu/welcome.txt
                 EOF
   bastion_ingress_rules = [
     {
       from_port   = 22
       to_port     = 22
       protocol    = "tcp"
       cidr_blocks = ["0.0.0.0/0"]
     }
   ]
   nginx_ingress_rules = [
     {
       from_port   = 80
       to_port     = 80
       protocol    = "tcp"
       cidr_blocks = ["0.0.0.0/0"]
     }
   ]
   custom_ingress_rules = [
     {
       from_port   = 3000
       to_port     = 3000
       protocol    = "tcp"
       cidr_blocks = ["0.0.0.0/0"]
     },
     {
       from_port   = 8084
       to_port     = 8084
       protocol    = "tcp"
       cidr_blocks = ["0.0.0.0/0"]
     },
     {
       from_port   = 50000
       to_port     = 50000
       protocol    = "tcp"
       cidr_blocks = ["0.0.0.0/0"]
     },
     {
       from_port   = 8000
       to_port     = 8000
       protocol    = "tcp"
       cidr_blocks = ["0.0.0.0/0"]
     }
   ]

4. Apply the Terraform configuration:

   terraform apply

   Confirm the apply with yes.

Ansible Configuration

The Ansible playbook is located in the ansible directory. It installs Docker and Docker Compose on the local machine.

• Run the Ansible playbook:

  cd ansible
  ./script.sh

Docker Configuration

The Dockerfile is located in the Docker directory. It builds and serves a React application using Nginx.

• Build the Docker image:

  docker build -t your-image-name Docker/

• Run the Docker container:

  docker run -p 80:80 your-image-name

Outputs

The Terraform configuration provides the following outputs:

• bastion_public_ip: The public IP of the bastion host.
