Terraform AWS Web Application Deployment

This project automates the deployment of a web application environment on AWS using Terraform. The infrastructure includes a Virtual Private Cloud (VPC) with multiple subnets, security groups, EC2 instances for Jenkins and Docker, an Application Load Balancer (ALB), and an Elastic Container Registry (ECR).

The architecture comprises:

• VPC: Configured with public and private subnets to host resources securely.
• Security Groups: Defined to control inbound and outbound traffic to AWS resources.
• EC2 Instances:
  • Jenkins Server: For continuous integration and deployment tasks.
  • Docker Host: To run containerized applications.
• Application Load Balancer (ALB): Distributes incoming application traffic across multiple targets, ensuring high availability.
• Elastic Container Registry (ECR): A fully managed Docker container registry that makes it easy to store, manage, and deploy Docker container images.

Prerequisites

Before deploying this infrastructure, ensure you have the following:

• AWS Account: Active account with sufficient permissions to create the necessary resources.
• Terraform: Installed on your local machine.
• AWS CLI: Configured with appropriate access credentials.
• SSH Key Pair: An existing key pair in the target AWS region for EC2 instance access.

Deployment Steps

1. Clone the Repository:

   git clone https://github.com/Levi-Michael/terraform-aws-web-app.git
   cd terraform-aws-web-app

2. Initialize Terraform:

   terraform init

3. Upgrade Terraform Providers (if necessary):

   terraform init -upgrade

4. Review the Execution Plan:

   terraform plan

5. Apply the Configuration:

   terraform apply

   Note: Review the changes and confirm the application when prompted.

Post-Deployment

After deployment:

• Access Jenkins: Use the public DNS of the Jenkins EC2 instance to access the Jenkins dashboard.
• Deploy Applications: Utilize the Docker host and ECR to manage and deploy your containerized applications.

Cleanup

To avoid incurring unnecessary charges, destroy the infrastructure when it's no longer needed:

terraform destroy

Ensure that you have backups of any important data before destroying the infrastructure.
