Prerequisites

• Terraform v1.0+
• Configured AWS CLI
• AWS Account permissions (VPC, EC2, S3, DynamoDB)

Getting Started

1. Clone repository:

git clone https://github.com/yourusername/tf-aws-infra.git
cd tf-aws-infra

2. Initialize Terraform:

bashCopyterraform init

3. Configure variables in terraform.tfvars:

hclCopyaws_region = "us-east-1"
environment = "dev"

SSL Certificate Import for DEMO Environment

To import your third-party SSL certificate (from Namecheap or another vendor) into AWS Certificate Manager (ACM), run:

aws acm import-certificate \
  --certificate file://path/to/certificate.pem \
  --private-key file://path/to/private-key.pem \
  --certificate-chain file://path/to/certificate-chain.pem \
  --region <AWS_REGION>

Use the returned Certificate ARN in your load balancer configuration.

4. Plan and apply:

terraform plan -var-file="terraform.tfvars"
terraform apply -var-file="terraform.tfvars"
