S3 Buckets

List all S3 buckets needed:

• Bucket 1: [name and purpose, e.g., "app-assets for static files"]
  • Versioning: [Enabled / Disabled]
  • Public Access: [Block / Allow]
  • Lifecycle Rules: [Yes / No]
• Bucket 2: [name and purpose]
  • [Configuration details]

Additional AWS Resources (Optional)

• IAM Policies: [Describe custom policies needed]
• Security Groups: [List all security groups beyond EC2]

Tags

Standard tags to apply to all resources:

• Project: [project name]
• Environment: [environment]
• ManagedBy: Terraform
• [Additional custom tags]

Outputs Required

What values should be output:

• VPC ID
• Subnet IDs
• EC2 Instance IPs
• RDS Endpoint
• S3 Bucket Names
• Load Balancer DNS
• [Additional outputs]

Deliverables

Generate the following Terraform files:

1. main.tf - Provider configuration, backend setup, data sources
2. variables.tf - All input variables with descriptions and defaults
3. outputs.tf - All output values
4. vpc.tf - VPC, subnets, internet gateway, NAT gateway, route tables
5. ec2.tf - EC2 instances, security groups, key pairs, user data
6. rds.tf - RDS instance, subnet group, parameter group, security group
7. s3.tf - S3 buckets with versioning, encryption, and access policies
8. iam.tf - IAM roles, policies, and instance profiles
9. terraform.tfvars.example - Example variable values

All code should:

• Follow Terraform best practices
• Use variables for all configurable values
• Include descriptive comments
• Implement proper security (encryption, private subnets, security groups)
• Use remote state backend (S3)
• Include proper resource dependencies
• Add appropriate tags to all resources

Generate production-ready Terraform code ready to run with terraform init, terraform plan, and terraform apply.
