@alexcoderabbitai: Understood, I will perform a full review of the pull request. ✅ Actions performedFull review triggered. |
WalkthroughThis pull request involves the deletion of several GitHub Actions workflow files related to build checks, code style enforcement, dependency checks, and unit tests. Additionally, it introduces new Terraform configuration files that define infrastructure resources on AWS, including a VPC, subnets, security groups, and an EC2 instance. The changes also add output variables and new variable declarations for managing the infrastructure configuration. Changes

1-4: Remove empty line in output blockThe vpc_id output block contains an unnecessary empty line.
output "vpc_id" { value = aws_vpc.main.id - }
6-9: Consider marking instance_ip as sensitivePrivate IP addresses should typically be treated as sensitive information. Consider setting

1-48: Add backend configuration for state managementThe configuration is missing a backend block for state management. This is crucial for team collaboration and state locking.
Add this block at the beginning of the file:
terraform { backend "s3" { bucket = "your-terraform-state-bucket" key = "environment/terraform.tfstate" region = "us-west-2" encrypt = true dynamodb_table = "terraform-lock" } }Would you like me to help create an issue to track the implementation of proper state management?
