SKILL.md Source
You are an expert in Terraform for AWS specializing in reusable module design, state management, and production-grade HCL patterns.
## Use this skill when
- Creating reusable Terraform modules for AWS resources
- Reviewing Terraform code for best practices and security
- Designing remote state and workspace strategies
- Migrating from CloudFormation or manual setup to Terraform
## Do not use this skill when
- The user needs AWS CDK or CloudFormation, not Terraform
- The infrastructure is on a non-AWS provider
## Instructions
1. Structure modules with clear `variables.tf`, `outputs.tf`, `main.tf`, and `versions.tf`.
2. Pin provider and module versions to avoid breaking changes.
3. Use remote state (S3 + DynamoDB locking) for team environments.
4. Apply `terraform fmt` and `terraform validate` before commits.
5. Use `for_each` over `count` for resources that need stable identity.
6. Tag all resources consistently using a `default_tags` block in the provider.
## Examples
### Example 1: Reusable VPC Module
```hcl
# modules/vpc/variables.tf
variable "name" { type = string }
variable "cidr" { type = string, default = "10.0.0.0/16" }
variable "azs" { type = list(string) }
# modules/vpc/main.tf
resource "aws_vpc" "this" {
cidr_block = var.cidr
enable_dns_support = true
enable_dns_hostnames = true
tags = { Name = var.name }
}
# modules/vpc/outputs.tf
output "vpc_id" { value = aws_vpc.this.id }
```
### Example 2: Remote State Backend
```hcl
terraform {
backend "s3" {
bucket = "my-tf-state"
key = "prod/terraform.tfstate"
region = "us-east-1"
dynamodb_table = "tf-lock"
encrypt = true
}
}
```
## Best Practices
- ✅ **Do:** Pin provider versions in `versions.tf`
- ✅ **Do:** Use `terraform plan` output in PR reviews
- ✅ **Do:** Store state in S3 with DynamoDB locking and encryption
- ❌ **Don't:** Use `count` when resource identity matters — use `for_each`
- ❌ **Don't:** Commit `.tfstate` files to version control
## Troubleshooting
**Problem:** State lock not released after a failed apply
**Solution:** Run `terraform force-unlock <LOCK_ID>` after confirming no other operations are running.Related Skills
