Terraform Infrastructure Skill

Installation

The skill invokes the Terraform CLI. Install:

• macOS: brew tap hashicorp/tap && brew install hashicorp/tap/terraform
• Windows: choco install terraform or download from HashiCorp
• Linux (apt): Add HashiCorp repo then sudo apt update && sudo apt install terraform (see HashiCorp install)

Verify: terraform --version

Cheat Sheet & Best Practices

Workflow: terraform init → terraform fmt → terraform validate → terraform plan -out=tfplan → review → terraform apply tfplan. Use terraform show tfplan to inspect.

Hacks: Always run plan before apply; never apply blind. Use remote state (e.g. S3 + lock) for team work. Prefer -auto-approve only in CI with reviewed plans. Use terraform state list and terraform state show <resource> to debug. Use service accounts / workload identity in pipelines; avoid static keys.
