Terraform Development
Safety Rules
NEVER run without user confirmation:
terraform applyterraform destroyterraform import
ALWAYS run first:
terraform planterraform validate
Workflow
┌────────────────────────────────────────────────┐
│ VALIDATE → PLAN → REVIEW → APPLY │
└────────────────────────────────────────────────┘
Step 1: Validate
terraform init
terraform validate
terraform fmt -check
Step 2: Plan
terraform plan -out=tfplan
Show plan to user and wait for confirmation.
Step 3: Apply (only after explicit approval)
terraform apply tfplan
Linting
# Format check
terraform fmt -check -recursive
# TFLint
tflint --recursive
# Checkov security scanning
checkov -d .
