Terraform Best Practices

Essentials

• Use remote state and state locking
• Agree on naming convention
• Use tags

As a common sense, it’s highly recommended to reuse some matured modules such as VPC https://registry.terraform.io/

• Keep your providers, modules versioned properly
• Keep each module in a separate repo. Usually it depends on project size, and we can use monorepo or single modules repo as well.

• Use pre-commit https://pre-commit.com/#install https://github.com/antonbabenko/pre-commit-terraform

• Must have hooks:

  • terraform_fmt
  • terraform_validate
  • terraform_docs
  • terraform_tflint

• DRY (Don’t repeat yourself) to be continued…
