pre-commit-terraform hook

Several pre-commit hooks to keep Terraform configurations (both *.tf and *.tfvars) in a good shape:

• terraform_fmt - Rewrites all Terraform configuration files to a canonical format.
• terraform_validate_no_variables - Validates all Terraform configuration files without checking whether all required variables were set.
• terraform_validate_with_variables - Validates all Terraform configuration files and checks whether all required variables were specified.
• terraform_docs - Inserts input and output documentation into README.md.

Notes about hooks

1. terraform_validate_no_variables and terraform_validate_with_variables will not work if variables are being set dynamically (eg, when using Terragrunt). Use terragrunt validate command instead.

2. terraform_docs will insert/update documentation generated by terraform-docs between markers - <!-- BEGINNING OF PRE-COMMIT-TERRAFORM DOCS HOOK --> and <!-- END OF PRE-COMMIT-TERRAFORM DOCS HOOK --> if they are present in README.md. Make sure that terraform-docs is installed.

Example

.pre-commit-config.yaml:

- repo: git://github.com/antonbabenko/pre-commit-terraform
  rev: v1.7.3
  hooks:
    - id: terraform_fmt
    - id: terraform_docs

Enjoy the clean and documented code!
