Public Modules

Terraform modules can be published on the Terraform Registry. This is the official registry of Terraform modules.

Modules can be of three types:

• Official modules: published by HashiCorp
• Verified modules: published by a verified publisher
• Community modules: published by anyone

When using the search bar on the Terraform registry only verified and official modules are shown by default.

Using modules

To use a module, add a module block to the configuration file:

module "vpc" {
  source = "terraform-aws-modules/vpc/aws"
  version = "2.9.0"
  # ...
}

terraform init will download the module and its dependencies.

Publishing modules

• The terraform registry is a public index of modules
• To publish a module, it has to be published to a git repository (mainly GitHub) following a specific structure for the naming of the repository and the files
• When working with github, the account can be integrated with the terraform registry to automatically publish modules when a new release is created.
