Catalog

Launch the user interface for searching and managing your module catalog.

terragrunt catalog <repo-url> [--no-include-root] [--root-file-name]

If <repo-url> is provided, the repository will be cloned into a temporary directory, otherwise:

1. The repository list are searched in the config file terragrunt.hcl. if terragrunt.hcl does not exist in the current directory, the config are searched in the parent directories.
2. If the repository list is not found in the configuration file, the modules are looked for in the current directory.

An example of how to define the optional default template and the list of repositories for the catalog command in the terragrunt.hcl configuration file:

terragrunt.hcl

catalog {
  default_template = "git@github.com/acme/example.git//path/to/template"  # Optional default template to use for scaffolding
  urls = [
    "relative/path/to/repo", # will be converted to the absolute path, relative to the path of the configuration file.
    "/absolute/path/to/repo",
    "github.com/gruntwork-io/terraform-aws-lambda", # url to remote repository
    "http://github.com/gruntwork-io/terraform-aws-lambda", # same as above
  ]
}

This will recursively search for OpenTofu/Terraform modules in the root of the repo and the modules directory and show a table with all the modules. You can then:

1. Search and filter the table: / and start typing.
2. Select a module in the table: use the arrow keys to go up and down and next/previous page.
3. See the docs for a selected module: ENTER.
4. Use terragrunt scaffold to render a terragrunt.hcl for using the module: S.

Custom templates for scaffolding

Terragrunt has a basic template built-in for rendering terragrunt.hcl files, but you can provide your own templates to customize how code is generated! Scaffolding is done via boilerplate, and Terragrunt allows you to specify custom boilerplate templates via two mechanisms while using catalog:

1. You can define a custom Boilerplate template in a .boilerplate sub-directory of any OpenTofu/Terraform module.
2. You can specify a custom Boilerplate template in the catalog configuration using the default_template option.

Scaffolding Flags

The following catalog flags control behavior of the underlying scaffold command when the S key is pressed in a catalog entry:

• --no-include-root - Do not include the root configuration file in any generated terragrunt.hcl during scaffolding.
• --root-file-name - The name of the root configuration file to include in any generated terragrunt.hcl during scaffolding. This value also controls the name of the root configuration file to search for when trying to determine Catalog urls.
