Terraform Module to provision a GitHub Repository with advanced settings.

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform
Example of running atmos to manage infrastructure from our Quick Start tutorial.

Introduction

Terraform Module to provision a GitHub Repository with advanced settings:

  • Repository
  • Environments
  • Deploy Keys
  • Rulesets
  • Secrets
  • Variables
  • Custom Properties
  • Webhooks
  • Autolink References
  • Labels
  • Collaborators

Usage

For a complete example, see examples/complete.

module "github_repository" {
  source  = "cloudposse/repository/github"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"

  name = "my-repository"
  description = "My repository"
  visibility = "public"
  auto_init = true
  has_issues = true
  has_projects = true
  has_wiki = true
  has_downloads = true
  is_template = false
}

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Examples

Here is an example of using this module:

Requirements

Name Version
terraform >= 1.0
github >= 6.6.0

Inputs

Name Description Type Default Required
additional_tag_map Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id.
This is for some rare cases where resources want additional configuration of tags
and therefore take a list of maps with tag key, value, and additional configuration.		 map(string) {} no
allow_auto_merge Allow auto merge bool false no
allow_merge_commit Allow merge commit bool true no
allow_rebase_merge Allow rebase merge bool true no
allow_squash_merge Allow squash merge bool true no
allow_update_branch Allow updating the branch bool false no
archive_on_destroy Archive the repository on destroy bool false no
archived Whether the repository is archived bool false no
attributes ID element. Additional attributes (e.g. workers or cluster) to add to id,
in the order they appear in the list. New attributes are appended to the
end of the list. The elements of the list are joined by the delimiter
and treated as a single ID element.		 list(string) [] no
auto_init Auto-initialize the repository bool false no
autolink_references Autolink references 
map(object({
    key_prefix          = string
    target_url_template = string
    is_alphanumeric     = optional(bool, false)
  }))
 {} no
context Single object for setting entire context at once.
See description of individual variables for details.
Leave string and numeric variables as null to use default value.
Individual variable settings (non-null) override settings in context object,
except for attributes, tags, and additional_tag_map, which are merged.		 any

  }))
 {} no

    key       = string
    read_only = optional(bool, false)

description Description of the repository string null no
descriptor_formats Describe additional descriptors to be output in the descriptors output map.
Map of maps. Keys are names of descriptors. Values are maps of the form
{<br/> format = string<br/> labels = list(string)<br/>}
(Type is any so the map values can later be enhanced to provide additional options.)
format is a Terraform format string to be passed to the format() function.
labels is a list of labels, in order, to pass to format() function.
Label values will be normalized before being passed to format() so they will be
identical to how they appear in id.
Default is {} (descriptors output will be empty).		 any {} no
enable_vulnerability_alerts Enable vulnerability alerts bool true no
enabled Set to false to prevent the module from creating any resources bool null no
environment ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT' string null no

Running Terraform Tests

We use Atmos to streamline how Terraform tests are run. It centralizes configuration and wraps common test workflows with easy-to-use commands.

All tests are located in the test/ folder.

Under the hood, tests are powered by Terratest together with our internal Test Helpers library, providing robust infrastructure validation.

Setup dependencies:

To run tests:

  • Run all tests: 
    atmos test run
  • Clean up test artifacts: 
    atmos test clean
  • Explore additional test options: 
    atmos test --help

The configuration for test commands is centrally managed. To review what's being imported, see the atmos.yaml file.

Learn more about our automated testing in our documentation or implementing custom commands with atmos.
