CCoE Module - GitHub

This Terraform module allows you to manage your GitHub configuration in code.

It supports the creation of:

• Repositories
• Branch protection rules
• Actions permissions
• Teams
• Teams permissions

By using this module you ensure that:

• All repos are built to a standard pattern
• Repos are always delegated to teams
• Branch protection rules are configured in a standardised way
• GitHub actions permissions are configured to a baseline

Example Usage

The module can be called from your Terraform as shown in this example below:

module "example" {
  source = "github.com/UKHomeOffice/ccoe-module-github?ref=v1.1.0"
