Terraform EKS Workspace Module

This module creates and configures a new GitHub repository for EKS cluster configuration, based on a template repository. It uses the terraform-github-repo module to manage the repository and its configuration.

Features

• Creates a new GitHub repository from a template
• Configures repository settings and permissions
• Injects configuration files using managed_extra_files
• Sets up branch protection and access controls
• Configures CODEOWNERS and other repository files

Usage

module "eks_workspace" {
  source = "HappyPathway/repo/github"

  repository_name        = "my-eks-cluster"
  repository_description = "EKS Cluster configuration for my-eks-cluster"
  
  # Optional: Override template repository settings
  template_repo_org  = "my-org"
  template_repo_name = "custom-template"

  # Configuration for the EKS cluster
  cluster_config = {
    cluster_name    = "my-eks-cluster"
    cluster_version = "1.27"
    region          = "us-east-1"
    # Add other cluster configuration options
  }
}

Requirements

• Terraform >= 1.0.0
• GitHub provider configured with appropriate permissions
• Access to the template repository

Inputs

Name	Description	Type	Default	Required
repository_name	Name of the repository to create	string	-	yes
repository_description	Description of the repository	string	null	no
template_repo_org	Organization containing the template repository	string	"HappyPathway"	no
template_repo_name	Name of the template repository	string	"template-eks-cluster"	no
cluster_config	Configuration for the EKS cluster	map(any)	{}	yes

Outputs

Name	Description
repository_url	URL of the created repository
repository_full_name	Full name of the repository (org/name)
git_clone_url	Git clone URL of the repository

Implementation Details

The module implements the following workflow:

1. Creates a new repository using the terraform-github-repo module
2. Uses the specified template repository (default: HappyPathway/template-eks-cluster)
3. Injects the cluster configuration as a config.json file using managed_extra_files
4. Sets up repository settings, branch protection, and access controls
5. Configures CODEOWNERS and other repository files

This replaces the previous Lambda-based automation with a pure Terraform implementation, making it easier to manage and maintain.

Migration Notes

This module replaces the previous Lambda-based automation (template-automation-lambda) with the following improvements:

• Pure Terraform implementation - no Lambda functions to maintain
• Direct integration with terraform-github-repo module
• Configuration managed through Terraform variables
• Simplified workflow and reduced complexity
• Better version control and change tracking
