Kubestack Gitops Framework

Kubestack is a Gitops framework for managed Kubernetes services based on Terraform and Kustomize. It is designed to:

  • provide full testability by clearly separating infrastructure and application environments through the ops- and apps-cluster pair
  • ensure K8s cluster config, surrounding infrastructure (e.g. DNS, IPs) and cluster services (e.g. Ingress) are maintained together
  • unify application environments across cloud providers
  • enable a sustainable and fully automated Gitops workflow

For the easiest way to get started with Kubestack, visit the quickstart. The quickstart will bootstrap a user repository and a first cluster pair. See the tests for an example of how to extend this towards multi-cluster and/or multi-cloud.

Repository Layout

This repository holds Terraform modules in directories matching the respective provider name, e.g. aws, azurerm, google. Additionally common holds the modules that are used for all providers. Most notably the metadata module that ensures a consistent naming scheme and the cluster_services module which integrates Kustomize into the Terraform apply.

Each cloud provider specific module directory always has a cluster and a _modules directory. The cluster module is user facing and once Kubestack is out of beta the goal is to not change the module interface unless the major version changes. The cluster module then internally uses the module in _modules that holds the actual implementation.

The quickstart directory is home to the source for the zip files that are used to bootstrap the user repositories when following the quickstart documentation.

tests holds a set of happy path tests that also act as a example of how to do multiple cluster pairs across multiple clouds from one repository.
