Complete Workflow

From local development to critical production environment. The Kubestack framework combines a complete GitOps workflow with a delightful developer experience for teams.

Reliable Automation

Configuration inheritance and GitOps automation to validate and promote changes between environments allows teams of any size to safely collaborate on infrastructure changes.

Inheritance Model >>

Native Integration

Kubestack integrates cluster infrastructure and services into the Terraform ecosystem using modules and providers so that platform teams can maintain the entire Kubernetes stack as one.

Cluster modules >>
Cluster service modules >>
# cluster modules provision AKS, EKS or GKE Kubernetes
module "gke_example" {
  # ...
}
# cluster service modules provision Kubernetes services
provider "kustomization" {
  alias = "gke_example"
  kubeconfig_raw = module.gke_example.kubeconfig
}
module "gke_example_prometheus" {
  providers = {
    kustomization = kustomization.gke_example
  }
  # ...
}

Why Kubestack

The best teams use frameworks to develop better applications faster. Using a framework makes it possible to skip the boilerplate, and focus on what matters.

But why do you still write infrastructure as code from scratch to automate your Kubernetes platform?

Kubestack is the Terraform framework that we always dreamed of to define and maintain custom platforms stacks.

Move fast without breaking things

Increase Speed

Adapt the tried and tested pull-request and peer-review based workflow to efficiently manage changes with your team.

Fast track the boilerplate and focus on what's important with reusable Terraform modules for cluster infrastructure and services.

Reduce long-term effort by minimizing the bespoke infrastructure code you have to maintain yourself.

Reduce Risk

Limit the blast-radius through independent environments and unlock simultaneous infrastructure and application changes.

Avoid configuration drift on mission critical environments leveraging inheritance to make differences explicit.

Rely on an integrated GitOps process designed to provide feedback and validate changes before they are promoted.

Save Costs

Leverage auto-updating localhost development environments to quickly iterate on Kubernetes platform manifests.

Scale, improve availability or avoid lock-in using fully supported multi-cluster, multi-region and multi-cloud deployments.

Unify the application runtime environments of your clusters using the most popular cloud-native solutions.
