# Terraform Kubernetes Multi-Cloud

Terraform code for creating a handful of simple managed Kubernetes clusters on multiple public cloud platforms.

_Managed_ in this context means the master nodes (= control plane) are managed by the cloud platform provider. We only create the service, the worker nodes and the bare minimum of everything else to get a working K8s cluster.

ℹ️  This is for demonstration and/or learning purposes.

ℹ️  Please do not use this in production.

## Public Cloud Platforms

* ✅ Alibaba Cloud _"Managed Kubernetes Cluster Service"_ **(ACK)**

* ✅ Amazon Web Services _"Elastic Kubernetes Engine"_ **(EKS)**

* ✅ Digital Ocean _"Kubernetes"_ **(DOK)**

* ✅ Google Cloud Platform _"Google Kubernetes Engine"_ **(GKE)**

* ✅ Microsoft Azure _"Azure Kubernets Service"_ **(AKS)**

* ✅ Oracle Cloud Infrastructure _"Container Engine for Kubernetes"_ **(OKE)**

* 🔜 IBM Cloud _Kubernetes Service"_ **(IKS)** ([when their Terraform provider is 0.12-ready](https://github.com/IBM-Cloud/terraform-provider-ibm/pull/423))

## Features

* Fully working K8s Clusters

* Terraform 0.12 code

* By default creates small node configurations (low costs!)

* Outputs ready-to-use kubeconfig files at the end

* 2-3 worker nodes

## Requirements

* Terraform >= 0.12.x

* You need to have an account on the cloud platforms (of course).
