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.
- ✅ 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)
- 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
- Terraform >= 0.12.x
- You need to have an account on the cloud platforms (of course).
