A cheaper, DIY Kuberentes cluster based on spot instances
Services as EKS, AKS or GKE are quite expensive. The pricing strategy that most cloud providers apply is to bill the managed Kubernetes controlplane and the individual worker nodes attached to the system and the resources those virtual machines use.
| Cloud provider | Price |
|---|---|
| DigitalOcean | 12$/month/node |
| AWS EKS | $0.10/cluster/hour + Compute pricing |
| Azure AKS | $0.10/cluster/hour + Compute pricing |
| Google GKE | $0.10/cluster/hour + Compute pricing |
Only the managed controlplane provided by the major cloud providers add up to around 75$/month without taking in consideration the compute pricing of the worker nodes.
Spot k8s aims to provision a Kubernetes cluster utilising your choice of base compute power and a series of disposable spot instances for worker nodes.
This project should not be viewed as a production grade Kubernetes cluster set-up automation tool. It aims to provide a cheap and easy way of setting up a Kubernetes cluster for learning purposes.
The target audience for this project is anybody who wants to learn Kubernetes and needs a cheap playground that can be used without worring about messing up your current environment.
I started this project because I wanted to learn more about IaaC, more specific Terraform. My end goal was to create a one-line command set-up automation tool that can set-up the entire infrastructure required by a Kubernetes cluster while aiming to lower the cost as much as possible.
