Klusterkit is a set of open source tools designed to simplify deployment and operations of highly-available, multi-master, production-grade Kubernetes clusters on on-premises, air-gapped environments.
Klusterkit is composed of three independent tools, that can be used separately, or in tandem:
- etcdadm – a CLI that simplifies operating an etcd cluster.
- nodeadm – a CLI node administration tool that complements kubeadm by deploying the dependencies that kubeadm requires.
- cctl – a cluster lifecycle management tool that adopts the Kubernetes community’s Cluster API and uses nodeadm and etcdadm to easily deploy and maintain highly-available Kubernetes clusters in on-premises, even air-gapped environments.
To start using Klusterkit and learn how the 3 tools work together, see the documentation on GitHub.
