Cluster API is a Kubernetes subproject providing declarative APIs and tooling for provisioning, upgrading, and operating multiple Kubernetes clusters. It uses Kubernetes-style APIs and a provider model to manage cluster infrastructure (VMs, networks, load balancers) consistently across environments.
Use cases
- provision kubernetes clusters declaratively
- manage lifecycle of multiple kubernetes clusters
- upgrade kubernetes clusters across cloud providers
- create consistent cluster deployments on aws azure vsphere
- bootstrap kubernetes control planes with kubeadm
- manage cluster infrastructure as kubernetes resources
When to choose
- you operate many kubernetes clusters across heterogeneous infrastructure
- you want declarative, Kubernetes-native cluster lifecycle management
- you need a provider-agnostic abstraction over cluster provisioning
When to avoid
- you only need a single cluster and can use kubeadm, kops, or a managed service
- your infrastructure has no Cluster API provider available
- you cannot run a management cluster
