In the reference section, you can find reference documentation for Kubernetes APIs, CLIs, and tools, as well as our glossary and design docs.

API References

CLI References

  • kubectl - Runs commands against Kubernetes clusters.
  • kube-apiserver - REST API that validates and configures data for API objects such as pods, services, replication controllers.
  • kube-proxy - Can do simple TCP/UDP stream forwarding or round-robin TCP/UDP forwarding across a set of backends.
  • kubelet - The primary "node agent" that runs on each node. The kubelet takes a set of PodSpecs and ensures that the described containers are running and healthy.
