- The kubelet is like the captain on the ship.
- Ones responsible for doing all of the paperwork to become part of the cluster.
- Sole point of contact for the Master Ship.
- They load and unload containers, instructed by the scheduler on the Master Node.
- They also send back reports at regular intervals on the status of the ship.
- The
kubelet in the Kubernetes Worker Node, registers the node in the Kubernetes Cluster.
- When the
kubelet receives a request to load a pod, it goes to the runtime engine (for example Docker) and pulls the required image to run an instance.
- The
kubelet then continues to monitor the state of the pod and the containers within it and reports to the kube-apiserver on a timely basis.
- How do you install a
kubelet?
- If you use the
kubeadm tool, it does not automatically deploy the kubelet.
- Must always manually install the
kubelet on your worker nodes.
- Download the installer, extract it and run it as a service.
- You can view the
kubelet and its options by running ps -aux | grep kubelet on the Worker Nodes.
