About kubeadm, kubelet, kubectl, and Control Plane in Kubernetes with examples.
kubeadm: Kubeadm is a command-line tool designed to simplify the process of setting up and managing a Kubernetes cluster. It is primarily used for bootstrapping a new cluster, initializing control plane nodes, and joining worker nodes to the cluster. Kubeadm automates many of the manual tasks involved in setting up a Kubernetes cluster, making it…
How to work the kube-scheduler
The Kubernetes Scheduler (kube-scheduler) is responsible for assigning pods to nodes in the cluster based on various factors such as resource requirements, affinity/anti-affinity rules, node capacity, and user-defined constraints. Here’s how the kube-scheduler works: By following this process, the kube-scheduler ensures efficient and optimal utilization of cluster resources while meeting the requirements and constraints specified…
How to work Kube-Controller
Kubernetes controllers are control loops that watch the state of your cluster’s resources and take corrective action to move the current state towards the desired state. Here’s how Kubernetes controllers work: In summary, Kubernetes controllers play a crucial role in ensuring that the state of resources in the cluster remains consistent with their desired state.…
