How does the worker nodes in Kubernetes are related with master node?
Answers
Answer:
Kubernetes works by managing a cluster of compute instances and scheduling containers to run on the cluster based on the available compute resources and the resource requirements of each container. Containers are run in logical groupings called pods and you can run and scale one or many containers together as a pod.
Kubernetes control plane software decides when and where to run your pods, manages traffic routing, and scales your pods based on utilization or other metrics that you define. Kubernetes automatically starts pods on your cluster based on their resource requirements and automatically restarts pods if they or the instances they are running on fail. Each pod is given an IP address and a single DNS name, which Kubernetes uses to connect your services with each other and external traffic
Answer:
master node is a node which controls and manages a set of worker nodes (workloads runtime) and resembles a cluster in Kubernetes. A master node has the following components to help manage worker nodes:
Kube-APIServer, which acts as the frontend to the cluster. All external communication to the cluster is via the API-Server.
Kube-Controller-Manager, which runs a set of controllers for the running cluster. The controller-manager implements governance across the cluster.
Etcd, the cluster state database.
