In this article on series basics on Kubernetes, we are going to talk about what is the component of nodes in Kubernetes and what are their tasks. Before that, if you have not read about the control plane in Kubernetes, you can read about it below.
Node components:
Node components are the process that will run on nodes to facilitate the working of Kubernetes. The components are kube-proxy, kubelet, and container runtime.
Kube-proxy:
Kube proxy helps in routing the traffic with help of iptables to the exact location when you call any service. It makes changes in iptables to help the packet reach a destination when a service is called. If you want to read more about it you can read the below article.
