Kubernetes Worker Node Components Important Terminologies
Worker nodes are the node where the application actually runs in a kubernetes cluster, it is also known as a minion. These worker nodes are controlled by the master node using Kublet processes.
- kubelet
- kube-Proxy
- Container runtime
Kubelet
The main node agent, known as Kubelet, operates on each node and reads the container manifests to make sure that the containers are active and in good condition. It ensures that pods of containers are operating. Containers that weren’t made by Kubernetes are not managed by the kubelet.
Kube-Proxy
By managing network rules on the host and managing connections, kube-proxy supports the kubernetes service abstraction. On nodes, Kube-proxy keeps track of network rules. Network connectivity to your pod is permitted by these network rules from both inside and outside of your cluster. Having a network proxy and load balancer for the service on a single worker node is beneficial to us.
Container Runtime
To process commands from the master server to run containers, each node needs a container runtime, such as Docker, containerd, or another container runtime.
