Consequently, is Kubelet a pod?

The kubelet works in terms of a PodSpec. A PodSpec is a YAML or JSON object that describes a pod. The kubelet takes a set of PodSpecs that are provided through various mechanisms (primarily through the apiserver) and ensures that the containers described in those PodSpecs are running and healthy.

In this manner, what are Kubernetes constructs? A deployment is a Kubernetes construct that controls the creation and destruction of pods. This construct is particularly important because it is what keeps our application alive! A deployment is essentially a contract you make with Kubernetes that states the running conditions of your application.

Considering this, what are nodes in Kubernetes?

A Node is a worker machine in Kubernetes and may be either a virtual or a physical machine, depending on the cluster. Each Node is managed by the control plane. A Node can have multiple pods, and the Kubernetes control plane automatically handles scheduling the pods across the Nodes in the cluster.

What are objects in Kubernetes?

Kubernetes objects are persistent entities in the Kubernetes system. Kubernetes uses these entities to represent the state of your cluster. Specifically, they can describe: What containerized applications are running (and on which nodes) The resources available to those applications.

What are the components in master node?

The master server consists of various components including a kube-apiserver, an etcd storage, a kube-controller-manager, a cloud-controller-manager, a kube-scheduler, and a DNS server for Kubernetes services. Node components include kubelet and kube-proxy on top of Docker.

What are the components of a Kubernetes worker node?

Typically you have several nodes in a cluster; in a learning or resource-limited environment, you might have only one node. The components on a node include the kubelet, a container runtime, and the kube-proxy.
