What is POD in Kubernetes?

What is POD in Kubernetes? Pods are the smallest, most basic deployable objects in Kubernetes. A Pod represents a single instance of a running process in your cluster. Pods contain one or more containers, such as Docker containers. When a Pod runs multiple containers, the containers are managed as a single entity and share the Pod’s resources.

What is POD and container in Kubernetes? Unlike other systems you may have used in the past, Kubernetes doesn’t run containers directly; instead it wraps one or more containers into a higher-level structure called a pod. Any containers in the same pod will share the same resources and local network. Pods are used as the unit of replication in Kubernetes.

What is meant by POD in Kubernetes? A pod is the smallest execution unit in Kubernetes. A pod encapsulates one or more applications. Pods are ephemeral by nature, if a pod (or the node it executes on) fails, Kubernetes can automatically create a new replica of that pod to continue operations.

What is difference between POD and container? “A container runs logically in a pod (though it also uses a container runtime); A group of pods, related or unrelated, run on a cluster. A pod is a unit of replication on a cluster; A cluster can contain many pods, related or unrelated [and] grouped under the tight logical borders called namespaces.”
