Pods: The Heart of Kubernetes

What is a Pod in Kubernetes?

A pod is the smallest deployable unit in Kubernetes, containing one or more containers Kubernetes manages workloads at the pod level that you can deploy.

Node is a physical or virtual machine that runs your pods and other Kubernetes components.

A node is a physical or virtual machine that runs pods and contains necessary components like the kubelet, kube-proxy, and container runtime.

The pod is a logical group of one or more containers sharing storage, network, and specifications.

Container wrapper→ It wraps one or more containers (usually Docker) that share resources and collaborate in perfect harmony.

Shared resources → Pods manage shared storage volumes, a distinct network IP, and localhost communication between containers.

Lifecycle management → Kubernetes automatically creates, destroys, and replaces pods to keep applications healthy and scalable.
