What is Pod in kubernetes. Exaplin in 15 points with image as an example

  • Pod is the atomic unit of scheduler in K8s.
  • Pods contains one or more containers, at least one.
  • K8s(kubelet) will instantiate pods.
  • Pod is running as long the container inside is running.
  • Life cycle of pod – Pending, Running, Succeded/ Failed
  • Pods will communicate with each other through a pod network – inter pod communication.
  • If the pods are in same node, it will communicate via localhost.
  • We can’t get the same pod again. We can get the similar pod.
  • Pods run an application, access through network.
  • The most recommended design to have only one container in a pod.
