Kubernetes Pods are the smallest deployable units that allows to deploy one or multiple containers as a single atomic unit. Pods are defined using YAML files and applied with kubectl apply command.

• kubectl create -f mypod.yml
• Get a list of pods:

kubectl get pods

• kubectl get pod MY_POD_NAME
• kubectl delete pod MY_POD_NAME
• kubectl top pod PODNAME
• Get more information about a pod:

kubectl describe pod MY_POD_NAME

See also ReplicaSet concept.
