Kubernetes Pods [1][2] 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 applykubectl create -f mypod.yml- Get a list of pods:
kubectl get pod MY_POD_NAMEkubectl delete pod MY_POD_NAMEkubectl top pod PODNAME- Get more information about a pod:
kubectl describe pod MY_POD_NAME
- List all container by pod:
kubectl get pods -o jsonpath='{range .items[*]}{"pod: "}{.metadata.name}{"\n"}{range .spec.containers[*]}{"\tname: "}{.name}{"\n\timage: "}{.image}{"\n"}{end}'
