--- --- * TOC {:toc} A pod is a group of containers that are scheduled onto the same host. Pods serve as units of scheduling, deployment, and horizontal scaling/replication. Pods share fate, and share some resources, such as storage volumes and IP addresses. ## Creating a pod Single-container pods can be created with the `run` command. The pod's properties are specified with flags on the command line. The `run` command creates a replication controller to monitor the pod(s). The controller watches for failed pods and will start up new pods as required to maintain the specified number. Note: If you don't want a replication controller to monitor your pod (e.g. your pod is writing non-persistent data which won't survive a restart, or your pod is intended to be very short-lived), you can [create a pod directly with the `create` command](/docs/user-guide/pods/multi-container/). To create a pod using the `run` command: ```shell $ kubectl run NAME --image=image [--port=port] [--replicas=replicas] [--labels=key=value,key=value,...] ``` Where: * `NAME` (required) is the name of the container to create. This value is also applied as the name of the replication controller, and as the prefix of the pod name. For example: ```shell $ kubectl run example --image=nginx replicationcontroller "example" created $ kubectl get pods NAME READY STATUS RESTARTS AGE example-xypvc 1/1 Running 0 13s ``` * `--image=IMAGE` (required) is the Docker container image to use for this container. * `--port=PORT` is the port to expose on the container. * `--replicas=NUM` is the number of replicated pods to create. If not specified, one pod will be created. * `--labels=key=value` specifies one or more labels to attach to the pod. In addition to any labels specified here, `run` attaches a label of the format `run=NAME`. This is used by the replication controller to target the pods created by the command. There are additional flags that can be specified. For a complete list, run: $ kubectl run --help ## Viewing a pod {% include_relative _viewing-a-pod.md %} ## Deleting a pod If your pod was created using the `run` command, kubernetes creates a [replication controller](/docs/user-guide/replication-controller/) to manage the pod. Pods managed by a replication controller are rescheduled if they go away, including being deleted by `kubectl delete pod`. To permanently delete the pod, delete its replication controller. First, find the controller's name: ```shell $ kubectl get rc CONTROLLER CONTAINER(S) IMAGE(S) SELECTOR REPLICAS example example busybox run=example 1 ``` Then, `delete` the controller: ```shell $ kubectl delete rc CONTROLLER_NAME ```
