|
|
<p>This section contains the most basic commands for getting a workload
|
|
running on your cluster.</p>
|
|
<ul>
|
|
<li><code>run</code> will start running 1 or more instances of a container image on your cluster.</li>
|
|
<li><code>expose</code> will load balance traffic across the running instances, and can create a HA proxy for accessing the containers from outside the cluster.</li>
|
|
</ul>
|
|
<p>Once your workloads are running, you can use the commands in the
|
|
<a href="#-strong-working-with-apps-strong-">WORKING WITH APPS</a> section to
|
|
inspect them.</p>

<p>Expose a resource as a new Kubernetes service. </p>
|
|
<p>Looks up a deployment, service, replica set, replication controller or pod by name and uses the selector for that resource as the selector for a new service on the specified port. A deployment or replica set will be exposed as a service only if its selector is convertible to a selector that service supports, i.e. when the selector contains only the matchLabels component. Note that if no port is specified via --port and the exposed resource has multiple ports, all will be re-used by the new service. Also if no labels are specified, the new service will re-use the labels from the resource it exposes. </p>
|
|
<p>Possible resources include (case insensitive): </p>
|
|
<p>pod (po), service (svc), replicationcontroller (rc), deployment (deploy), replicaset (rs)</p>

<p>When creating applications, you may have a Docker registry that requires authentication. In order for the nodes to pull images on your behalf, they have to have the credentials. You can provide this information by creating a dockercfg secret and attaching it to your service account.</p>

|
<p>Delete resources by filenames, stdin, resources and names, or by resources and label selector. </p>
|
|
<p>JSON and YAML formats are accepted. Only one type of the arguments may be specified: filenames, resources and names, or resources and label selector. </p>
|
|
<p>Some resources, such as pods, support graceful deletion. These resources define a default period before they are forcibly terminated (the grace period) but you may override that value with the --grace-period flag, or pass --now to set a grace-period of 1. Because these resources often represent entities in the cluster, deletion may not be acknowledged immediately. If the node hosting a pod is down or cannot reach the API server, termination may take significantly longer than the grace period. To force delete a resource, you must pass a grace period of 0 and specify the --force flag. </p>
|
|
<p>IMPORTANT: Force deleting pods does not wait for confirmation that the pod's processes have been terminated, which can leave those processes running until the node detects the deletion and completes graceful deletion. If your processes use shared storage or talk to a remote API and depend on the name of the pod to identify themselves, force deleting those pods may result in multiple processes running on different machines using the same identification which may lead to data corruption or inconsistency. Only force delete pods when you are sure the pod is terminated, or if your application can tolerate multiple copies of the same pod running at once. Also, if you force delete pods the scheduler may place new pods on those nodes before the node has released those resources and causing those pods to be evicted immediately. </p>
|
|
<p>Note that the delete command does NOT do resource version checks, so if someone submits an update to a resource right when you submit a delete, their update will be lost along with the rest of the resource.</p>

|
<p>Edit a resource from the default editor. </p>
|
|
<p>The edit command allows you to directly edit any API resource you can retrieve via the command line tools. It will open the editor defined by your KUBE _EDITOR, or EDITOR environment variables, or fall back to 'vi' for Linux or 'notepad' for Windows. You can edit multiple objects, although changes are applied one at a time. The command accepts filenames as well as command line arguments, although the files you point to must be previously saved versions of resources. </p>
|
|
<p>The files to edit will be output in the default API version, or a version specified by --output-version. The default format is YAML - if you would like to edit in JSON pass -o json. The flag --windows-line-endings can be used to force Windows line endings, otherwise the default for your operating system will be used. </p>
|
|
<p>In the event an error occurs while updating, a temporary file will be created on disk that contains your unapplied changes. The most common error when updating a resource is another editor changing the resource on the server. When this occurs, you will have to apply your changes to the newer version of the resource, or update your temporary saved copy to include the latest resource version.</p>

<p>The given node will be marked unschedulable to prevent new pods from arriving. 'drain' evicts the pods if the APIServer supports eviciton (<a href="http://kubernetes.io/docs/admin/disruptions/">http://kubernetes.io/docs/admin/disruptions/</a>). Otherwise, it will use normal DELETE to delete the pods. The 'drain' evicts or deletes all pods except mirror pods (which cannot be deleted through the API server). If there are DaemonSet-managed pods, drain will not proceed without --ignore-daemonsets, and regardless it will not delete any DaemonSet-managed pods, because those pods would be immediately replaced by the DaemonSet controller, which ignores unschedulable markings. If there are any pods that are neither mirror pods nor managed by ReplicationController, ReplicaSet, DaemonSet, StatefulSet or Job, then drain will not delete any pods unless you use --force. </p>
|
|
<p>'drain' waits for graceful termination. You should not operate on the machine until the command completes. </p>
|
|
<p>When you are ready to put the node back into service, use kubectl uncordon, which will make the node schedulable again. </p>
