# GETTING STARTED

This section contains the most basic commands for getting a workload running on your cluster.

- `run` will start running 1 or more instances of a container image on your cluster.
- `expose` will load balance traffic across the running instances, and can create a HA proxy for accessing the containers from outside the cluster.

Once your workloads are running, you can use the commands in the WORKING WITH APPS section to inspect them.

# run

> Start a single instance of nginx.

    kubectl run nginx --image=nginx

> Start a single instance of hazelcast and let the container expose port 5701 .

    kubectl run hazelcast --image=hazelcast --port=5701

> Start a single instance of hazelcast and set environment variables "DNS_DOMAIN=cluster" and "POD_NAMESPACE=default" in the container.

    kubectl run hazelcast --image=hazelcast --env="DNS_DOMAIN=cluster" --env="POD_NAMESPACE=default"

> Start a single instance of hazelcast and set labels "app=hazelcast" and "env=prod" in the container.

    kubectl run hazelcast --image=nginx --labels="app=hazelcast,env=prod"

> Start a replicated instance of nginx.

    kubectl run nginx --image=nginx --replicas=5

> Dry run. Print the corresponding API objects without creating them.

    kubectl run nginx --image=nginx --dry-run

> Start a single instance of nginx, but overload the spec of the deployment with a partial set of values parsed from JSON.

    kubectl run nginx --image=nginx --overrides='{ "apiVersion": "v1", "spec": { ... } }'

> Start a pod of busybox and keep it in the foreground, don't restart it if it exits.

    kubectl run -i -t busybox --image=busybox --restart=Never

> Start the nginx container using the default command, but use custom arguments (arg1 .. argN) for that command.

    kubectl run nginx --image=nginx -- <arg1> <arg2> ... <argN>

> Start the nginx container using a different command and custom arguments.

    kubectl run nginx --image=nginx --command -- <cmd> <arg1> ... <argN>

> Start the perl container to compute π to 2000 places and print it out.

    kubectl run pi --image=perl --restart=OnFailure -- perl -Mbignum=bpi -wle 'print bpi(2000)'

> Start the cron job to compute π to 2000 places and print it out every 5 minutes.

    kubectl run pi --schedule="0/5 * * * ?" --image=perl --restart=OnFailure -- perl -Mbignum=bpi -wle 'print bpi(2000)'

Create and run a particular image, possibly replicated.

Creates a deployment or job to manage the created container(s).

# expose

> Create a service for a replicated nginx, which serves on port 80 and connects to the containers on port 8000.

    kubectl expose rc nginx --port=80 --target-port=8000

> Create a service for a replication controller identified by type and name specified in "nginx-controller.yaml", which serves on port 80 and connects to the containers on port 8000.

    kubectl expose -f nginx-controller.yaml --port=80 --target-port=8000

> Create a service for a pod valid-pod, which serves on port 444 with the name "frontend"

    kubectl expose pod valid-pod --port=444 --name=frontend

> Create a second service based on the above service, exposing the container port 8443 as port 443 with the name "nginx-https"

    kubectl expose service nginx --port=443 --target-port=8443 --name=nginx-https

> Create a service for a replicated streaming application on port 4100 balancing UDP traffic and named 'video-stream'.

    kubectl expose rc streamer --port=4100 --protocol=udp --name=video-stream

> Create a service for a replicated nginx using replica set, which serves on port 80 and connects to the containers on port 8000.

> Create a service for an nginx deployment, which serves on port 80 and connects to the containers on port 8000.

    kubectl expose deployment nginx --port=80 --target-port=8000

Expose a resource as a new Kubernetes service.

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.

Possible resources include (case insensitive):

pod (po), service (svc), replicationcontroller (rc), deployment (deploy), replicaset (rs)

### Usage

`$ expose (-f FILENAME | TYPE NAME) [--port=port] [--protocol=TCP|UDP] [--target-port=number-or-name] [--name=name] [--external-ip=external-ip-of-service] [--type=type]`

# APP MANAGEMENT

This section contains commands for creating, updating, deleting, and viewing your workloads in a Kubernetes cluster.

# annotate

> Update pod 'foo' with the annotation 'description' and the value 'my frontend'. # If the same annotation is set multiple times, only the last value will be applied

    kubectl annotate pods foo description='my frontend'

> Update a pod identified by type and name in "pod.json"

    kubectl annotate -f pod.json description='my frontend'

> Update pod 'foo' with the annotation 'description' and the value 'my frontend running nginx', overwriting any existing value.

    kubectl annotate --overwrite pods foo description='my frontend running nginx'

> Update all pods in the namespace

    kubectl annotate pods --all description='my frontend running nginx'

> Update pod 'foo' only if the resource is unchanged from version 1.

    kubectl annotate pods foo description='my frontend running nginx' --resource-version=1

> Update pod 'foo' by removing an annotation named 'description' if it exists. # Does not require the --overwrite flag.

    kubectl annotate pods foo description-

Update the annotations on one or more resources

All Kubernetes objects support the ability to store additional data with the object as annotations. Annotations are key/value pairs that can be larger than labels and include arbitrary string values such as structured JSON. Tools and system extensions may use annotations to store their own data.

Attempting to set an annotation that already exists will fail unless --overwrite is set. If --resource-version is specified and does not match the current resource version on the server the command will fail.

Valid resource types include:

- all
- certificatesigningrequests (aka 'csr')
- clusterrolebindings
- clusterroles
- componentstatuses (aka 'cs')
- configmaps (aka 'cm')
- controllerrevisions
- cronjobs

# autoscale

> Auto scale a deployment "foo", with the number of pods between 2 and 10, no target CPU utilization specified so a default autoscaling policy will be used:

    kubectl autoscale deployment foo --min=2 --max=10

> Auto scale a replication controller "foo", with the number of pods between 1 and 5, target CPU utilization at 80%:

    kubectl autoscale rc foo --max=5 --cpu-percent=80

Creates an autoscaler that automatically chooses and sets the number of pods that run in a kubernetes cluster.

Looks up a Deployment, ReplicaSet, or ReplicationController by name and creates an autoscaler that uses the given resource as a reference. An autoscaler can automatically increase or decrease number of pods deployed within the system as needed.

### Usage

`$ autoscale (-f FILENAME | TYPE NAME | TYPE/NAME) [--min=MINPODS] --max=MAXPODS [--cpu-percent=CPU]`

### Flags

Create a configmap based on a file, directory, or specified literal value.

A single configmap may package one or more key/value pairs.

When creating a configmap based on a file, the key will default to the basename of the file, and the value will default to the file content. If the basename is an invalid key, you may specify an alternate key.

When creating a configmap based on a directory, each file whose basename is a valid key in the directory will be packaged into the configmap. Any directory entries except regular files are ignored (e.g. subdirectories, symlinks, devices, pipes, etc).

## secret

Create a secret using specified subcommand.

### Usage

`$ secret`

## secret docker-registry

> If you don't already have a .dockercfg file, you can create a dockercfg secret directly by using:

    kubectl create secret docker-registry my-secret --docker-server=DOCKER_REGISTRY_SERVER --docker-username=DOCKER_USER --docker-password=DOCKER_PASSWORD --docker-email=DOCKER_EMAIL

Create a new secret for use with Docker registries.

Dockercfg secrets are used to authenticate against Docker registries.

When using the Docker command line to push images, you can authenticate to a given registry by running: '$ docker login DOCKER REGISTRY SERVER --username=DOCKER USER --password=DOCKER PASSWORD --email=DOCKER _EMAIL'.

That produces a ~/.dockercfg file that is used by subsequent 'docker push' and 'docker pull' commands to

authenticate to the registry. The email address is optional.

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.

### Usage

`$ docker-registry NAME --docker-username=user --docker-password=password --docker-email=email [--docker-server=string] [--from-literal=key1=value1] [--dry-run]`

> Create a new secret named my-secret from an env file

    kubectl create secret generic my-secret --from-env-file=path/to/bar.env

Create a secret based on a file, directory, or specified literal value.

A single secret may package one or more key/value pairs.

When creating a secret based on a file, the key will default to the basename of the file, and the value will default to the file content. If the basename is an invalid key or you wish to chose your own, you may specify an alternate key.

When creating a secret based on a directory, each file whose basename is a valid key in the directory will be packaged into the secret. Any directory entries except regular files are ignored (e.g. subdirectories, symlinks, devices, pipes, etc).

# delete

> Delete a pod using the type and name specified in pod.json.

    kubectl delete -f ./pod.json

> Delete a pod based on the type and name in the JSON passed into stdin.

    cat pod.json | kubectl delete -f -

> Delete pods and services with same names "baz" and "foo"

    kubectl delete pod,service baz foo

> Delete pods and services with label name=myLabel.

    kubectl delete pods,services -l name=myLabel

> Delete a pod with minimal delay

    kubectl delete pod foo --now

> Force delete a pod on a dead node

    kubectl delete pod foo --grace-period=0 --force

> Delete all pods

    kubectl delete pods --all

Delete resources by filenames, stdin, resources and names, or by resources and label selector.

JSON and YAML formats are accepted. Only one type of the arguments may be specified: filenames, resources and names, or resources and label selector.

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.

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.

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.

### Usage

`$ delete ([-f FILENAME] | TYPE [(NAME | -l label | --all)])`

### Flags

Name | Shorthand | Default | Usage
--- | --- | --- | ---
all |  | false | Delete all resources, including uninitialized ones, in the namespace of the specified resource types.
cascade |  | true | If true, cascade the deletion of the resources managed by this resource (e.g. Pods created by a ReplicationController). Default true.
filename | f | [] | Filename, directory, or URL to files containing the resource to delete.
force |  | false | Immediate deletion of some resources may result in inconsistency or data loss and requires confirmation.
grace-period |  | -1 | Period of time in seconds given to the resource to terminate gracefully. Ignored if negative.
ignore-not-found |  | false | Treat "resource not found" as a successful delete. Defaults to "true" when --all is specified.
include-extended-apis |  | true | If true, include definitions of new APIs via calls to the API server. [default true]
include-uninitialized |  | false | If true, the kubectl command applies to uninitialized objects. If explicitly set to false, this flag overrides other flags that make the kubectl commands apply to uninitialized objects, e.g., "--all". Objects with empty metadata.initializers are regarded as initialized.
now |  | false | If true, resources are signaled for immediate shutdown (same as --grace-period=1).
output | o |  | Output mode. Use "-o name" for shorter output (resource/name).
recursive | R | false | Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
selector | l |  | Selector (label query) to filter on, not including uninitialized ones.
timeout |  | 0s | The length of time to wait before giving up on a delete, zero means determine a timeout from the size of the object

# edit

> Edit the service named 'docker-registry':

    kubectl edit svc/docker-registry

> Use an alternative editor

    KUBE_EDITOR="nano" kubectl edit svc/docker-registry

> Edit the job 'myjob' in JSON using the v1 API format:

    kubectl edit job.v1.batch/myjob -o json

> Edit the deployment 'mydeployment' in YAML and save the modified config in its annotation:

    kubectl edit deployment/mydeployment -o yaml --save-config

Edit a resource from the default editor.

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.

Editing is done with the API version used to fetch the resource. To edit using a specific API version, fully-qualify the resource, version, and group.

The default format is YAML. To edit in JSON, specify "-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.

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.

### Usage

`$ edit (RESOURCE/NAME | -f FILENAME)`

### Flags

--- | --- | --- | ---
filename | f | [] | Filename, directory, or URL to files to use to edit the resource
include-extended-apis |  | true | If true, include definitions of new APIs via calls to the API server. [default true]
include-uninitialized |  | false | If true, the kubectl command applies to uninitialized objects. If explicitly set to false, this flag overrides other flags that make the kubectl commands apply to uninitialized objects, e.g., "--all". Objects with empty metadata.initializers are regarded as initialized.
output | o | yaml | Output format. One of: yaml|json.
output-patch |  | false | Output the patch if the resource is edited.
record |  | false | Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.
recursive | R | false | Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
save-config |  | false | If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future.
validate |  | true | If true, use a schema to validate the input before sending it
windows-line-endings |  | false | Defaults to the line ending native to your platform.

    kubectl get all

Display one or many resources

Prints a table of the most important information about the specified resources. You can filter the list using a label selector and the --selector flag. If the desired resource type is namespaced you will only see results in your current namespace unless you pass --all-namespaces.

Uninitialized objects are not shown unless --include-uninitialized is passed.

By specifying the output as 'template' and providing a Go template as the value of the --template flag, you can filter the attributes of the fetched resources.

    kubectl apply -f ./pod.json

> Apply the JSON passed into stdin to a pod.

    cat pod.json | kubectl apply -f -

> Note: --prune is still in Alpha # Apply the configuration in manifest.yaml that matches label app=nginx and delete all the other resources that are not in the file and match label app=nginx.

    kubectl apply --prune -f manifest.yaml -l app=nginx

> Apply the configuration in manifest.yaml and delete all the other configmaps that are not in the file.

    kubectl apply --prune -f manifest.yaml --all --prune-whitelist=core/v1/ConfigMap

Apply a configuration to a resource by filename or stdin. The resource name must be specified. This resource will be created if it doesn't exist yet. To use 'apply', always create the resource initially with either 'apply' or 'create --save-config'.

JSON and YAML formats are accepted.

Alpha Disclaimer: the --prune functionality is not yet complete. Do not use unless you are aware of what the current state is. See https://issues.k8s.io/34274.

## edit-last-applied

> Edit the last-applied-configuration annotations by type/name in YAML.

    kubectl apply edit-last-applied deployment/nginx

> Edit the last-applied-configuration annotations by file in JSON.

    kubectl apply edit-last-applied -f deploy.yaml -o json

Edit the latest last-applied-configuration annotations of resources from the default editor.

The edit-last-applied 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.

The default format is YAML. To edit in JSON, specify "-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.

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.

### Usage

`$ edit-last-applied (RESOURCE/NAME | -f FILENAME)`

output | o | yaml | Output format. One of: yaml|json.
record |  | false | Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.
recursive | R | false | Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
windows-line-endings |  | false | Defaults to the line ending native to your platform.

## set-last-applied

    kubectl apply set-last-applied -f path/

> Set the last-applied-configuration of a resource to match the contents of a file, will create the annotation if it does not already exist.

    kubectl apply set-last-applied -f deploy.yaml --create-annotation=true

Set the latest last-applied-configuration annotations by setting it to match the contents of a file. This results in the last-applied-configuration being updated as though 'kubectl apply -f <file>' was run, without updating any other parts of the object.

# proxy

> To proxy all of the kubernetes api and nothing else, use:

    $ kubectl proxy --api-prefix=/

> To proxy only part of the kubernetes api and also some static files:

    $ kubectl proxy --www=/my/files --www-prefix=/static/ --api-prefix=/api/

> The above lets you 'curl localhost:8001/api/v1/pods'. # To proxy the entire kubernetes api at a different root, use:

    $ kubectl proxy --api-prefix=/custom/

> The above lets you 'curl localhost:8001/custom/api/v1/pods' # Run a proxy to kubernetes apiserver on port 8011, serving static content from ./local/www/

    kubectl proxy --port=8011 --www=./local/www/

> Run a proxy to kubernetes apiserver on an arbitrary local port. # The chosen port for the server will be output to stdout.

    kubectl proxy --port=0

### Usage

`$ api-versions`

# certificate

Modify certificate resources.

### Usage

`$ certificate SUBCOMMAND`

## approve

Approve a certificate signing request.

kubectl certificate approve allows a cluster admin to approve a certificate signing request (CSR). This action tells a certificate signing controller to issue a certificate to the requestor with the attributes requested in the CSR.

SECURITY NOTICE: Depending on the requested attributes, the issued certificate can potentially grant a requester access to cluster resources or to authenticate as a requested identity. Before approving a CSR, ensure you understand what the signed certificate can do.

### Usage

    kubectl cluster-info dump --all-namespaces

> Dump a set of namespaces to /path/to/cluster-state

    kubectl cluster-info dump --namespaces default,kube-system --output-directory=/path/to/cluster-state

Dumps cluster info out suitable for debugging and diagnosing cluster problems. By default, dumps everything to stdout. You can optionally specify a directory with --output-directory. If you specify a directory, kubernetes will build a set of files in that directory. By default only dumps things in the 'kube-system' namespace, but you can switch to a different namespace with the --namespaces flag, or specify --all-namespaces to dump all namespaces.

The command also dumps the logs of all of the pods in the cluster, these logs are dumped into different directories based on namespace and pod name.

### Usage

# drain

> Drain node "foo", even if there are pods not managed by a ReplicationController, ReplicaSet, Job, DaemonSet or StatefulSet on it.

    $ kubectl drain foo --force

> As above, but abort if there are pods not managed by a ReplicationController, ReplicaSet, Job, DaemonSet or StatefulSet, and use a grace period of 15 minutes.

    $ kubectl drain foo --grace-period=900

Drain node in preparation for maintenance.

The given node will be marked unschedulable to prevent new pods from arriving. 'drain' evicts the pods if the APIServer supports eviction (http://kubernetes.io/docs/admin/disruptions/). 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. --force will also allow deletion to proceed if the managing resource of one or more pods is missing.

'drain' waits for graceful termination. You should not operate on the machine until the command completes.

When you are ready to put the node back into service, use kubectl uncordon, which will make the node schedulable again.

# config

Modify kubeconfig files using subcommands like "kubectl config set current-context my-context"

The loading order follows these rules:

1. If the --kubeconfig flag is set, then only that file is loaded. The flag may only be set once and no merging takes place.
2. If $KUBECONFIG environment variable is set, then it is used a list of paths (normal path delimitting rules for your system). These paths are merged. When a value is modified, it is modified in the file that defines the stanza. When a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the last file in the list.
3. Otherwise, ${HOME}/.kube/config is used and no merging takes place.

minify |  | false | Remove all information not used by current-context from the output
no-headers |  | false | When using the default or custom-column output format, don't print headers (default print headers).
output | o |  | Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
output-version |  |  | DEPRECATED: To use a specific API version, fully-qualify the resource, version, and group (for example: 'jobs.v1.batch/myjob').
raw |  | false | Display raw byte data
show-all | a | true | When printing, show all resources (default show all pods including terminated one.)
show-labels |  | false | When printing, show all labels as the last column (default hide labels column)
sort-by |  |  | If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
template |  |  | Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].

# explain

> Get the documentation of the resource and its fields

    kubectl explain pods

> Get the documentation of a specific field of a resource

    kubectl explain pods.spec.containers

List the fields for supported resources

This command describes the fields associated with each supported API resource. Fields are identified via a simple JSONPath identifier:

<type>.<fieldName>[.<fieldName>]

Add the --recursive flag to display all of the fields at once without descriptions. Information about each field is retrieved from the server in OpenAPI format.

Valid resource types include:

- all
- certificatesigningrequests (aka 'csr')
- clusterrolebindings
- clusterroles
- componentstatuses (aka 'cs')
- configmaps (aka 'cm')
- controllerrevisions
- cronjobs
- customresourcedefinition (aka 'crd')
- daemonsets (aka 'ds')
- deployments (aka 'deploy')
- endpoints (aka 'ep')
- events (aka 'ev')
- horizontalpodautoscalers (aka 'hpa')
- ingresses (aka 'ing')
- jobs
- limitranges (aka 'limits')
- namespaces (aka 'ns')
- networkpolicies (aka 'netpol')
- nodes (aka 'no')
- persistentvolumeclaims (aka 'pvc')
- persistentvolumes (aka 'pv')
- poddisruptionbudgets (aka 'pdb')
- podpreset
- pods (aka 'po')
- podsecuritypolicies (aka 'psp')
- podtemplates
- replicasets (aka 'rs')
- replicationcontrollers (aka 'rc')
- resourcequotas (aka 'quota')
- rolebindings
- roles
- secrets
- serviceaccounts (aka 'sa')
- services (aka 'svc')
- statefulsets (aka 'sts')
- storageclasses (aka 'sc')
