# 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 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).

> 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

    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.

- An annotation is a key/value pair that can hold larger (compared to a label), and possibly not human-readable, data.
- It is intended to store non-identifying auxiliary data, especially data manipulated by tools and system extensions.
- If --overwrite is true, then existing annotations can be overwritten, otherwise attempting to overwrite an annotation will result in an error.
- If --resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used.

Valid resource types include:

- clusters (valid only for federation apiservers)
- componentstatuses (aka 'cs')
- configmaps (aka 'cm')
- 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')

> Create a new configmap named my-config with key1=config1 and key2=config2

    kubectl create configmap my-config --from-literal=key1=config1 --from-literal=key2=config2

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).

### Usage

## 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.

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]`

    kubectl create secret generic my-secret --from-file=ssh-privatekey=~/.ssh/id_rsa --from-file=ssh-publickey=~/.ssh/id_rsa.pub

> Create a new secret named my-secret with key1=supersecret and key2=topsecret

    kubectl create secret generic my-secret --from-literal=key1=supersecret --from-literal=key2=topsecret

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, 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 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 | [-all] to select all the specified resources.
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]
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.
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 service 'docker-registry' in JSON using the v1 API format:

    kubectl edit svc/docker-registry --output-version=v1 -o json

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.

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.

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

Name | Shorthand | Default | Usage
--- | --- | --- | ---

include-extended-apis |  | true | If true, include definitions of new APIs via calls to the API server. [default true]
output | o | yaml | Output format. One of: yaml|json.
output-version |  |  | Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
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. This is useful when you want to perform kubectl apply on this object in the future.
schema-cache-dir |  | ~/.kube/schema | If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema'
validate |  | true | If true, use a schema to validate the input before sending it

Display one or many resources.

Valid resource types include:

- clusters (valid only for federation apiservers)
- componentstatuses (aka 'cs')
- configmaps (aka 'cm')
- 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
- nodes (aka 'no')
- persistentvolumeclaims (aka 'pvc')
- persistentvolumes (aka 'pv')
- pods (aka 'po')
- podsecuritypolicies (aka 'psp')

- thirdpartyresources

This command will hide resources that have completed. For instance, pods that are in the Succeeded or Failed phases. You can see the full results for any resource by providing the '--show-all' flag.

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 resource(s).

# api-versions

### Usage

`$ api-versions`

# certificate

### 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

`$ approve (-f FILENAME | NAME)`

### Flags

Name | Shorthand | Default | Usage
--- | --- | --- | ---
filename | f | [] | Filename, directory, or URL to files identifying the resource to update
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.

## deny

Deny a certificate signing request.

kubectl certificate deny allows a cluster admin to deny a certificate signing request (CSR). This action tells a certificate signing controller to not to issue a certificate to the requestor.

### Usage

`$ deny (-f FILENAME | NAME)`

### Flags

Name | Shorthand | Default | Usage
--- | --- | --- | ---
filename | f | [] | Filename, directory, or URL to files identifying the resource to update

    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

`$ dump`

### Flags

Name | Shorthand | Default | Usage
--- | --- | --- | ---
all-namespaces |  | false | If true, dump all namespaces. If true, --namespaces is ignored.

### Usage

`$ cordon NODE`

# 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 eviciton (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.

'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.

# taint

> Update node 'foo' with a taint with key 'dedicated' and value 'special-user' and effect 'NoSchedule'. # If a taint with that key and effect already exists, its value is replaced as specified.

    kubectl taint nodes foo dedicated=special-user:NoSchedule

> Remove from node 'foo' the taint with key 'dedicated' and effect 'NoSchedule' if one exists.

    kubectl taint nodes foo dedicated:NoSchedule-

> Remove from node 'foo' all the taints with key 'dedicated'

    kubectl taint nodes foo dedicated-

Update the taints on one or more nodes.

- A taint consists of a key, value, and effect. As an argument here, it is expressed as key=value:effect.
- The key must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 253 characters.
- The value must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 253 characters.
- The effect must be NoSchedule or PreferNoSchedule.
- Currently taint can only apply to node.

### Usage

`$ taint NODE NAME KEY_1=VAL_1:TAINT_EFFECT_1 ... KEY_N=VAL_N:TAINT_EFFECT_N`

# uncordon

> Mark node "foo" as schedulable.

    $ kubectl uncordon foo

Mark node as schedulable.

### Usage

`$ uncordon NODE`

# KUBECTL SETTINGS AND USAGE

# completion

Output shell completion code for the given shell (bash or zsh).

This command prints shell code which must be evaluation to provide interactive completion of kubectl commands.

$ source <(kubectl completion bash)

will load the kubectl completion code for bash. Note that this depends on the bash-completion framework. It must be sourced before sourcing the kubectl completion, e.g. on the Mac:

$ brew install bash-completion $ source $(brew --prefix)/etc/bash_completion $ source <(kubectl completion bash)

If you use zsh [1], the following will load kubectl zsh completion:

$ source <(kubectl completion zsh)

[1] zsh completions are only supported in versions of zsh >= 5.2

### Usage

`$ completion SHELL`

# 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.

### Usage

`$ config SUBCOMMAND`
