## kubectl
The ```kubectl``` command provides command line access to the kubernetes API.

### Commands

#### version
Print the version of the client and server.

Usage: 
```
  kubectl version [flags]

 Available Flags:
      --api-version="v1beta1": The version of the API to use against the server

JSON and YAML formats are accepted.

If both a filename and command line arguments are passed, the command line
arguments are used and the filename is ignored.

submits an update to a resource right when you submit a delete, their update
will be lost along with the rest of the resource.

```sh
  $ kubectl delete -f pod.json
  <delete a pod using the type and id pod.json>

* [ReplicationController Commands](#replication-controller-commands)
* [RESTful Commands](#restful-commands)
* [Complete Details](#details)
  * [Usage](#usage)
  * [Options](#options)

### Replication Controller Commands

#### Run
```
kubecfg [options] run <image> <replicas> <controller-name>
```

Creates a Kubernetes ReplicaController object.

* `[options]` are described in the [Options](#options) section.
* `<image>` is the Docker image to use.
* `<replicas>` is the number of replicas of the container to create.
* `<controller-name>` is the name to assign to this new ReplicaController.

##### Example

```
kubecfg -p 8080:80 run dockerfile/nginx 2 myNginxController
```

#### Resize
```
kubecfg [options] resize <controller-name> <new-size>
```

Changes the desired number of replicas, causing replicas to be created or deleted.

* `[options]` are described in the [Options](#options) section.


##### Example
```
kubecfg resize myNginxController 3
```

#### Stop
```
kubecfg [options] stop <controller-name>
```

Stops a controller by setting its desired size to zero. Syntactic sugar on top of resize.

* `[options]` are described in the [Options](#options) section.

#### Remove
```
kubecfg [options] rm <controller-name>
```

Delete a replication controller. The desired size of the controller must be zero, by
calling either `kubecfg resize <controller-name> 0` or `kubecfg stop <controller-name>`.

* `[options]` are described in the [Options](#options) section.

### RESTful Commands
Kubecfg also supports raw access to the basic restful requests. There are four different resources you can acccess:

   * `pods`
   * `replicationControllers`
   * `services`
   * `minions`

###### Common Flags

   * -yaml : output in YAML format
   * -json : output in JSON format
   * -c <config-file> : Accept a file in JSON or YAML for POST/PUT
   
#### Commands

##### get
Raw access to a RESTful GET request.

```
kubecfg [options] get pods/pod-abc-123
```

##### list
Raw access to a RESTful LIST request.

```
kubecfg [options] list pods
```

##### create
Raw access to a RESTful POST request.

```
kubecfg <-c some/body.[json|yaml]> [options] create pods
```

##### update
Raw access to a RESTful PUT request.

```
kubecfg <-c some/body.[json|yaml]> [options] update pods/pod-abc-123
```

##### delete
Raw access to a RESTful DELETE request.

```
kubecfg [options] delete pods/pod-abc-123
```


### Details

#### Usage
```
kubecfg -h [-c config/file.json] [-p :,..., :] <method>
