To deploy and manage applications on Kubernetes, you’ll use the Kubernetes command-line tool, [kubectl](/docs/user-guide/kubectl/kubectl/). It lets you inspect your cluster resources, create, delete, and update components, and much more. You will use it to look at your new cluster and bring up example apps.
|
||
|
||
## Installing kubectl
|
||
|
||
If you downloaded a pre-compiled [release](https://github.com/kubernetes/kubernetes/releases), kubectl should be under `platforms/<os>/<arch>` from the tar bundle.
|
||
|
||
If you built from source, kubectl should be either under `_output/local/bin/<os>/<arch>` or `_output/dockerized/bin/<os>/<arch>`.
|
||
|
||
The kubectl binary doesn't have to be installed to be executable, but the rest of the walkthrough will assume that it's in your PATH.
|
||
|
||
The simplest way to install is to copy or move kubectl into a dir already in PATH (e.g. `/usr/local/bin`). For example:
|
||
|
||
```shell
|
||
# OS X
|
||
$ sudo cp kubernetes/platforms/darwin/amd64/kubectl /usr/local/bin/kubectl
|
||
# Linux
|
||
$ sudo cp kubernetes/platforms/linux/amd64/kubectl /usr/local/bin/kubectl
|
||
```
|
||
|
||
You also need to ensure it's executable:
|
||
|
||
```shell
|
||
$ sudo chmod +x /usr/local/bin/kubectl
|
||
```
|
||
|
||
If you prefer not to copy kubectl, you need to ensure the tool is in your path:
|
||
|
||
```shell
|
||
# OS X
|
||
export PATH=<path/to/kubernetes-directory>/platforms/darwin/amd64:$PATH
|
||
|
||
# Linux
|
||
export PATH=<path/to/kubernetes-directory>/platforms/linux/amd64:$PATH
|
||
```
|
||
|
||
## Configuring kubectl
|
||
|
||
In order for kubectl to find and access the Kubernetes cluster, it needs a [kubeconfig file](/docs/user-guide/kubeconfig-file), which is created automatically when creating a cluster using kube-up.sh (see the [getting started guides](/docs/getting-started-guides/) for more about creating clusters). If you need access to a cluster you didn't create, see the [Sharing Cluster Access document](/docs/user-guide/sharing-clusters).
|
||
By default, kubectl configuration lives at `~/.kube/config`.
|
||
|
||
#### Making sure you're ready
|
||
|
||
Check that kubectl is properly configured by getting the cluster state:
|
||
|
||
```shell
|
||
$ kubectl cluster-info
|
||
```
|
||
|
||
If you see a url response, you are ready to go.
