In order to start working on a Kubernetes cluster, it is necessary to install the Kubernetes command line (*kubectl*). Follow these steps to install the *kubectl* CLI:
* Execute the following commands to install the *kubectl* CLI. OS_DISTRIBUTION is a placeholder for the binary distribution of *kubectl*, remember to replace it with the corresponding distribution for your Operating System (OS).
$ curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/OS_DISTRIBUTION/amd64/kubectl
$ chmod +x ./kubectl
$ sudo mv ./kubectl /usr/local/bin/kubectl
> TIP: Once the *kubectl* CLI is installed, you can obtain information about the current version with the *kubectl version* command.
----
> NOTE: You can also install *kubectl* by using the *sudo apt-get install kubectl* command.
* Check that *kubectl* is correctly installed and configured by running the *kubectl cluster-info* command:
$ kubectl cluster-info
> NOTE: The *kubectl cluster-info* command shows the IP addresses of the Kubernetes node master and its services.

* You can also verify the cluster by checking the nodes. Use the following command to list the connected nodes:
$ kubectl get nodes
<% if current.id == 'get-started-kubernetes' %>
<%= documentation_img '/images/img/platforms/kubernetes/k8-tutorial-32-single.png', 'Check cluster node' %>
<% else %>
<%= documentation_img '/images/img/platforms/kubernetes/k8-tutorial-32-multi.png', 'Check cluster node' %>
<% end %>
* To get complete information on each node, run the following:
$ kubectl describe node
<%= documentation_img '/images/img/platforms/kubernetes/k8-tutorial-33.png', 'Check Kubernetes node info' %>
