To interact with Kubernetes during this bootcamp we’ll use the command line interface, kubectl. We’ll explain kubectl in detail in the next modules, but for now, we’re just going to look at some cluster information. To check if kubectl is installed you can run the kubectl version command:

kubectl version

OK, kubectl is configured and we can see both the client and the server Kubernetes version: 1.5. The client version is the kubectl version; the server version is the Kubernetes version installed on the master. Here, you can also see details about the build.

Let’s view the cluster details. We’ll do that by running kubectl cluster-info:

kubectl cluster-info

We have a running master and a dashboard. The Kubernetes dashboard allows you to view your applications in a UI. During this tutorial, we’ll be focusing on the command line for deploying and exploring our application. To view the nodes in the cluster, run the kubectl get nodes command:

kubectl get nodes

This command shows all nodes that can be used to host our applications. Now we have only one node, and we can see that it’s status is ready (it is ready to accept applications for deployment).
