您必须拥有一个 Kubernetes 集群，并且必须使用 kubectl 命令行工具与你的集群进行通信。如果您还没有一个集群，您可以通过 [Minikube](/docs/getting-started-guides/minikube) 创建一个集群，或者使用这些 Kubernetes playground ：

* [Play with Kubernetes](http://labs.play-with-k8s.com/)

You need to have a Kubernetes cluster, and the kubectl command-line tool must
be configured to communicate with your cluster. If you do not already have a
cluster, you can create one by using
[Minikube](/docs/getting-started-guides/minikube),
or you can use one of these Kubernetes playgrounds:
