<!-- <p>Scaling out a Deployment will ensure new Pods are created and scheduled to Nodes with available resources. Scaling in will reduce the number of Pods to the new desired state. Kubernetes also supports
|

<p>扩展 Deployment 将创建新的 Pods，并将资源调度请求分配到有可用资源的节点上，收缩 会将 Pods 数量减少至所需的状态。Kubernetes 还支持 Pods 的<a href="http://kubernetes.io/docs/user-guide/horizontal-pod-autoscaling/">自动缩放</a>，但这并不在本教程的讨论范围内。将 Pods 数量收缩到0也是可以的，但这会终止 Deployment 上所有已经部署的 Pods。</p>
