# 扩容 Deployment

使用 **kubectl scale** 动态调整 Pod 的副本数，比如将将 Pod 的数量增加到 5 个：

```properties
$ kubectl scale deploy nginx-deploy --replicas=5
deployment.apps/nginx-deploy scaled
```

```properties
$ kubectl get deploy 
NAME           READY   UP-TO-DATE   AVAILABLE   AGE
nginx-deploy   5/5     5            5           74m
```
