下面一些什么时候这种做法有意义的示例：


#### 一个简单的应用程序

如果你的应用程序**足够简单**，你不需要（至少现在不需要）过多地微调进程数量，并且你可以使用自动默认值，那么你可能需要容器中的进程管理器 （使用官方 Docker 镜像），并且你在**单个服务器**而不是集群上运行它。

#### Docker Compose

你可以使用 **Docker Compose** 部署到**单个服务器**（而不是集群），因此你没有一种简单的方法来管理容器的复制（使用 Docker Compose），同时保留共享网络和 **负载均衡**。

然后，你可能希望拥有一个**单个容器**，其中有一个**进程管理器**，在其中启动**多个worker进程**。

#### Prometheus和其他原因

     * If the user did not specify any includes, the given {@code defaultIncludes} are used.
     * These defaults depend on the plugin.
     * For example, the default include of the Java compiler plugin is <code>"**&sol;*.java"</code>.
     *
     * <p>If the user did not specify any excludes, the default is often files generated
     * by Source Code Management (<abbr>SCM</abbr>) software or by the operating system.
