60.1 Cloud Foundry

如果不指定其他打包方式，Cloud Foundry会启用它提供的默认打包方式。Cloud Foundry的Java buildpack对Spring应用有出色的支持，包括Spring Boot。你可以部署独立的可执行jar应用，也可以部署传统的.war形式的应用。

一旦你构建应用（比如，使用mvn clean package）并安装cf命令行工具，你可以使用下面的cf push命令（将路径指向你编译后的.jar）来部署应用。在发布应用前，确保你已登陆cf命令行客户端。下面的代码行展示了如何使用cf push命令来部署应用程序：

$ cf push acloudyspringtime -p target/demo-0.0.1-SNAPSHOT.jar

注 在前面的例子中，我们将acloudyspringtime替换为你为应用程序指定的cf值。

查看cf push文档获取更多可选项。如果相同目录下存在manifest.yml，Cloud Foundry会使用它。

就此，cf将开始上传你的应用，生成如下图所示的输出：

App started

恭喜！应用现在处于运行状态！

应用程序启动后，可以使用cf apps命令验证部署的应用程序的状态，如下例所示：

$ cf apps
Getting applications in ...
OK

name                 requested state   instances   memory   disk   urls

acloudyspringtime    started           1/1         512M     1G     acloudyspringtime.cfapps.io
...

一旦Cloud Foundry意识到你的应用已经部署，你就可以点击给定的应用URI。在前面的示例中，你可以通过http://acloudyspringtime.cfapps.io/找到它。
