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。
一旦你构建了应用(比如,使用mvn clean package
)并安装了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。在发布一个应用前,确保你已登陆cf命令行客户端。
$ cf push acloudyspringtime -p target/demo-0.0.1-SNAPSHOT.jar
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开始上传你的应用:

恭喜!应用现在处于运行状态!
检验部署应用的状态是很简单的:
$ cf apps

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,此处是acloudyspringtime.cfapps.io/。
