# cf login -a https://api.run.pivotal.io
上传并运行APP
在程序根目录下运行这个命令后，cf就会把当前目录包括源代码的所有文件，打包并上传到CF上面，之后CF就会自动分析出APP的语言，根据源代码下载所需的依赖，编译程序并将其重新打包成一个“露珠”(dropplet，可以反复运行并延展的独立程序包)。这一切都是后台自动完成的，无需任何设置。这时候在你设置网段的任何人便可以去浏览我们的APP了。
开发员可以定义APP的名称(name)，运行实例的数量(number of instances)，内存(Memory Limit)，子域名(subdomain)，域名(domain)，还有可选择绑定的服务(services，会在另一篇文章深入介绍)，等等。
# cf push APP
监控和调试APP
显示已经上传的APP以及它们的运行状态。
# cf apps
显示我们上传APP的log，包括env.log, staging_task.log, stderr.log, 和stdout.log。我们的log一般会在stderr或stdout找到，另外两个为系统log。
如果去掉'--recent'，cf则会对log进行'tail -f'的功能。
# cf logs APP --recent
显示我们上传APP的根目录文件夹结构，一般会反应我们在本地上传的目录结构。我们还可以运用这个命令查看已上传文件的内容。
# cf files APP
