Bluemix实战教程： CF命令学习分享

为了偷懒从接触bluemix到现在，应用程序的部署设置等操作一直到在bluemix平台上直接可视化操作的。作为一个开发爱好者当让使用命令来操作会更帅呦。今天终于学习了下CF的命令操作，下面将我学习中的一点体会和大家分享一下。

安装

命令行工具的安装也很简便，直接从GitHub上下载即可（https://github.com/cloudfoundry/cli/releases）。

首先，使用"cf api"建立于 Bluemix 的连接，连接地址是 https://api.ng.bluemix.net
连接 Bluemix

USAGE:
cf api [URL]

C:\Users\IBM_ADMIN>cf api https://api.ng.bluemix.net Setting api endpoint to https://api.ng.bluemix.net... OK

API endpoint: https://api.ng.bluemix.net (API version: 2.2.0)
Not logged in. Use 'cf login' to log in.

其次，运行"cf login"登录到 Bluemix 并选择所要工作的组织和空间

登录 Bluemix

USAGE:
cf login [-a API_URL] [-u USERNAME] [-p PASSWORD] [-o ORG] [-s SPACE]

C:\Users\IBM_ADMIN>cf login
API endpoint: https://api.ng.bluemix.net 
Username> shyou@qq.com

Password>
Authenticating...
OK

Select an org (or press enter to skip):
1. shyou@qq.com
2. OE_Runtimes_SVT

Org> 1
Targeted org shyou@qq.com

Targeted space dev

API endpoint: https://api.ng.bluemix.net (API version: 2.2.0)
User: shyou@qq.com
Org: shyou@qq.com
Space: dev

部署应用到 Bluemix

运行"cf push"命令来部署应用到 Bluemix：

USAGE:
Push a single app (with or without a manifest):
cf push APP [-b BUILDPACK_NAME] [-c COMMAND] [-d DOMAIN] [-f MANIFEST_PATH]
[-i NUM_INSTANCES] [-m MEMORY] [-n HOST] [-p PATH] [-s STACK] [-t TIMEOUT]
[--no-hostname] [--no-manifest] [--no-route] [--no-start]

C:\Users\IBM_ADMIN>cf push HelloBluemix -p C:\A_Workspace\apps\HelloWithMongo.war
Creating app HelloBluemix in org shyou@qq.com / space dev as shyou@qq.com...
OK

Using route HelloBluemix.ng.bluemix.net

OK

部署成功以后可以运行"cf apps"查看应用的运行状态。在这里有几点需要说明：第一，<app_name>最好要做到唯一，不和部署在 Bluemix 上的其他应用重复，因为默认情况下这个<app_name>会和 domain 组成应用的访问连接，即：<app_name>.ng.bluemix.net，每一个应用的访问连接应该是唯一的，如果不是唯一，部署的过程中会报错提醒，我们只要换一个不一样的名字即可；第二，cf push 命令默认会将当前目录下的所有内容 push 到云端，除非我们显示的使用 –p 参数显示的指定要部署的内容；第三，从上面的输出中可以看到，应用的访问路径是"urls:
HelloBluemix.ng.bluemix.net"，即"http:// HelloBluemix.ng.bluemix.net"，这也是默认的 Bluemix 中应用的访问路径的统一格"appname.domain"。
