Architecture
Within a PCF foundation, a “mirror service” makes a full mirror of each Git repository (“R1”, “R2”, “R3”) used by a Config Server service instance. The Config Server service instance, in turn, clones repositories from this mirror rather than cloning from the external Git server directly.

CLI
1. Before getting started:
cf config // Write default values to the config
cf config [--async-timeout TIMEOUT_IN_MINUTES] [--trace (true | false | path/to/file)] [--color (true | false)] [--locale (LOCALE | CLEAR)]
#OPTIONS:
# --async-timeout Timeout for async HTTP requests
# --color Enable or disable color
# --locale Set default locale. If LOCALE is 'CLEAR', previous locale is deleted.
# --trace Trace HTTP requests
cf login,l [-a API_URL] [-u USERNAME] [-p PASSWORD] [-o ORG] [-s SPACE] [--sso | --sso-passcode PASSCODE] [--origin ORIGIN]
cf target,t [-o ORG] [-s SPACE] # Set or view the targeted org or space
cf logout,lo
2. Application lifecycle:
cf apps,a # List all apps in the target space
cf push,p
# Push a new app or sync changes to an existing app
# -b 自定义的buildpack地址，一般如github上打包的.tar.gz的文件包
# -c 指定启动命令，如nodejs中，cf push -c node myappstart.js，指定使用node myappstart.js来启动你的应用
# -d 指定域名，如example.com
# -f 指定manifest.yml文件路径，无此参数时，cf push会将当前你所处文件目录遍历，并上传到pivotal中你申请的空间中，并使用当前目录中manifest.yml文件配置的选项启动应用，如果没有此文件，一般会报错，关于manifest.yml的用法，请参考下面实例部分；
# -p 指定你要上传发布的应用源码路径；默认是当前路径
# -m 指定分配给该应用的内在大小如:cf push -m 10mb
# -h 指定主机
cf start,st app_name # Start an app
cf stop,sp app_name # stop an app
cf restart,rs app_name # Stop all instances of the app, then start them again. This causes downtime.
cf restage,rg #Recreate the app's executable artifact using the latest pushed app files and the latest environment (variables, service bindings, buildpack, stack, etc.). This action will cause app downtime.
cf delete,d app_name [-f,-r]
# -f Force deletion without confirmation
# -r Also delete any mapped routes
cf run-task,rt cf app_name COMMAND [-k DISK] [-m MEMORY] [--name TASK_NAME] # Run a one-off task on an app
cf logs app_name --recent # Tail or show recent logs for an app
cf ssh app_name # SSH to an application container instance
cf app app_name --guid # Display health and status for an app
cf env,e app_name # Show all env variables for an app
cf scale app_name# Change or view the instance count, disk space limit, and memory limit for an app
cf events app_name # Show recent app events
cf set-env,se app_name ENV_VAR_NAME ENV_VAR_VALUE #Set an env variable for an app
cf create-app-manifest app_name [-p /path/to/<app-name>_manifest.yml] #Create an app manifest for an app that has been pushed successfully
