Design of CF

Every App deployed to CF is a member of Org and Space

Owner -> Org -> Space -> App

Every Space — contains Apps and Services

Control Policy — Access control list at Space and Members level

You can restrict access to any Space for Team members

For User Apps

App name — URL — status — Num of Instances — RAM — Disk — CPU

For 3rd party services — System services

System services are Databases, Queues, Caches, etc

App name — Service name—Plan — Bound Apps

Apps are Bound to Services.

List of CF commands:

  1. cf target [shows — current Username, Org and Space ]
  2. cf push **.jar appname [ Artifact name(jar/war) and unique App name — deploy the jar to Cloud and run the Application]
