Feature Request: Allow app devs to pass a -s and -o flag to `cf push`

[abbyachau]

Command

• cf push
• but could be extended to any command on an app that changes state (cf restart, cf restage, cf map-route, unmap-route, set-env, start, stop, run-task)

What

Allow for cf push my-app -s my-space -o my-org so that I am always sure that I am targeting the correct environment when I push

Why

• scripts that run (concurrently)
• eliminates human error
