如何获取app的环境变量？

[Ivar_PredixCN]

PROBLEM
Your app or service uses environment variables at run time (possibly set through a manifest.yml file) to connect apps and services, but the connections seem to not be working properly.

Or, you want to find out:
Client ID

Zone ID

Logging Level

Application ID

Application URI


For example: You might have an app that points to a particular service. This service URL is referenced in the manifest.yml file. However, since you've been trying a few things out, you've pushed several versions of the service and you want to check which service the deployed app is pointing to.



STEPS

cf env NAME_OF_APP_OR_SERVICE

Example result:

Getting env variables for app NAME_OF_APPLICATION_OR_SERVICE in org ORG_NAME / space SPACE_NAME as USER_NAME...
 OK

You can retrieve environment variables for your pushed apps/services, but you will not be able to see logs for the service instances which you depend on such as Time Series, Asset, or UAA.
