Show all system env variables with "cf env app" #263

Closed cdavisafc closed 9 years ago

cdavisafc commented 10 years ago

Seems that the only system env variable returned from this call is VCAP_SERVICES. I don't see any reason why it shouldn't expose all of them, but the one that I need right now is VCAP_APPLICATION.

We have created an issue in Pivotal Tracker to manage this. You can view the current status of your issue at: https://www.pivotaltracker.com/story/show/78533524.

@cdavisafc CLI Team indicated that all system variables should be returned with 'cf env app-name' Can you verify that you are not seeing VCAP_APPLICATION despite it being set correctly? Thanks

cdavisafc commented 10 years ago

VCAP_APPLICATION is set by the system but is not returned with 'cf env app-name' - you see the same behavior, right?

goehmen commented 10 years ago

@cdavisafc I just talked to the rintime team. You used to be able to use cf files to read the CC's env.log file which included vcap_application however, that file was removed approx 8/19/2014 possibly over concerns that it contained information that required more security. Currently, the only way to view vcap_application is write your app to provide access to it. I asked Dieu/runtime if they wanted to change that and provide an endpoint the CLI can hit to obtain access to the variable but if they do not, there is not much I can do from the CLI side.

I understand the change from the env.log file and why we eliminated it in lieu of the "cf env" command. My question here is why do we treat VCAP_SERVICES differently from VCAP_APPLICATION? They are both system env variables, the former is returned from cf env, the latter is not. Why?

I have a scenario where I need both. When a developer is working locally and using the likes of Spring Cloud Connector (https://github.com/spring-cloud/spring-cloud-connectors) I need to set env variables in my local development environment; Spring Cloud Connector needs both VCAP_SERVICES and VCAP_APPLICATION. I've been teaching people to use "cf files ..." to get those variable values. I can no longer teach them that trick because only one of the values is available with "cf env"

Thanks @cdavisafc

I talked to @dieucao about this and it looks like runtime can get this done pretty easily. I dropped https://www.pivotaltracker.com/story/show/80664762 in the runtime backlog.

When that story is done, the CLI team can extend the functionality to the CLI.

Good?

Cool, thanks @goehmen and @dieucao!
