Support VCAP_SERVICES_FILE_PATH

[sebastien-savalle]

What shall be solved?
Cloud foundry team introduced a new option to load VCAP service bindings from a file. This was done to bypass the variable limit set to 128kb.
So, it would be nice to support this feature in CAP to avoid usage of fallbacks solution like environment variables.

Proposed solution
@sap/xsenv library already support this feature and it would be nice to also support in CAP since version 5.6.0
https://www.npmjs.com/package/@sap/xsenv/v/5.6.1?activeTab=code

You can also find more details here:

Thanks a lot,
Sebastien

Hi @sebastien-savalle ,

This feature should be realized in the @sap/cds module. A request for supporting alternative credentials formats is currently in discussion.

Thanks and best regards,
Heiko

Hi @hm23, I agree, this should be done in @sap/cds but that means the @cap-js/telemetry should no longer read the process.env variables directly. It should rely on cds-env.

Thanks,
Seb

Hi @hm23, any news on this topic ? Could you rely on cds-env and get rid of direct access to process env ?

See:

telemetry/lib/utils.js

Line 107 in ae3e619

const vcap = JSON.parse(process.env.VCAP_SERVICES)

Hi @sebastien-savalle, it's in progress. Since you have access to the corresponding internal CAP issue, I suggest following this issue for status updates.
