Update GCP env var for credential path in Getting started guide

[draconteus]

Hi,

Opening a new PR requested by @megan07. This issue needs further investigation.
TL;DR: Using GOOGLE_CLOUD_KEYFILE_JSON env var is not working for finding credential file

History can be found in: #5021

Cheers :)

Hi @draconteus! Thanks again for opening this new PR, I appreciate it. Are you going through the "Getting Started with the Google Provider" guide? If so, I've gone through those steps after clearing my environment variables. After running export GOOGLE_CLOUD_KEYFILE_JSON=path/to/creds.json, I have not had a problem. I did get the error when GOOGLE_CLOUD_KEYFILE_JSON was not set, so after you run the export command, could you do an echo $GOOGLE_CLOUD_KEYFILE_JSON and make sure it's the same path that you're using when you used GOOGLE_CREDENTIALS?

[draconteus]

Yeah, I did that's how I recognised this problem. Also, it was the first thing to check if this env var was set properly. One thing that comes to my mind that I don't gave gsutil installed. I don't any internal working of gsutil or terraform, thus I don't know which tool checks the GOOGLE_CLOUD_KEYFILE_JSON var. But setting neither GOOGLE_CLOUD_KEYFILE_JSON nor GCLOUD_KEYFILE_JSON like it stated in the Docs (https://www.terraform.io/docs/providers/google/guides/provider_reference.html#credentials-1).

@megan07 @draconteus As per https://cloud.google.com/docs/authentication/getting-started, GOOGLE_APPLICATION_CREDENTIALS is used to provide the JSON Key for service account.

[draconteus]

Ooo, okay, yeah I used service account's credentials. Thanks for finding this @pradeepbhadani!

[megan07]

@draconteus , interesting. I'm not sure why GOOGLE_CLOUD_KEYFILE_JSON would not work or is throwing an error, since it follows the same codepath as GOOGLE_CREDENTIALS . If the file was in the wrong format it should still throw an error.
However, it looks like the issue is resolved, can we close?

[draconteus]

Yeah, sure :)

Thanks!
