GCP Support

[asyd]

Hello Jan-Christoph, it's me again :)

Have you planned to support others providers than aws, like GCP by chance?

Cheers

Hi @asyd.

I am happy to support GCP, but I'd appreciate some information about the GCP provider from you, since I haven't used GCP yet really:

1. I have seen there is google and google-beta (https://www.terraform.io/docs/providers/google/index.html), do you need both?

2. What parameters (credentials, region, etc) are required to configure the GCP provider? I'd like to make those configurable via environment variables for now (for AWS those environment variables are, as mentioned in the README, for example, AWS_PROFILE, AWS_DEFAULT_REGION, etc.

1. At this moment google will be enough for me
2. A project_id (can be an environment variable), and a credentials file (usually a JSON one)

Thanks @jckuester

FYI, I opened PR #3, but it's not working for me, yet.

When I run GOOGLE_REGION=us-central1 GOOGLE_CREDENTIALS=some-credentials.json terradozer -debug terraform.tfstate, I get

      • using state                                        file=test/test-fixtures/single-resource-gcp/terraform.tfstate

Not sure what's missing yet...
