@angrylogic I've been using this fork for a bit, works well! 😄

Have you thought about extending it to also configure the GCP auth config as well? So actually giving it the credentials file: https://www.vaultproject.io/api/auth/gcp/index.html#configure

So doing this step but with Terraform:

vault auth enable 'gcp'
vault write auth/gcp/config credentials=@vault_auth_checker_credentials.json

Then, you could do the entire process of Vault in GCP with Terraform:

resource "vault_auth_backend" "gcp" {
    path = "gcp"
    type = "gcp"
}

resource "google_service_account_key" "vault_auth_checker_credentials" {
  service_account_id = "${google_service_account.vault_auth_checker.name}"
  public_key_type = "TYPE_X509_PEM_FILE"
}

resource "vault_auth_backend_gcp_config" gcp {
   credentials = "${base64decode(google_service_account_key.vault_auth_checker_credentials.private_key)}"
}

We're interested in this aswell... Any plans to get this merged?

@tyrannosaurus-becks -- rebased and addressed feedback in this one as well.

Tests passing for me:

$ go test -test.v -run TestGCPAuthBackendRole_basic
=== RUN   TestGCPAuthBackendRole_basic
--- PASS: TestGCPAuthBackendRole_basic (0.18s)
PASS
ok      github.com/terraform-providers/terraform-provider-vault/vault   0.300s

Thanks!
