gargle (version 0.3.0)

credentials_gce: Get a token for Google Compute Engine

Description

Uses the metadata service available on GCE VMs to fetch an access token.

Usage

credentials_gce(scopes = NULL, service_account = "default", ...)

Arguments

scopes

A character vector of scopes to request. Pick from those listed at https://developers.google.com/identity/protocols/googlescopes.

For certain token flows, the "https://www.googleapis.com/auth/userinfo.email" scope is unconditionally included. This grants permission to retrieve the email address associated with a token; gargle uses this to index cached OAuth tokens. This grants no permission to view or send email. It is considered a low value scope and does not appear on the consent screen.

service_account

Name of the GCE service account to use.

...

Additional arguments passed to all credential functions.

Value

A GceToken() or NULL.
