upload to google cloud storage using libcloud

Question

I wish to to upload files to google cloud storage. I created a service account, converted the p12 file to a pem file, then referenced the service account email address and pem file in my driver:

from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver


CloudStorage = get_driver(Provider.GOOGLE_STORAGE)
driver = CloudStorage(
    '...@developer.gserviceaccount.com',
    os.path.expanduser('~/.ssh/my.pem'),
    project='my_project',
)

however, when I do

driver.list_containers()

I get

<?xml version='1.0' encoding='UTF-8'?><Error><Code>InvalidSecurity</Code><Message>The provided security credentials are not valid.</Message><Details>Incorrect Authorization header</Details></Error>

apache-libcloud uses the S3 protocol for Google Storage.

This means you will need to enable Interoperability for Google Storage on the developer console.
