Invoke gcspypi using service account?

[JuergenSimon]

I would like to access own repositories in an automated deployment context or docker setup. For that I need a way to authenticate with the GCS without involving logging in as a user with the browser. Is there a way to authenticate using a service account?

I re-opened this issue after testing and confirming that this package does not work with service accounts. Try the following procedure to confirm:

• Create a service account with storage admin rights in IAM
• Create a key and download it (let's call it my-secret.json for now.
• In your terminal, call gcloud auth application-default revoke and confirm to make sure you are logged out
• Try to list your GCS repository using gcspypi --repository "my-rep" -v list. Result: an error message: failed connecting
• Activate the above service account: gcloud auth activate-service-account --key-file=my-secret.json
• List your GCS repository: gcspypi --repository "my-rep" -v list.
  => Expected: repository lists ok
  => What happens instead: error message: failed connecting

Only after logging in once and then logging out again it would work correctly.
