First of all, we need to make sure that we have an authentication file on the host, we can check it by checking if the auth file exists:

cat ~/.config/gcloud/application_default_credentials.json # Linux

The output should look like this:

{
"client_id": "<ID>.apps.googleusercontent.com",
"client_secret": "<SECRET>",
"refresh_token": "<TOKEN>",
"type": "authorized_user"
}

If the file does not exist, you can create it by authenticating to Google using the following gcloud command from the host.

  • make sure you have gcloud installed on your machine.
gcloud auth application-default login

That saves the authentication data into a file.

Now we want to mount our authentication file to our container, all we need to do is edit the docker-compose.yml and add the following lines:

volumes:
- ~/.config/:/root/.config

This will make the `google-cloud` package look in the right path for authentication.

That it!

Great success!
