Passing sensitive information to cloud functions : <p>Is there an "official" solution for passing sensitive information, such as API keys, to Google Cloud Functions? In particular it would be nice to avoid passing this information as arguments to the function since it will be the same for every invocation. AWS Lambda has a <a href="http://docs.aws.amazon.com/lambda/latest/dg/tutorial-env_console.html" rel="noreferrer">built-in solution</a> using encrypted environment variables for this. Is there some similar approach for Google Cloud Functions?</p>

<p>I could imagine using a cloud storage bucket or cloud datastore for this, but that feels very manual.</p>
