Hi there!

We used Turboku to deploy a Heroku app with fly and almost everything worked seamlessly.

For loading a Google key we [used this solution](https://stackoverflow.com/a/62184769): in a .profile File we print an environment variable into a JSON-File.

Heroku automatically loads .profile files. Is there a way to achieve this with fly?

Hi @mariotrost! I’m not seasoned at this yet, but a sensitive environment variable sounds like it could be a job for [fly secrets](https://fly.io/docs/reference/secrets/).

@mariotrost I’m informed it may not be so simple if you need to get the key into the filesystem before boot. 🙃

Why can you not use the Google-recommended solution in the other answer in the Stack overflow question that you referenced: [Loading credentials from environment variables](https://github.com/googleapis/google-auth-library-nodejs#user-content-loading-credentials-from-environment-variables)?

Per @catflydotio suggestion, you’d create a secret in Fly with a value of the Service Account’s key, `JSON.parse` the key and then `auth.fromJSON` the result.

Thanks for the replies, @DazWilkin you’re totally right: the accepted answer on Stack overflow works for us!

For other APIs, there’s often an undocumented `{credentials: parsed_key_json}` argument to the constructor that works instead of the `auth.fromJSON` function.
