Hey everyone! I'm trying to figure out the best way to manage API or library keys using Docker secrets. I can't just rely on process.env directly in my code. It seems like certain libraries automatically try to access process.env during their launch, and I'm worried that most libraries operate this way. How can I effectively use Docker secrets in this scenario?

Docker Secrets are primarily designed to be accessed as file content, which is why many Docker images provide an environment variable option with a `_FILE` suffix that points to the secret file, typically located at `/run/secrets/SECRET_NAME`. It's important to note that exporting them as environment variables could compromise their security, so it’s best to avoid that approach.
The secrets are actually mounted as files in the container, so you can name them however you want. If your application expects certain environment variables, simply mount the secret in the path that process.env anticipates.
