In Docker Desktop, when you start a container with a not-yet-initialized volume, Docker [automatically initializes](https://docs.docker.com/storage/volumes/#populate-a-volume-using-a-container) that volume with the files that are in the container image at the directory path where the volume will be mounted.

[Fly.io](http://Fly.io) doesn’t do that, requiring the container’s entrypoint to [perform](https://fly.io/docs/laravel/the-basics/laravel-volume-storage/) such initialization.

Since [Fly.io](http://Fly.io) generally tries to create a UX that’s familiar to people who already know Docker, it would be great if [Fly.io](http://Fly.io) matched Docker’s behavior by also automatically initializing the volume like Docker does.
