From security stand point of view, does it make a difference if one deploys the app from a local Dockerfile or from a private docker image from docker hub? Thanks.

Fly.io doesn’t support private images, unfortunately, except for their own `registry.fly.io`.

The `skopeo` utility from the [previous thread](https://community.fly.io/t/how-to-delete-old-releases/24312) can copy from one to other, though. (I’ve used a variant of that several times myself, with Guix-built images.)

This is lighterweight alternative to using an entire Docker setup just to do the initial pull—which some other users were (understandably) [dissatisfied with…](https://community.fly.io/t/feature-request-images-from-private-docker-registries/842/11)
