Accessing images on registry.fly.io

Questions / Help
2

I don’t know if a regular fly deploy results in an easy-to-reuse image, but you can pretty easily use regular Docker to build an image and store it on fly.io registry. I create a separate “app” for container images

docker build --push -t http://registry.fly.io/<myorg>-containers:appB .

Then in a Dockerfile:
FROM registry.fly.io/myorg-containers:appB

And use fly auth docker to auth with registry
