I'm trying this out now.
One question: when I ran "flyctl deploy" it said "Docker daemon available, performing local build..."
If I turn off my local Docker, would it instead just upload the Dockerfile somewhere and perform the build for me?
If so, is there a way to force it to do that? I'd much rather upload a few hundred bytes of Dockerfile than build and push 100s of MBs of compiled image from my laptop.
