NextJS deploy fails with "Error failed to fetch an image or build from source: executing lifecycle: failed with status code: 51"

You are correct.

Docker has issues on an M1:

Can't compile Elixir App

Are you using local Docker to build this? You can tell in the very early part of the logs, it’ll either say “Using local Docker Daemon” or “Remote builder”. If it’s using local Docker, try adding --remote-only to see if our remote builders have more success. Docker on MacOS on m1 machines has all kinds of problems: Docker build fails when targeting `--platform linux/amd64`, due to `allocate virtual memory` issue · Issue #5831 · docker/for-mac · GitHub

Yep, I believe fly defaults to using local Docker if it’s available. And so that experience makes sense: once you added Docker locally, fly CLI noticed, and so used it. Until you said explicitly not to, by adding the --remote-only flag.

As for whether fly should detect it is running on an M1 (and so recommend using the remote builder instead) I agree that would be a nice improvement to avoid that issue.
