Swift app built with `flyctl deploy -local-only` fails

Questions / Help Build debugging

Hello, Here is the repo that reproduces the issue https://github.com/atacan/reproduce-fly-local-deploy-build-issue with details.

This is a Swift server application. Direct docker build works just fine. Fly local deploy takes too long and fails. In the above example I didn’t wait for it to fail.

A similar app worked fine with remote builder, after failing with the local fly deploy.

Thank you for making the repro repository!

fly deploy --local-only makes a container image for x86_64 (aka Intel) on Apple silicon, whereas docker-compose up app --build builds a container images for Apple silicon by default. So the emulation process on the former may make the build slower.

We need to have container images for x86_64, because all our servers are x86_64.
