Add amd64/v3 builder for apple silicon #2566

Open klnusbaum opened 2 days ago

Description

Currently, if I try to build a container image on apple silicon using the amd64/v3 builder, I get the following error:

ERROR: failed to solve: no support for running processes with linux/amd64/v3 platform, supported: linux/amd64, linux/amd64/v2

I'd like to be able to build using amd64/v3, but looking at the available builders, it appears only up to v2 is supported:

Would it be possible to add support for amd64/v3?

Support for this doesn't depend on us but what amd64 instructions the emulator (rosetta or qemu-user) can emulate. This is automatically detected based on chip capabilities. You can still use cross-compilation if you want to create amd64/v3 images but you can't run emulated containers that are amd64/v3 capable.
