Why can’t you update the Docker image to also support ARM? You theoretically could switch your backend to run ARM Linux. However, this would take months - renting out ARM instances, re-building all repositories, and a tense switch over. What if your hosting provider doesn’t offer ARM instances with the same system requirements as x86_64? What if you complete this migration and find it runs at half the speed?<\/p>\n

Worse, it might be impossible if your images include files downloaded off the internet, as those are often only compiled for x86_64.<\/p>\n

Boot Camp will definitely not be available on ARM Macs<\/a>. It might be added later with the ability to run ARM Windows, though Microsoft would have to approve<\/a>.<\/p>\n<\/blockquote>\n\n

With the Mac having the same hardware as the target devices, there’s consistency and no hidden surprises. Whenever the development cycle is shortened and opaque differences removed, it’s a good thing.<\/p>\n

What about the downside of Docker becoming 2 to 5x slower without hypervisor? While that is indeed a downside, I’d argue that for local Docker instances, they are better used for functional testing and not part of the core development cycle.<\/p><\/blockquote>\n\n
