![]() ![]() “The new Docker Desktop on M1 is no exception you can build and run images for both x86 and Arm architectures without having to set up a complex cross-compilation development environment.”įor those of you lucky enough to already have an M1 in hand, the Docker Desktop for M1 tech preview is available for download, and the company says it expects it to be generally available in early 2021. “Docker has had support for multiplatform images for a long time, meaning that you can build and run both x86 and ARM images on Desktop today,” they write. ![]() multi-arch is now the default for the industry, as it always should have been They run a qemu x86 system model under the native Arm VM in order to do x86 builds, then both get pushed to e.g. Yes! It uses the same approach that they used to use for building Arm on x86. ![]() One of the big features users can look forward to with Docker Desktop on M1 is multiplatform development, which some users expressed some disbelief toward, but Docker points out that this has been the case for Docker all along. Now, the company has announced a tech preview of the new build, though it warns that it is “not release quality yet, or even beta quality,” but rather that they “wanted to let you try it as soon as possible.” According to the post, the company faced three big challenges, not the least of which being that they use Go extensively, which won’t support Apple Silicon until its 1.16 release, which is targeted for February 2021. With at least 1.5M of its users developing on Macs, Docker started working on building a new Docker Desktop that would work on the new architecture last month. ![]() If you haven’t yet read about Apple’s new M1 chip, the TLDR is that it is fast and powerful: “The new chip is said to offer 3.5 times the CPU and five times the graphics performance, as well as up to nine times faster processing for machine learning.” Using my M1 it took 17s including the push to the Docker Hub over my ISP using buildx. I just deployed a Go website that takes 2m55 to build natively on an RPi 4. What with the world such as it is - massive government-wide breaches and record daily COVID-19 deaths - we thought we’d kick off this week with just a bit of good news for you developers using Docker on your shiny new Macs: the tech preview of Docker Desktop for M1 is here and, so far, the reviews are good. ![]()
