To install the buildx CLI plugin in the Docker container, you can simply download the correct version that matches your current CPU architecture from Github. As long as the “experimental” & “buildkit” config options in the docker config file are set to true, you should be able to access Buildx docker CLI plugin & buildkit from the terminal without any special setup.įor the CI pipeline, we can use a pre-built docker image with buildx CLI plugin installed. On your local dev PC (either x86 or apple M1 CPU), the easiest way to access “Buildx” & “BuildKit” is to install Docker Desktop. This allows us to build multi-CPU architecture docker images on one machine in one go. BuildKit is designed to work well for building for multiple platforms and not only for the architecture and operating system that the user invoking the build happens to run. “Buildx” Docker CLI plugin & Moby “BuildKit” builder toolkitĭocker Buildx is a CLI plugin that extends the docker command with the full support of the features provided by Moby BuildKit builder toolkit. Thus, even you don’t have a large ARM user base right now, it would still be a good long term investment to build a CI pipeline that can release docker images with ARM CPU support. Analysis shows an ARM-powered data center reduces CO2 production by 74%, equivalent to almost half a million barrels of oil. Besides the cost savings, what ARM-power data centres can bring us is more energy savings and a green future. And AWS Graviton claims its ARM CPU EC2 A1 instances offer up to 40% better price performance over comparable current-generation x86-based instances. Oracle Ampere A1 Compute claims its ARM instances offer up to 32% higher price performance over AMD Milan. We are also seeing more and more cloud providers offer ARM CPU based services. Although the M1 version docker desktop allows users to run x86 docker images under emulation, it will be a more efficient solution to offer your software as a “universal” Multi-Arch docker image that can serve both your ARM (M1) and x86 users. With Apple’s M1 machines getting popular, developers are receiving more requests for ARM CPU support for their software from their users.
