Building for two architectures in Docker

DockerBuildKit & BuildxMulti-archadvanced

What this snippet does

buildx produces a manifest list so each architecture pulls the right image.

Expected output

exporting manifest list sha256:9a2c... done

Why practise typing this

Typing buildkit & buildx code builds muscle memory for the symbols and indentation Docker uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
