What this snippet does
BuildKit only builds stages the target depends on, so nothing from an unused stage is present.
Expected output
/bin/sh: jq: not found
Why practise typing this
Typing multi-stage builds 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.
