What this snippet does
Alpine ships musl instead of glibc, so many wheels have no prebuilt binary and must compile from source.
Expected output
error: command 'gcc' failed: No such file or directory
Why practise typing this
Typing base images 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.
