What this snippet does
Removing a container does not remove its anonymous volumes, so disk usage creeps up.
Expected output
Total reclaimed space: 1.412GB
Why practise typing this
Typing volumes & storage 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.
