What this snippet does
A tag is just another name pointing at the same image id.
Why practise typing this
Typing cli: 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.
