OCI standard labels let registries and tooling link an image back to its source.
Expected output

Why practise typing this
Typing runtime configuration 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.
