What this snippet does
Without a credential helper, docker login writes base64-encoded credentials to disk.
Expected output
"auths": { "registry.example.com": { "auth": "dXNlcjpwYXNz" } }Why practise typing this
Typing registry & tagging 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.
