What this snippet does
Creating a dedicated account gives the service a home directory and a stable uid.
Expected output
uid=1000(app) gid=1000(app) groups=1000(app)
Why practise typing this
Typing users & security 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.
