What this snippet does
nginx drains connections on SIGQUIT, so STOPSIGNAL makes docker stop graceful.
Expected output
nginx: gracefully shutting down
Why practise typing this
Typing healthcheck & signals 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.
