Overriding ENTRYPOINT in Docker

What this snippet does

--entrypoint replaces the baked-in entrypoint, which is the usual way into a misbehaving image.

Expected output

server.js
package.json

Why practise typing this

Typing cmd & entrypoint 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.
