Answer
ENTRYPOINT defines the primary executable, while CMD provides default arguments. If both exist, CMD arguments are passed to ENTRYPOINT.
Quick Answer
CMD sets the default command run at container startup — fully replaceable when you pass a command to docker run. ENTRYPOINT sets a fixed entry command that always runs — additional arguments from CMD or docker run are appended to it. ENTRYPOINT is for defining what the container IS; CMD is for its default behavior.
