Diff between docker stop and docker kill?

Docker stop command stops the container gracefully and safely. It is not abruptly shut the containers. In this case four events triggers kill, die, disconnect network and stop container. It will send SIGTERM signal(28). If in case if it couldn't stop container in certain time then it kills the container.

docker stop containerid

Docker kill command kills the container abruptly and in unsafe manner. It will directly kills the container and send 3 events which are kill, die and disconnect network. It actually send SIGKILL(9) signal to kill container immediately

docker kill containerid
