kill

Usage: docker kill [OPTIONS] CONTAINER [CONTAINER...]

Kill a running container using SIGKILL or a specified signal

  --help                 Print usage
  -s, --signal="KILL"    Signal to send to the container

The main process inside the container will be sent SIGKILL, or any signal specified with option --signal.

Note: ENTRYPOINT and CMD in the shell form run as a subcommand of /bin/sh -c, which does not pass signals. This means that the executable is not the container’s PID 1 and does not receive Unix signals.
