  title: docker kill

  Usage:  docker kill [OPTIONS] CONTAINER [CONTAINER...]
  
  Kill one or more running containers
  
  Options:
    --help            Print usage
  -s, --signal string   Signal to send to the container (default "KILL")
  

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.
