# kill
Usage: docker kill [OPTIONS] CONTAINER [CONTAINER...]
Kill a running container using SIGKILL or a specified signal
--help=false 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 containers PID 1
> and does not receive Unix signals.
