Extended description
The docker kill
subcommand kills one or more containers. The main process inside the container is sent SIGKILL
signal (default), or the signal that is specified with the --signal
option. You can kill a container using the container’s ID, ID-prefix, or name.
Note:
ENTRYPOINT
andCMD
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.
Examples
Send a KILL signal to a container
The following example sends the default KILL
signal to the container named my_container
:
$ docker kill my_container
Send a custom signal to a container
The following example sends a SIGHUP
signal to the container named my_container
:
$ docker kill --signal=SIGHUP my_container
You can specify a custom signal either by name, or number. The SIG
prefix is optional, so the following examples are equivalent:
$ docker kill --signal=SIGHUP my_container
$ docker kill --signal=HUP my_container
$ docker kill --signal=1 my_container
Refer to the signal(7)
man-page for a list of standard Linux signals.
