# kill
|
||
|

```markdown
|
||
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")
|
||
```
|
||
|
||
## 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` and `CMD` in the *shell* form run as a child process 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`:
|
||
|
||
```bash
|
||
$ docker kill my_container
|
||
```
|
||
|
||
### Send a custom signal to a container
|
||
|
||
The following example sends a `SIGHUP` signal to the container named
|
||
`my_container`:
|
||
|
||
```bash
|
||
$ 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:
|
||
|
||
```bash
|
||
$ docker kill --signal=SIGHUP my_container
|
||
$ docker kill --signal=HUP my_container
|
||
$ docker kill --signal=1 my_container
|
||
```
|
||
|
||
Refer to the [`signal(7)`](http://man7.org/linux/man-pages/man7/signal.7.html)
|
||
man-page for a list of standard Linux signals.
