### Configuring docker stop timeout
[By default](https://docs.docker.com/engine/reference/commandline/stop/), docker will wait 10 seconds from the time the `stop` command is passed to a container before it attempts to kill said container. This timeout can be configured on a per-app basis in dokku by setting the `DOKKU_DOCKER_STOP_TIMEOUT` configuration variable. This timeout applies to normal zero-downtime deployments as well as the `ps:stop` and `apps:destroy` commands.
```
$ dokku config:set $APP DOKKU_DOCKER_STOP_TIMEOUT=20
```
