When watchtower detects that a running container needs to be updated it will stop the container by sending it a SIGTERM signal.
|
|
If your container should be shutdown with a different signal you can communicate this to watchtower by setting a label named _com.centurylinklabs.watchtower.stop-signal_ with the value of the desired signal.
|
|
|
|
This label can be coded directly into your image by using the `LABEL` instruction in your Dockerfile:
|
|
|
|
```docker
|
|
LABEL com.centurylinklabs.watchtower.stop-signal="SIGHUP"
|
|
```
|
|
|
|
Or, it can be specified as part of the `docker run` command line:
|
|
|
|
```bash
|
|
docker run -d --label=com.centurylinklabs.watchtower.stop-signal=SIGHUP someimage
|
|
```
