If run inside a docker-compose setup, the watchdog will notify the configured Slack channel about its shutdown.
To get the watchdog, simply pull the
hackaburg/watchdog image from the Docker hub and pass in your Slack webhook url as an environment variable:
$ docker run \ --rm \ -it \ -e SLACK_WEBHOOK_URL=https://your-slack-webhook_url \ hackaburg/watchdog
