alert plugins are not loaded

I was trying to install https://github.com/vikingco/cabot-alert-victorops. I followed the steps outlined in the Readme (adapted to the container):

1. Enter the cabot virtual environment.
2. Run pip install cabot-alert-victorops (in Dockerfile instead)
3. Add cabot_alert_victorops to the installed apps in settings.py (instead: ENV CABOT_PLUGINS_ENABLED=cabot_alert_hipchat,cabot_alert_twilio,cabot_alert_email,cabot_alert_victorops)
4. Run manage.py syncdb (not necessary, run in run.sh)
5. Set VICTOROPS_URL and VICTOROPS_API_KEY environment variables (again in Dockerfile)
6. Restart Cabot (not necessary, is started later anyway)

However, the plugin is never loaded.

Using some very troublesome println-debugging, I managed to figure out that the plugin file is imported, but the class is not registered to AlertPlugin.__subclasses__().

Adding the plugin works flawlessly in the development Vagrant box.

Try to docker-compose build --no-cache && docker-compose up -d
Also better way use cabot_env file for envs
