Mattermost Notifications
Mattermost is currently supported through Apprise. See the documentation for all posible options.
An example configuration is:
version: "3"
services:
  apprise: # (1)!
    image: caronc/apprise:latest
  dolce:
    image: dangrie158/dolce:v2.6.0
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      APPRISE_HOST: apprise:8000
      APPRISE_URLS: mmosts://mattermost.server.local/3ccdd113474722377935511fc85d3dd4 # (2)!
- Dolce relies on the external Apprise container to send notifications to Mattermost. This is only the simplest example.
 - See the documentation for a full overview on how you can customize the notifications
