🔍 Logging with journalctl

All Docker Compose actions triggered by this role are logged to the system journal using systemd-cat. Output is simultaneously shown in the terminal and available via journalctl.

To view logs for a specific application:

journalctl -t docker-compose-<application_id> -f

Replace <application_id> with the actual project name (e.g. discourse, nextcloud, etc.).

This enables persistent and searchable logs for all container setups and rebuilds.
