Log management and configuration.

Log Output

Tux uses Loguru for structured logging.

Docker Compose

# View logs
docker compose logs -f tux

# Last 100 lines
docker compose logs --tail=100 tux

# Since timestamp
docker compose logs --since 2024-01-01T00:00:00 tux

Systemd

# Follow logs
sudo journalctl -u tux -f

# Last hour
sudo journalctl -u tux --since "1 hour ago"

# Search for errors
sudo journalctl -u tux | grep ERROR

Log Levels

Configure via DEBUG environment variable:

DEBUG=false                         # INFO level (production)
DEBUG=true                          # DEBUG level (development)

Levels:

  • DEBUG - Detailed diagnostic info
  • INFO - General operational messages
  • WARNING - Warning messages
  • ERROR - Error messages
  • CRITICAL - Critical failures

Log Rotation

Docker Compose includes log rotation by default:

logging:
  driver: json-file
  options:
    max-size: "10m"
    max-file: "3"
    compress: "true"
