Create a new docker-compose.override.yml file and adjust below content for your configuration:

services:
  mdns-monitor:
    environment:
      TZ: 'UTC'
      WEB_ADDRESS: '0.0.0.0'
      WEB_PORT: 3000
# For macOS, use ports
#    ports:
#      - "5353:5353/udp" # Caution: macOS mDNS is already bound
#      - "3000:3000/tcp" # WEB_PORT above

WEB_ADDRESS sets the web interface listen address.
WEB_PORT sets the web interface listen port.
TZ sets the timezone inside the container.
Valid timezones inside the container are at /usr/share/zoneinfo.
