If you're not running traefik using docker, you might want a systemd service file for it.

traefik.service

# 
# assumes you have a user called 'traefik', with the home directory '/var/lib/traefik',
# containing the 'traefik' executable and a 'trafik.toml' configuration file.
## adduser --system --shell /sbin/nologin --home /var/lib/traefik traefik 
#
