Traefik container and log rotation

Traefik Traefik v2 (latest)
1

Hello all,
I'm running Traefik in docker and my logs have grown to over 2.5GB without realising. I use Promtail to collect logs to Loki. How would I go about sending Traefik the USR1 signal to rotate logs and can Promtail do that?

Thanks in advance
