Running in docker compose, I see that the entire server is booted, the service starts but then shuts down. If I docker compose down && docker compose up -d, it runs fine.
Why does træfik decide "I have to go..." and then shutdown during server boot?
docker-compose.yaml:
services:
reverse-proxy:
# I also tried with:
# image: traefik:latest
image: traefik:v3.1.2
command: --log.level=DEBUG

This does not provide any hints about why it decides "I have to go...".
I have 14 other docker containers that behave nicely at boot as far as I can tell.
