Container start command in one line:

docker run -it --pull always --restart unless-stopped --name mhddos_proxy ghcr.io/porthole-ascend-cinnamon/mhddos_proxy -t 4000 --itarmy --table

Container logs check:

docker logs mhddos_proxy -f --tail 10

And you do not need docker-compose You can add that command to user-data yml and start server automatically.

If you need restart fully restart container at start:

docker stop mhddos_proxy ; docker rm mhddos_proxy ; docker run -d -it --pull always --restart unless-stopped --name mhddos_proxy ghcr.io/porthole-ascend-cinnamon/mhddos_proxy:latest -t 4000 --itarmy --table
