Nextjs can not be reached from the host when deployed on docker swarm, but docker compose works totally fine.
docker service create and docker stack deploy both do launch the nodes and services but going to localhost:3000 results in nothing.

After a docker swarm init you can run docker service create -p 80:80 --replicas 1 --name nginx nginx and then visit localhost:80 (make sure to disable apache in wsl running sudo systemctl stop apache2.service in wsl terminal) you can see the nginx welcome page.

Using curl to go to localhost:3000 you get this:
curl: (52) Empty reply from server
