I would like to use Swarm with only one node to do rolling updates but I even if I can connect to a service’s port, the service doesn’t respond.
I created a swarm with docker swarm init --listen-addr <my_lan_ip> --advertise-addr <my_lan_ip>.
If I run redis normally (docker run -it --rm -p 6379:6379 redis), the port is open and redis responds when I send ‘INFO’.
If I run redis as a service (docker service create -p 6379:6379 --name redis redis), the port is open but redis doesn’t respond.
Am I doing something wrong or is it a bug?
