Expect my newly reconfigured docker host to become the swarm leader AND exposes port 2377 to the outside world.
swarm started and all services work as expected, but: port 2377 is not reachable from the outside world. (Not even from the inside world: ‘lsof -i -P -n | grep LISTEN’ doesn’t show any open port 2377 on any ethernet card.)
Am I doing something wrong? Would like to connect a second host…
