С определением местоположения контенеров необходимо обеспечить авторизацию, для этого используются хранилища ключей.

dockerd – H fd:// —cluster-store=consul://192.168.1.6:8500 —cluster-advertise=eth0:2376

* —cluster-store – можно получать данные о ключах

* —cluster-advertise – можно сохранять

docker network create – driver overlay – subnet 192.168.10.
