Use only overlay network to run in cluster mode. If exact network is defined in docker-compose file, like bridge network, it should be created as follows. Skip if overlay is used.

sudo docker network create  \

--gateway 10.10.1.1 \
-o com.docker.network.bridge.enable_icc=false \
-o com.docker.network.bridge.name=docker_gwbridge \
