I'm trying to run Neo4j in HA mode using Azure Container Service + Docker. To run mode is required HA 3 instances within the same network.
I create a network with the command:
docker network create --driver = bridge cluster
But when trying to associate instances of this network I got the following error:
docker: Error response from daemon: network cluster not found.
I've tried with the network ID and does not work.
I'm following this tutorial: https://neo4j.com/developer/docker-3.x/ but without success. Something tip?
ps .: Running in sigle mode works.
Commands and result I get.

The problem in azure with docker was because I'm doing the test with a cluster of machines.
So the command: docker network create --driver = bridge cluster does not serve for this purpose.
We can must use the --driver = overlay to function as multi-host.
