Docker Swarm does not create container - docker

Question

I'm trying to create 3 zookeeper services in my docker swarm. However only managed to create 2 of the 3 containers:
docker ps -a returns:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
2c883f9148ff hyperledger/fabric-zookeeper:latest "/docker-entrypoint.…" 2 minutes ago Up 2 minutes 2181/tcp, 2888/tcp, 3888/tcp fabric_zookeeper1.1.td4wpq2t9uj5yjnw0q76gsqi0

docker network ls return:

With my container showing only 2 of my 3 zookeepers
I first create an overlay network
docker network create --attachable --driver overlay fabric
and ran the below docker compose file using command:
docker stack deploy -c docker-compose-zookeeper.yaml fabric

Answer 1

Found out that the container was created in my other nodes. But my container wasnt able to resolve address of the service
