Couchbase shutdown in docker swarm

Couchbase Server

Running couchbase in a docker swarm shots down. Following this

I do the following on/in docker swarm:

docker network create -d overlay couchbase

docker service create --name couchbase-master -p 8091:8091 --replicas 1 --network couchbase -e TYPE=MASTER arungupta/couchbase:swarm

I can see that it is down with:

docker service ps couchbase-master

Note: I can run nginx and other services. Do you know how to debug/ see the log from Couchbase(not just the log from docker service logs)
