Swarm

【求助】docker 1.12 swarm 部分节点容器互联异常

swarm集群三台机器

ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS

3amd7159bqbef6jjuqtzvkc9b    i2        Ready   Active        

92qhm6qhvtlrg9y3cqhudi20w *  i1        Ready   Active        Leader

eplawj2jqyyblgaxv57ass39m    i3        Ready   Active

二个service，分别是zookeeper和1个web，web依赖zk

docker service create \

--name zk \

--env MYID=1 \

--env SERVERS=zk \

--network my-network \

--endpoint-mode dnsrr \

mesoscloud/zookeeper

docker service create \

--name dubboadmin \

--network my-network \

--publish 18112:8080 \

--endpoint-mode vip \

dubboadmin:1.0

web scale了4份，分布在2个节点

docker service ps dubboadmin
ID                         NAME          IMAGE                              NODE  DESIRED STATE  CURRENT STATE                   ERROR

问题
i1节点上的容器都报异常

i2节点上的容器正常，ping zk正常
