[神灵e叹息]

docker Server Version: 17.06.2-ce
centos7 Linux dk 4.4.88-1.el7.elrepo.x86_64
[root@dk ~]# docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
a858gqzl7t1byagtg9kit3oyk * dk Ready Active Leader
uqi8rompb3ctj8m8ubhudr5qv docker140 Ready Active
docker 的overlay网络如下：
[root@dk ~]# docker network inspect mynet1
[
{
"Name": "mynet1",

}
]
},

},
{

"IP": "192.168.0.70"
}
]
}
]
[root@dk ~]# docker service create --replicas 2 --name mytest --network mynet1 centos
创建OK的service
[root@dk ~]# docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
szoxi0wygl3l mytest replicated 0/2 centos:latest

这是要让人崩溃啊
看message日志
报如下错误:
