docker+ swarm + etcd 集群的问题

环境信息

服务器:

• 192.168.99.100 centos-node1

• 192.168.99.101 centos-node2

• 192.168.99.102 centos-node3

集群信息:

• etc服务器: 192.168.99.100:2379

• swarm manage: 192.168.99.101:2376

准备

• 在所有的机器上安装dokcer

• 在centos-node1 上docker pull ystyle/etcd （和 quay.io/coreos/etcd:v2.2.5上的是一样的。）

• 在所有机器上dokcer pull swarm

安装etcd k-v数据库

在centos-node1上执行:

export HOSTIP=192.168.99.100
docker run -d -v /usr/share/ca-certificates/:/etc/ssl/certs -p 4001:4001 -p 2380:2380 -p 2379:2379 \
 --name etcd ystyle/etcd \
 -name etcd0 \
 -advertise-client-urls http://${HOSTIP}:2379,http://${HOSTIP}:4001 \
 -listen-client-urls http://0.0.0.0:2379,http://0.0.0.0:4001 \
 -initial-advertise-peer-urls http://${HOSTIP}:2380 \
 -listen-peer-urls http://0.0.0.0:2380 \
 -initial-cluster-token etcd-cluster-1 \
 -initial-cluster etcd0=http://${HOSTIP}:2380 \
 -initial-cluster-state new

分别在三个节点执行： 加入集群

docker run -d swarm join --addr=192.168.99.100:2375 etcd://192.168.99.100:2379/swarm
docker run -d swarm join --addr=192.168.99.101:2375 etcd://192.168.99.100:2379/swarm
docker run -d swarm join --addr=192.168.99.102:2375 etcd://192.168.99.100:2379/swarm

在centos-node2上启动swarm manage

dokcer run -d -p 2376:2375 swarm manage -H=0.0.0.0:2375 etcd://192.168.99.101:2379/swarm

然后发现不管用集群执行什么命令都没反应， 没有报错，pull不成功， images 里也是空的。

docker info 信息也很奇怪：

swarm 节点只能看到两个

#docker run --rm swarm list etcd://192.168.99.100:2379/swarm
time="2016-03-16T14:19:41Z" level=info msg="Initializing discovery without TLS" 
192.168.99.101:2375
192.168.99.102:2375

这是怎么怎么回事？ 还是我有步骤没做或漏了？
