可以想象 3个容器的ip应该是172.17.0.1 172.17.0.2 172.17.0.3
查看运行的容器
linuxidc@linuxidc:~$ sudo docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
cebebc142a1b pc/mongod:master "usr/bin/mongod --no About a minute ago Up About a minute 22/tcp, 0.0.0.0:23117->27017/tcp rs_server3
b60c977313e1 pc/mongod:master "usr/bin/mongod --no About a minute ago Up About a minute 22/tcp, 0.0.0.0:22117->27017/tcp rs_server2

从上述信息可以看出本机的21117 22117 23117 映射到docker的容器的端口上去了
使用本机mongo客户端连接到21117
linuxidc@linuxidc:~$ mongo --port 21117
MongoDB shell version: 3.0.4
connecting to: 127.0.0.1:21117/test
开始配置 复制集的成员信息
> myconf = {"_id":"rs1","members":[
... {"_id":0,"host":"172.17.0.1:27017"},
... {"_id":1,"host":"172.17.0.2:27017"},
... {"_id":2,"host":"172.17.0.3:27017"}
... ]
... }
{
"_id" : "rs1",
"members" : [
{
"_id" : 0,
"host" : "172.17.0.1:27017"
},
{
"_id" : 1,
"host" : "172.17.0.2:27017"
},
{
"_id" : 2,
"host" : "172.17.0.3:27017"
}
]
}
初始化同步复制集群
> rs.initiate(myconf)
{ "ok" : 1 }
查看当前复制集的节点信息
rs1:OTHER> rs.isMaster()
{
"setName" : "rs1",
"setVersion" : 1,
"ismaster" : true,
"secondary" : false,
"hosts" : [
"172.17.0.1:27017",
"172.17.0.2:27017",

}
可以看出连接到的容器ip是172.17.0.1
也可以看见谁是主节点
