1、etcd配置

grep -v '^#' /etc/etcd/etcd.conf

ETCD_NAME=default
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"
ETCD_ADVERTISE_CLIENT_URLS="http://0.0.0.0:2379"
ETCD_LOG_PACKAGE_LEVELS="ecurity=DEBUG"

2、etcd创建子网键值记录
etcdctl mk /coreos.com/network/config '{"Network": "172.17.0.0/16"}'

3、各个节点的flannel配置

grep -v '^#' /etc/sysconfig/flanneld

FLANNEL_ETCD="http://192.168.2.30:2379"
FLANNEL_ETCD_KEY="/coreos.com/network"
FLANNEL_OPTIONS=""

4、查看节点

docker-02节点获取的地址

ifconfig docker0

docker0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1472
inet 172.17.60.1 netmask 255.255.255.0 broadcast 0.0.0.0
inet6 fe80::42:98ff:fedc:7ff6 prefixlen 64 scopeid 0x20<link>

ifconfig flannel

flannel0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1472
inet 172.17.60.0 netmask 255.255.0.0 destination 172.17.60.0
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 500 (UNSPEC)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

docker-03节点获取的地址

ifconfig docker0

docker0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1472
inet 172.17.60.1 netmask 255.255.255.0 broadcast 0.0.0.0
inet6 fe80::42:d4ff:fec2:388b prefixlen 64 scopeid 0x20<link>
ether 02:42:d4:c2:38:8b txqueuelen 0 (Ethernet)
RX packets 11 bytes 752 (752.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 8 bytes 648 (648.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

ifconfig flannel

flannel0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1472
inet 172.17.60.0 netmask 255.255.0.0 destination 172.17.60.0
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 500 (UNSPEC)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

问题： 为什么这两个节点获取的地址相同，docker0的地址按理说不同的？还是我哪里配置的不对，请大神帮看看啊，感谢！
