mac电脑，成功启动keepalived后，其它容器可以ping通keepalived，但是宿主机ping不通。
在haproxy容器内，执行：ip add 看到如下信息：

root@a9cea49008cf:/# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    link/ipip 0.0.0.0 brd 0.0.0.0
3: ip6tnl0@NONE: <NOARP> mtu 1452 qdisc noop state DOWN group default qlen 1
    link/tunnel6 :: brd ::

    inet 172.18.0.7/16 brd 172.18.255.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet 172.18.0.209/32 scope global eth0
       valid_lft forever preferred_lft forever

执行ifconfig，显示如下

root@a9cea49008cf:/# ifconfig
