宿主机ping不同keepalived

Question

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
       valid_lft forever preferred_lft forever
2: tunl0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1
    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 ::
40: eth0@if41: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
    link/ether 02:42:ac:12:00:07 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    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
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.18.0.7  netmask 255.255.0.0  broadcast 172.18.255.255

你在Mac上用的是vmware虚拟机跑docker吗？

• 提问者 ellydebug #1

  没有用虚拟机，直接跑的docker

• 神思者 回复 提问者 ellydebug #2

  这个不行，虚拟IP要在Linux系统上使用，装vmware虚拟机吧

  非常感谢！
