docker 和 宿主机上 veth 设备的关系 + docker 网络架构

1. 在容器里查看

/ $ ip link show eth0
531: eth0@if532: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP 
    link/ether 02:42:ac:12:00:06 brd ff:ff:ff:ff:ff:ff
/ $ 

2.在主机查看

[root@slave1 ~]# ip link show | grep 532
532: veth598c5f9@if531: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master br-1b68951ea52c state UP mode DEFAULT group default 
[root@slave1 ~]# ip link show | grep 531
532: veth598c5f9@if531: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master br-1b68951ea52c state UP mode DEFAULT group default
