docker之点到点的容器网络的配置

4: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN

7. 设置两个容器网络空间的ip

[root@liuxin-test01 ~]# ip netns exec 21682 ip addr add 192.168.99.1/32 dev A
[root@liuxin-test01 ~]# ip netns exec 21832 ip addr add 192.168.99.2/32 dev B

8. 启动两个容器的网络

[root@liuxin-test01 ~]# ip netns exec 21682 ip link set A up
[root@liuxin-test01 ~]# ip netns exec 21832 ip link set B up

9. 给这两个容器设置一下网关

[root@liuxin-test01 ~]# ip netns exec 21682 ip route add 192.168.99.2/32 dev A
[root@liuxin-test01 ~]# ip netns exec 21832 ip route add 192.168.99.1/32 dev B

10. 测试

[root@f64cdc7ffff1 /]# ping 192.168.99.2
PING 192.168.99.2 (192.168.99.2) 56(84) bytes of data.
64 bytes from 192.168.99.2: icmp_seq=1 ttl=64 time=0.095 ms

[root@cd4df383b68e /]# ping 192.168.99.1
PING 192.168.99.1 (192.168.99.1) 56(84) bytes of data.
