Docker将container同时加入两个网络 ​

需求 ​

让container加入两个网络

实现 ​

如果使用docker run来实现.好像是不行的,因为--network只能指定一个网络

可以使用docker network connect来进行连接

创建两个网络 ​

shell
[root@docker ~]# docker network create --subnet 10.0.1.0/24 --gateway 10.0.1.10 test-1

[root@docker ~]# docker network create --subnet 10.0.2.0/24 --gateway 10.0.2.10 test-2
fc67eed08df58adf69279e64845136373aea5cfebea3d5e5001acd4609ff2ea5
  • --subnet指定网段
  • --gateway指定网关

创建一个Container ​

shell
[root@docker ~]# docker run -d  --name test --network test-1 --rm -d busybox sleep 600
[root@docker ~]# docker exec test ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000
    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
53: eth0@if54: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue 
    link/ether 02:42:0a:00:01:01 brd ff:ff:ff:ff:ff:ff
    inet 10.0.1.1/24 brd 10.0.1.255 scope global eth0
       valid_lft forever preferred_lft forever

将其加入另外一个网络 ​

shell
[root@docker ~]# docker network connect test-2 test
[root@docker ~]# docker exec test ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000
    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
53: eth0@if54: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue 
    link/ether 02:42:0a:00:01:01 brd ff:ff:ff:ff:ff:ff
    inet 10.0.1.1/24 brd 10.0.1.255 scope global eth0
       valid_lft forever preferred_lft forever
55: eth1@if56: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue 
    link/ether 02:42:0a:00:02:01 brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.1/24 brd 10.0.2.255 scope global eth1
       valid_lft forever preferred_lft forever
