文档手动配置网络--陈奇网络工作室

云计算

创建没有网络配置的容器

[ root @ localhost~~ ] # docker run-I-t-- RM-- net=nonealpinesh

//#

打开另一个终端

显示容器id

[root@localhost ~]# docker ps -a

查找进程id

[ root @ localhost~] # docker inspect-f\& amp； quot； {.state.PID}\\&amp； quot； 2aefc41dbdeb

9076

[root@localhost ~]# pid=9076

创建命名空间

[ root @ localhost~] # mkdir-p/var/run/net ns

[ root @ localhost~] # ln-s/proc/$ PID/ns/net/var/run/net ns/$ PID

显示网桥NIC的IP和子网掩码信息

[ root @ localhost~] # ipaddrshowdocker 0

5: docker0: NO-CARRIER，BROADCAST，MULTICAST，UP mtu 1500 qdisc noqueue state DOWN

link/ether 02:42:8e:E7:64:4 ABR dff:ff:ff:ff:ff:ff:ff

inet 172.18.0.1/16 brd 172.18.255.255 scopeglobaldocker 0

valid _ lftforeverpreferred _ lft forever

创建" veth pair "接口a和b对

[ root @ localhost~] # sudoiplinkaddatypevethpeernameb

a将接口绑定到网桥docker0

[ root @ localhost~] # sudobrctladdifdocker 0a

启用

[ root @ localhost~] # sudoiplinksetaup

将b接口放在容器的网络名称空间中

[ root @ localhost~] # sudoiplinksetbnetns $ PID

命名为eth0

[ root @ localhost~] # sudoipnetnsexec $ pidiplinksetdevbnameeth 0

打开网络接口b

[ root @ localhost~] # sudoipnetnsexec $ pidiplinkseteth0up

配置可用的桥接网段( IP )

[ root @ localhost~] # sudoipnetnsexec $ pidipaddradd 172.18.0.99/16 deveth 0

配置默认网关

[ root @ localhost~] # sudoipnetnsexec $ pidiprouteaddefaultvia 172.18.0.1

最后，返回容器并验证网卡的配置
