修改kercentos7配置和宿主机同网段IP

docker centos 7配置和宿主机同网段IP

1、安装brct l命令

#yum-yinstal l bridge -uti ls

2、编辑网卡配置文件

#cat ifcfg-eno167 77736

TYPE=Ethern et

IPV4_F AILURE _FATAL =no

IPV6IN IT=yes

IPV6_A UTOCON F=yes

IPV6_D EFROUT E=yes

IPV6_P EERDNS =yes

IPV6_P EERROU TES=yes

IPV6_F AILURE _FATAL =no

NAME=eno167 77736

UUID=2b0450 3d-4c0d-4f0f-8790-7b6203 739892DEVICE =eno167 77736

ON BOOT =ye s

B RI D G E =b r0

#cat ifcfg-br0

DEVICE =br0

TYPE=Bridge

BOOTPR OTO=static

ON BOOT =ye s

D E LAY=0

STP=yes

IPADDR =192.168.1.144

NETMAS K=255.255.255.0

GATEWA Y=192.168.1.1

3、重启相关服务 以及关闭相关服务

#system ctl stop Networ kManag er

#system ctl disabl e Networ kManag er

#system ctl restar t networ k b r0正常启动能够正常访问该机器即可再用下面命令查看有即可

#brctl show bridge namebridge id STPenable d interf aces br08000.000c29 ebab05 yeseno167 77736

4、修改dock er配置文件 修改桥接的网卡以及IP分配范围

#vim/etc/syscon fig/docker

将

OPTION S='--sel inu x-enable d'

修改为

OPTION S='--sel inu x-enable d-b=br0--fixed-cidr=192.168.1.192/26'重新启动do cker

#system ctl stop docker .servic e

#system ctl start docker .servic e

5、启动dock er实例

#docker run -i -tcentos /bin/bash

#ipaddrshoweth0
