docker(18)：用PIPEWORK为docker容器配置独立IP

参考文档：http://blog.csdn.net/design321/article/details/48264825

官方网站：https://github.com/jpetazzo/pipework

宿主环境：centos7.6

1 安装pipework

git clone https://github.com/jpetazzo/pipework.git
cd pipework/
cp pipework /usr/local/bin/
chmod +x /usr/local/bin/pipework

2 配置网桥连接

2.1 安装工具

yum install bridge-utils.x86_64 -y

2.2 修改网卡配置，实现桥接

给宿主机创建网桥

[root@docker-136 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33 
DEVICE=ens33
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
BROADCAST=192.168.0.255 #（前三位要和主机的ip地址一致，后一位为255）
DNS1=114.114.114.114
IPADDR=192.168.0.136 #（虚拟机的IP地址，前三位与主机的一致）
NETMASK=255.255.255.0
GATEWAY=192.168.0.1 #（主机的默认网关地址）
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=yes
BRIDGE=br0  #增加这个

设置物理网卡桥接到网桥

[root@docker-136 ~]# cat /etc/sysconfig/network-scripts/ifcfg-br0 
TYPE=Bridge
BOOTPROTO=static
NAME=br0
DEVICE=br0
ONBOOT=yes
IPADDR=192.168.0.136
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=114.114.114.114

重启网络

systemctl restart network

3 运行容器

[root@docker-136 ~]# pipework br0 $(docker run -d -it -p 80:80  --name http-199 httpd:2.2) 192.168.0.199/24@192.168.0.1
WARNING: IPv4 forwarding is disabled. Networking will not work.
[root@docker-136 ~]# ping 192.168.0.199

<html><body><h1>It works!</h1></body></html>[root@docker-136 ~]# 
[root@docker-136 ~]#

4 重启容器需要重新指定IP

[root@docker-136 ~]# docker stop 30a129173f2d
30a129173f2d
[root@docker-136 ~]# docker start 30a129173f2d
30a129173f2d
[root@docker-136 ~]# curl 192.168.0.199          
^C
[root@docker-136 ~]# ping 192.168.0.199
