Docker中使用固定IP
1. 安装
下载pipework工具, 然后配置到path路径.
$ git clone https://github.com/jpetazzo/pipework.git
$ sudo cp -rp pipework/pipework /usr/local/bin/
$ sudo yum -y install apring bridge-utils
2. 网络设定
# 删除容器之后删除网络
ip link set br0 down
brctl delbr br0
# 创建网络
brctl addbr br0;
ip link set dev br0 up;
ip addr add 192.168.2.1/24 dev br0;
docker stop db;
docker start db;
pipework br0 db 192.168.2.103/24;
3. 创建容器和设定IP
docker run -d -e SERVERADMIN=”mail@domain.com” -e DEFAULT_LOGS_DIR=”/logs/httpd/defaults” –name=apache -v /home/pandy/docker-resources/apache/conf:/etc/httpd/conf -v /home/pandy/docker-resources/apache/html:/var/www/html pandy/apache
pipework br0 apache 192.168.2.100/24;
方法二: Docker中使用固定IP: http://yaxin-cn.github.io/Docker/docker-container-use-static-IP.html
注意:重启电脑之后ip依然改变
创建容器
docker run -i -t –rm –net=’none’ –name test centos:centos7 /bin/bash
container id =>b3ae71122656
docker inspect -f “{{.State.Pid}}” b3ae71122656 //这个容器id对应的pid
输出:8948 , 注意, 记住这个符号
创建一个链接, 打开另一个终端, 输入
sudo mkdir -p /var/run/netns
sudo ln -s /proc/8948/ns/net /var/run/netns/8948
然后创建一对端到端的网卡，将veth_db84e747c3绑定到docker0网桥，并启动。将另一块网卡X放到container内部
sudo ip link add veth_db84e747c3 type veth peer name X
sudo brctl addif docker0 veth_db84e747c3
sudo ip link set veth_db84e747c3 up
sudo ip link set X netns 8948
在docker容器里面查看:ip addr
[root@b3ae71122656 /]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
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
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
6: X: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether c6:d8:5f:f6:fa:6a brd ff:ff:ff:ff:ff:ff
然后对container内部新添加的网卡进行配置（可以通过man ip-netns更详细查看）
sudo ip netns exec 8948 ip link set dev X name eth0 //重新命名容器内部的网卡叫eth0
sudo ip netns exec 8948 ip link set eth0 up
sudo ip netns exec 8948 ip addr add 172.17.111.10/16 dev eth0 //配置网卡
sudo ip netns exec 8948 ip route add default via 172.17.42.1
测试:
ping 172.17.111.10
