1、修改宿主机IP地址,建立桥接网口
root@ubuntu:~# more /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto br0
iface br0 inet static
address 192.168.88.71
netmask 255.255.255.0
network 192.168.88.0
broadcast 192.168.88.255
bridge_ports p2p1
bridge_stp off
gateway 192.168.88.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 114.114.114.114
2、启动时使用br0
root@ubuntu:~# more /etc/default/docker
DOCKER_OPTS="--insecure-registry 192.168.88.66:5000 -b=br0"
3、添加静态IP地址
root@ubuntu:~# more manual_con_static_ip.sh
#/bin/bash
if [ -z $1 ] || [ -z $2 ] || [ -z $3 ] || [ -z $4 ] || [ -z $5 ];
then
echo "*****Input the necessary parameters: CONTAINERID IP MASK GATEWAY ETHNAME"
echo "*****Call the script like: sh manual_con_static_ip.sh b0e18b6a4432 192.168.88.70 24 192.168.88.1 eth1"
exit
fi
#判断宿主机网卡是否存在
ifconfig $ETHNAME > /dev/null 2>&1
if [ $? -eq 0 ]; then
read -p "$ETHNAME exist,do you want delelte it? y/n " del
if [[ $del == 'y' ]]; then
ip link del $ETHNAME
else
exit
fi
fi
#
pid=`docker inspect -f '{{.State.Pid}}' $CONTAINERID`
mkdir -p /var/run/netns
find -L /var/run/netns -type l -delete
if [ -f /var/run/netns/$pid ]; then
rm -f /var/run/netns/$pid
fi
ln -s /proc/$pid/ns/net /var/run/netns/$pid
#
ip link add $ETHNAME type veth peer name B
brctl addif br0 $ETHNAME
ip link set $ETHNAME up
ip link set B netns $pid
#先删除容器内已存在的eth0
ip netns exec $pid ip link del eth0 > /dev/null 2>&1
#设置容器新的网卡eth0
ip netns exec $pid ip link set dev B name eth0
ip netns exec $pid ip link set eth0 up
ip netns exec $pid ip addr add $SETIP/$SETMASK dev eth0
ip netns exec $pid ip route add default via $GATEWAY
