docker run -itd --net=none --name=centos07 --cpuset-cpus="0-3" -m 1024M --memory-reservation 1024M centos6-132.97.8.7-170106_2 /bin/bash

DOCKER_STORAGE_OPTIONS="--storage-opt dm.loopdatasize=2000G --storage-opt dm.loopmetadatasize=10G --storage-opt dm.fs=ext4 --storage-opt dm.basesize=20G" #dm.loopdatasize=2000G是指存放数据的数据库空间为2t，默认是100g #dm.loopmetadatasize=10G是存放Metadata数据空间为10g，默认是2g #dm.fs=ext4是指容器磁盘分区为ext4 #dm.basesize=20G是指容器根分区默认为20g，默认是10g
linux桥接网络配置

[root@localhost ~]# cd /etc/sysconfig/network-scripts/

[root@localhost network-scripts]# cp ifcfg-eth0 ifcfg-br0

[root@localhost network-scripts]# vi ifcfg-eth0

//改成这样

DEVICE=eth0

HWADDR=00:0C:29:06:A2:35

TYPE=Ethernet

UUID=34b706cc-aa46-4be3-91fc-d1f48c301f23

ONBOOT=yes

BRIDGE=br0

NM_CONTROLLED=yes

BOOTPROTO=static

[root@localhost network-scripts]# vi ifcfg-br0

//改成这样

DEVICE=br0

TYPE=Bridge

ONBOOT=yes

BOOTPROTO=static

IPADDR=192.168.216.131

NETMASK=255.255.255.0

GATEWAY=192.168.216.2

DNS=8.8.8.8

# https://docs.docker.com/installation/#installation vi /etc/sysconfig/docker #在OPTIONS=--selinux-enabled这行中修改为OPTIONS=--selinux-enabled -b=br0即让docker服务启动时使用br0网卡进行桥接
安装pipework

git clone https://github.com/jpetazzo/pipework

cp ~/pipework/pipework /usr/local/bin/

启动手动设置网络的容器

docker run -itd --net=none --name=centos06 --cpuset-cpus="0-3" -m 1024M --memory-reservation 1024M ssh-centos6 /bin/bash

使用pipework设置IP

pipework br0 centos06 132.97.8.6/24@132.97.8.1

进去docker查看IP

docker attach centos06

ifconfig

service sshd restart #重启ssh

pipework br0 centos06 132.97.8.6/24@132.97.8.1 pipework br0 centos07 132.97.8.7/24@132.97.8.1 docker exec -i centos06 service sshd restart docker exec -i centos07 service sshd restart
