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

设置启动参数
# centos 在/etc/sysconfig/docker
# 其他操作系统请前往下面的网址
# https:
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:
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
1
1
进去docker查看IP
docker
attach centos06
ifconfig
service sshd restart

123
docker开机启动脚本
vi docker_start
.sh

1
#! /bin/bash
service docker start
docker start centos06
docker start centos07
pipework br0 centos06
132.97.

pipework br0 centos07
132.97.

docker
exec -i centos06 service sshd restart
docker
exec -i centos07 service sshd restart

1、将脚本移动到/etc/rc
.d/init
.d目录下
mv /home/xy/docker_start
.sh /etc/rc
.d/init
.d
2、增加脚本的可执行权限
chmod +
x /etc/rc
.d/init
.d/docker_start
.sh
3、添加脚本到开机自动启动项目中
cd /etc/rc
.d/init
.d
chkconfig --
add docker_start
.sh
chkconfig docker_start
.sh on
