在centos7上安裝docker
- 查看docker的版本
[root@docker2 ~]# yum list| grep docker
docker.x86_64 2:1.12.6-68.gitec8512b.el7.centos
docker-client.x86_64 2:1.12.6-68.gitec8512b.el7.centos
docker-common.x86_64 2:1.12.6-68.gitec8512b.el7.centos
......
docker版本為1.12.6
- 安裝docker
yum install -y docker - 網(wǎng)絡(luò)配置
見CentOS7.2網(wǎng)絡(luò)配置
CentOS7下Docker橋接網(wǎng)絡(luò)配置
物理機(jī)的IP信息
網(wǎng)卡eth0的ip：
192.168.175.211
要橋接的網(wǎng)卡br0的ip：192.168.175.88
網(wǎng)關(guān)：192.168.175.2
配置橋接網(wǎng)絡(luò)
停止docker服務(wù)
service docker stop刪除docker0網(wǎng)卡
ip link set dev docker0 down
brctl delbr docker0
如果沒有bctl命令螺垢，需要安裝yum install -y bridge-utils新建橋接網(wǎng)卡br0
brctl addbr br0
ip link set dev br0 up
ip addr add 192.168.175.88/24 dev br0為br0分配物理網(wǎng)絡(luò)中的ip地址
ip addr del 192.168.175.211/24 dev eth0#將宿主機(jī)網(wǎng)卡的IP刪除（到這一步會(huì)斷網(wǎng)）
brctl addif br0 eth0#將宿主機(jī)網(wǎng)卡掛到br0上
ip route del default#刪除原路由
route -n
ip route add default via 192.168.175.2 dev br0#為br0設(shè)置路由-
到這里可以用
192.168.175.88連接主機(jī)
配置docker
配置橋接網(wǎng)絡(luò)
vim /etc/sysconfig/docker-network，其他系統(tǒng)可能在/etc/sysconfig/docker下哦。
在DOCKER_NETWORK_OPTIONS添加-b=br0戏挡，如下：
DOCKER_NETWORK_OPTIONS="-b=br0"配置加速器
vi /etc/docker/daemon.json
{
"registry-mirrors": ["你的加速器地址"]
}
啟動(dòng)docker
service docker start安裝pipework
git clone https://github.com/jpetazzo/pipework
如果沒有g(shù)it掷倔，請先安裝git：yum -y install git
- 將pipework拷貝到系統(tǒng)運(yùn)行目錄下
cp ~/pipework/pipework /usr/local/bin/
啟動(dòng)容器并設(shè)置網(wǎng)絡(luò)
docker run -itd --net=none --name=cs7.01 centos:latest /bin/bash#創(chuàng)建并啟動(dòng)容器耍缴，給容器命名為cs7.01
pipework br0 cs7.01 192.168.175.89/24@192.168.175.88進(jìn)入容器查看ip
docker attach cs7.01
