CentOS 6.6和7.1 Docker自制CentOS鏡像docker
安裝:shell
1
|
yum -y
install
febootstrap
|
添加用戶:bootstrap
1
|
adduser admin
|
把admin用戶加到docker組:ubuntu
1
|
usermod
-a -G docker admin
|
使用admin用戶操做centos

2
|
su
admin
cd
/home/admin
|
使用root帳號製做鏡像,普通用戶製做後會有各類問題:bash
1
|
febootstrap -i
bash
-i wget -i yum -i iputils -i iproute centos66 centos66-doc http:
//mirrors
.163.com
/centos/6
.6
/os/x86_64/
|
(-i 安裝package, centos66 操做系統版本,centos66-doc安裝目錄,最後是源地址)ssh
上面成功後:測試
1
2
|
cd
centos66-doc/
tar
-c .|docker
import
- centos66-
bash
|
(centos66-bash爲docker鏡像名字)centos7
執行:spa

測試docker鏡像,建立一個容器:
1
|
docker run -t -i centos66-
bash
/bin/bash
|
退出後

ps

啓動剛纔建立的容器:
1
|
docker start 80548eb4275a
|
進入啓動後的容器:
1
|
docker attach 80548eb4275a
|
一個簡單的鏡像就製做完成了。
導出鏡像和導入鏡像方便分享鏡像文件
導出鏡像:
1
|
docker save IMAGENAME |
bzip2
-9 -c>img.
tar
.bz2
|
導入鏡像(換一臺機器):
1
|
bzip2
-d -c <img.
tar
.bz2 | docker load
|
