0.11.1版本docker安装与使用
关于什么是docker，请参考http://baike.baidu.com/view/11854949.htm?fr=aladdin 我的服务器是ubuntu server 12.04，硬件是dell R420 一、安装 1、安装源 1 2 3 apt-keyadv--keyserverhkp: //keyserver .ubuntu.com:80--recv-keys36A1D7869245C8950F966E92D8576A8BA88D21E9 sh-c "echodebhttps://get.docker.io/ubuntudockermain>/etc/apt/sources.list.d/docker.list" apt-getupdate 2、安装docker 1 apt-get install lxc-docker 3、下载tar包并加入镜像里 一般下载镜像的时候，都是先docker search image_name，然后docker pullimage_name 但由于最近GFW屏蔽了网络，在现在的时候会出现以下错误，根本pull不了镜像。 1 2 Pullingrepositorycentos 2014 /05/19 13:35:11Gethttps: //cdn-registry-1 .docker.io /v1/repositories/library/centos/tags : read tcp162.159.253.251:443:connectiontimedout 所以为了解决此问题，我就从别的地方下载了打包好的tar（后边会解释然后自己打包的），然后使用docker load导入 先下载（有centos与ubuntu） 1 2 wgethttp: //docker .widuu.com /centos . tar wgethttp: //docker .widuu.com /ubuntu . tar 加入到镜像里 1 2 dockerload-icentos. tar dockerload-iubuntu. tar 查看镜像列表 1 2 3 4 5 6 root@ip-10-10-25-218:~ /docker/images #dockerload-icentos.tar root@ip-10-10-25-218:~ /docker/images #dockerload-iubuntu.tar root@ip-10-10-25-218:~ /docker/images #dockerimages REPOSITORYTAGIMAGEIDCREATEDVIRTUALSIZE <none><none>607347d2a9463monthsago300.2MB ubuntu /widuu latest963b9d0e10ba3monthsago155MB 给centos的改个名 1 2 3 4 5 root@ip-10-10-25-218:~ /docker/images #dockertag607centos:latest root@ip-10-10-25-218:~ /docker/images #dockerimages REPOSITORYTAGIMAGEIDCREATEDVIRTUALSIZE centoslatest607347d2a9463monthsago300.2MB ubuntu /widuu latest963b9d0e10ba3monthsago155MB 测试镜像是否可用 1 2 3 4 5 6 7 8 9 root@ip-10-10-25-218:~ /docker/images #dockerimages REPOSITORYTAGIMAGEIDCREATEDVIRTUALSIZE centoslatest607347d2a9463monthsago300.2MB ubuntu /widuu latest963b9d0e10ba3monthsago155MB root@ip-10-10-25-218:~ /docker/images #dockerruncentos/bin/echo"hello,i'mcentossystem" hello,i'mcentossystem root@ip-10-10-25-218:~ /docker/images #dockerrunubuntu/widuu/bin/echo"hello,i'mubuntusystem" hello,i'mubuntusystem root@ip-10-10-25-218:~ /docker/images #
