Ubuntu Docker安装及用户分组授权与Docker hub账号使用

来源：互联网发布：英语听力复读软件编辑：程序博客网时间：2024/05/28 03:01

我之前用的boot2docker镜像快速实现的Linux轻量提供，现在在Ubuntu上安装docker，网络采用NAT模式（个人比较习惯用此方式，桥接的方式比较麻烦，很多apt安装失败）。有时在Ubuntu安装docker需要耐心，安装过程会比较慢，安装完成后要将Linux用户加到docker用户分组才能正常使用docker命令。

Ubuntu安装Docker

命令：sudo apt-get install -y docker.io

Docker为当前用户授权

命令：$sudo gpasswd -a ${USER} docker

boonya@ubuntu:/usr/local/docker$ sudo gpasswd -a root  dockerAdding user root to group docker

注意：授权后需要重启系统reboot。

若不进行授权，使用docker的其他命令会报如下错误：

boonya@ubuntu:/usr/local/docker$ docker imagesFATA[0000] Get http:///var/run/docker.sock/v1.18/images/json: dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?

查看Docker的版本

命令：docker -v | docker --version

root@ubuntu:/home/boonya# docker --versionDocker version 1.6.2, build 7c8fca2root@ubuntu:/home/boonya#

查看Docker进程

命令：ps -ef | grep docker

root@ubuntu:/home/boonya# ps -ef | grep dockerroot       588     1  0 17:13 ?        00:00:20 /usr/bin/docker -d -H fd://root@ubuntu:/home/boonya#

Docker对容器的启动停止和重启操作

启动已被停止的容器container

命令：docker start container

停止运行中的容器container

命令：docker stop container

重启容器container

命令：docker restart container

Docker Hub账号注册

https://hub.docker.com/

Docker Hub命令行常用操作

登出

命令：docker logout

root@ubuntu:/home/boonya# docker logoutRemove login credentials for https://index.docker.io/v1/root@ubuntu:/home/boonya#

Push镜像到仓库

命令： docker push id/tag

注意：id必须是注册的账号名称，tag为你的镜像名。
