Linux 下非root用户使用docker

通常我们使用linux系统的时候,最好是不要直接使用root账号,但是使用Docker的时候,默认又是不能使用非root用户的,关于原因,官方说法如下:

The docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can access it with sudo. For this reason, docker daemon always runs as the root user.
To avoid having to use sudo when you use the docker command, create a Unix group called docker and add users to it. When the docker daemon starts, it makes the ownership of the Unix socket read/writable by the docker group.

下面是让非root用户可用root的步骤:

1

创建docker组

sudo groupadd docker

2

将当前用户加入docker组

sudo gpasswd -a ${USER} docker

3

重新启动docker服务(下面是CentOS7的命令)

sudo systemctl restart docker

4

当前用户退出系统重新登陆

5

运行docker命令,测试

docker ps
