在Ubuntu中，安装完Docker后，当我们执行docker相关的命令时，会遇到如下提示信息：

$ docker psGot permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json: dial unix /var/run/docker.sock: connect: permission denied

这是因为Docker进程使用 Unix Socket 而不是 TCP 端口。而默认情况下，Unix socket 属于 root 用户，因此需要 root权限 才能访问。详情如下：

Manage Docker as a non-root userThe 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 only access it using sudo. The docker daemon always runs as the root user.If you don't want 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.

解决办法：

将用户添加到docker组中，

sudo groupadd dockersudo gpasswd -a ${USER} dockersudo newgrp docker

到此，相信大家对"如何设置Docker"有了更深的了解，不妨来实际操作一番吧！这里是网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
