Ubuntu 非root用户使用Docker命令提示:connect: permission denied

打开终端直接输入 docker 命令时出现以下错误: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http:///var/run/docker.sock/v1.40/images/json: dial unix /var/run/docker.sock: connect: permission denied 解决办法: 将非root用户加入docker组 usermod -aG docker yourUser
