ubuntu – 尝试连接到Docker守护程序套接字时权限被拒绝

在Ubuntu 16.04 LTS上,每当尝试使用docker login命令时,将显示以下交战消息：

docker login
Warning: failed to get default registry endpoint from daemon (Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.30/info: dial unix /var/run/docker.sock: connect: permission denied). Using system default: https://index.docker.io/v1/
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID,head over to https://hub.docker.com to create one.

有解决方案吗

使用sudo docker登录

或者@Serey提到将您的用户添加到docker组

usermod -aG docker $USER

从你的会话中断开！
