docker.sock权限被拒绝 [英] docker.sock permission denied

问题描述

当我尝试运行简单的docker命令，例如:

When I try to run simple docker commands like:

$ docker ps -a

我收到一条错误消息:

获得权限被拒绝.../var/run/docker.sock:连接:权限被拒绝

Got permission denied ... /var/run/docker.sock: connect: permission denied

当我检查权限时

$ ls -al /var/run/

我看到这一行:

srw-rw---- root docker docker.sock

因此，我遵循许多论坛的建议，并将本地用户添加到docker组:

So, I follow an advice from many forums and add local user to docker group:

$ sudo usermod -aG docker $USER

但这无济于事.我仍然收到非常相同的错误消息.我该如何解决?

But it does not help. I still get the very same error message. How can I fix it?

推荐答案

对于那些不熟悉shell的人，命令:

For those new to the shell, the command:

$ sudo usermod -aG docker $USER

需要在shell中定义$USER.默认情况下，该位置通常位于此位置，但是在某些外壳中，您可能需要将该值设置为登录ID.

needs to have $USER defined in your shell. This is often there by default, but you may need to set the value to your login id in some shells.

更改用户组不会更改用户已打开的现有登录名，终端和外壳程序.为避免再次执行登录，您只需运行:

Changing the groups of a user does not change existing logins, terminals, and shells that a user has open. To avoid performing a login again, you can simply run:

$ newgrp docker

获得对当前shell中该组的访问权限.

to get access to that group in your current shell.

完成此操作后，用户将在服务器上有效地具有root用户访问权限，因此仅对受不受限制的sudo访问权限信任的用户执行此操作.

Once you have done this, the user effectively has root access on the server, so only do this for users that are trusted with unrestricted sudo access.
