docker.sock 尝试从未知位置运行

docker.sock 尝试从未知位置运行

在我的 ubuntu 22 docker 容器上安装 docker 桌面后，权限问题变得非常严重。我不知道如何解决这个问题，所以我卸载了 docker-desktop 应用程序和 docker 本身。现在，当我只安装 docker 时，我无法运行任何构建。似乎 docker 想要在unix:///home/{user}/.docker/desktop/docker.sock.

我不知道为什么，总是从/var/run/docker.sock

这是一个完整的错误： Cannot connect to the Docker daemon at unix:///home/kramar/.docker/desktop/docker.sock. Is the docker daemon running

和/lib/systemd/system/docker.socket

我在 docker 版本 20 中遇到了同样的问题

卸载 docker Desktop 后。

跑步

  1. docker context ls
  2. docker context use default
  3. 如果需要，重新启动docker服务。

在 中~/.docker，我删除了上下文和桌面目录，但即使您不这样做，上述步骤仍然有效。
