当我尝试通过Powershell中的docker pull alpine:latest命令提取docker映像时，收到此消息
Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on [::1]:53: read udp [::1]:43738->[::1]:53: read: connection refused
我为docker使用 linux容器，这是我的 docker信息

经过研究，我发现重新启动docker / 更改dns 将解决此问题。我确实重新启动了docker +重新安装了边缘版本+更改了dns，但对我而言不起作用。
几周前，我还已经将docker诊断数据上传到 docker for windows github存储库，但是没有运气。
如果我将docker切换为 windows容器，则docker pull命令可以完美地提取图像。当我切换回 linux容器时，它不起作用。
