推荐答案

在Win10上尝试使用Docker构建或提取映像时，我遇到了相同的问题。将Docker vEthernet（DockerNAT）网络适配器的DNS更改为 8.8.8.8 的DNS对其进行了修复，如此。

I was facing the same issue when trying to build or pull an image with Docker on Win10. Changing the DNS of the Docker vEthernet(DockerNAT) network adapter to 8.8.8.8 fixed it for me, as described in this GitHub issue.

要更改DNS，请转到 Docker（TrayIcon）-> 设置-> 资源-> 网络并进行设置一个固定DNS服务器 ip = 8.8.8.8 。

To change the DNS go to Docker (TrayIcon) -> Settings -> Resources -> Network and set a fixed DNS server ip = 8.8.8.8.

将DNS服务器更改为

重启后，Docker能够再次拉出并构建映像。

After restarting Docker is able to pull and build images again.
