我的情况是,我在WSL shell中运行docker命令,仍然能够做到这一点,而在git-bash(或另一个基于windows的shell)我面临这个错误。

对我来说,解决方案是这个答案,但重新启动窗口

其他回答

The same issue arrived when I started with the docker in windows 10. I was able to run docker --version successfully but failed when I tried to run docker pull docker/whalesay. I tried many things suggested in the answers over here but my issue was resolved when I followed the below steps: 1 . Search for docker in windows and run docker desktop as administrator. 2 . Check the bottom-left docker symbol it should be green if the docker is running. 3 . If it's not running first install "wsl_update". 4 . Open the docker desktop and sign in with your docker credentials, when you are logged in you can see the server restarting and the bottom left logo turns green. 5. To check whether docker is running or not open PowerShell as administrator and run docker run hello-world.

我最近也有同样的问题。问题是安全软件(趋势科技)阻止docker创建Hyperv网络接口。你也应该检查防火墙,反病毒软件没有阻止安装或配置。

对我来说,解决方案是这个答案,但重新启动窗口

这是最终的解决方案。这对我很有用!!

1)在你的系统托盘中找到鲸鱼,然后右键单击

2)进入“设置”>重置

3)恢复出厂设置

在安装了带有WSL 2后端运行的Docker Desktop 4.7.1后,我在终端上也遇到了同样的问题。托盘鲸的图标也没有显示。

在我的情况下,问题是我之前已经安装了一个WSL发行版(Ubuntu),它已经是默认的。带有WSL 2后端的Docker Desktop安装了自己的发行版Docker - Desktop。并且它必须是默认的(至少在没有在其他地方配置的情况下)。

所以我不得不在PowerShell中运行这个命令:wsl——setdefault docker-desktop并重新启动docker服务。在这里找到了解决方案。
