当前回答

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。

我的一个朋友也有类似的问题,我们尝试了一下,效果很好。

Hyper-V,尽管在“打开或关闭Windows功能”中被列为活动,但实际上并不是活动的。当在PowerShell下运行systeminfo时,这变得很明显,并且看到 要求被列出为满足(这不是您期望的Hyper-V实际运行的输出)。步骤:

打开“打开或关闭Windows功能” 如果您不确定如何做到这一点,请参考 https://www.howtogeek.com/250228/what-windows-10s-optional-features-do-and-how-to- [turn-them-on-or-off /] [1] 关闭Hyper-V(取消复选框,确保所有子组件都被标记为关闭) 点击“Ok”-你的机器将重新启动。 当你的电脑再次启动时,打开“打开或关闭Windows功能”,然后重新打开Hyper-V。您的机器将重新启动。

现在你可以通过运行docker hello-world image进行测试。

我也有同样的问题。

启动docker守护进程解决了这个问题。只需搜索docker,按下windows键,然后点击“docker Dekstop”。Daemon应该马上就能运行了。

启动Docker Desktop后,确保左下角的Docker守护进程状态为绿色,并在鼠标悬停在其上时显示为RUNNING。

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。

在Windows 10机器上安装: 在安装搜索Windows功能之前,请先搜索并检查Windows hypervisor平台和Linux子系统

WSL 1或WSL 2的安装是强制性的,所以在docker提示您安装时安装它。

你需要从windows商店安装ubantu(版本16,18或20):

uhelp版本20

安装完成后,可以运行docker -version等命令 或docker在Linux终端运行hello-world。

您可以运行“C:\Program Files\Docker\Docker\DockerCli.exe”-SwitchDaemon并将Docker CLI指向Linux或Windows容器。这对我很管用。
