在Windows上执行docker version命令返回的结果如下:

C:\Projects> docker version

运行诊断将产生以下结果:

错误与这部分有关:

在Windows上的默认守护进程配置中,docker客户端必须 被提升运行连接

首先,验证Docker Desktop应用程序正在运行。如果没有,启动它:这将运行docker守护进程(只需等待几分钟)。 然后,如果错误仍然存在,您可以尝试切换Docker守护进程类型,如下所示:

Powershell:

以管理员身份打开Powershell 启动命令:& 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon .exe

或者,使用cmd:

以管理员身份打开cmd 启动命令:“C:\Program Files\Docker\Docker\DockerCli.exe”-SwitchDaemon

其他回答

对我来说,这个错误是通过停止在Hyper-V中运行的虚拟Ubuntu实例来解决的:

系统无法找到指定的文件。在Windows上的默认守护进程配置中,docker客户端必须以提升方式运行才能连接。此错误也可能表明docker守护进程没有运行。

一旦Ubuntu实例停止,Docker Desktop重新启动,我通常使用的Docker命令就可以正常运行了。

PS:我之所以有这个想法是因为Docker Desktop已经编译了一个错误日志,并提供了作为用户反馈发送到Docker Hub…日志似乎表明我的机器内存不足,Docker失败的原因很简单。杀死Ubuntu实例解决了这个问题。

我知道这个问题是很久以前的问题了,但我没有找到合适的解释和解决方案,所以希望我的答案是有用的:)

假设你在Windows上安装了Docker工具箱,Docker和Docker -machine命令都是可用的。通常,人们在使用这两种方法时都会感到困惑。

docker命令仅在虚拟机中用于管理映像。docker-machine命令用于在主机上管理Linux虚拟机。

所以,请在您的Windows机器上使用docker-machine命令。在虚拟机内部使用docker命令。要使用docker命令,例如docker ps,您可以打开docker快速启动终端,或者在cmd/bash/PowerShell上运行这些命令:

docker-machine run default /假设default是你的Linux虚拟机/

Docker-machine SSH默认

这将启动boot2docker,您将在命令行上看到docker图标。然后可以使用docker命令。

祝你好运。

对于win10,我有同样的问题:

error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.39/images/load?quiet=0: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

docker服务似乎正常工作。重启也无济于事。 以管理员身份从安装目录运行二进制文件会有所帮助。

在我的例子中:

run as administrator -> C:\Program Files\Docker\Docker\Docker for Windows.exe

我正在使用窗口10,并执行以下步骤来解决此问题。

check虚拟化从任务管理器启用——>性能 重新启动docker服务 安装最新的docker版本并重新启动计算机。 确保docker服务正在运行。

以上步骤帮助我解决了这个问题。

在powershell或Git bash中打开C驱动器并运行以下命令

.\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon
