在Windows上执行docker version命令返回的结果如下:

当前回答

尝试从提升的命令提示符运行以下命令:

SET DOCKER_CERT_PATH=C:\Users\[YourName]\.docker\machine\machines\default
SET DOCKER_HOST=tcp://[yourDockerDeamonIp]:2376
SET DOCKER_MACHINE_NAME=default
SET DOCKER_TLS_VERIFY=1
SET DOCKER_TOOLBOX_INSTALL_PATH=C:\Program Files\Docker Toolbox

您可能还会发现,即使不设置这些env变量,从docker快速启动终端运行命令也没有问题。

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

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。

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。

如果你用的是Windows,试试这个

 docker-machine env --shell cmd default 
 @FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO @%i

进行测试

docker run hello-world

确保你有Hyper-V启用,这是我的情况下的问题。
