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

其他回答

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。

对我来说,这个问题通过在Docker Desktop中唱歌解决了。

我也遇到过同样的问题,可能是管理员的问题,所以按照下面的步骤来安装docker

windows10

.

Download docker desktop from docker hub after login to docker.Docker Desktop Installer.exe file will be downloaded. Install Docker Desktop Installer.exeusing Run as administrator -> Mark windows container during installation else it will only install linux container. It will ask for Logout after logging out and login it shows docker desktop in menu. After install, go to -> computer management -> Local users and groups -> Groups -> docker-user -> Add user in members Run docker desktop using Run as administrator Check docker whale icon in Notification tab run command >docker version Successfully using docker without any issue.

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

首先,我下载了windows 10的docker, OS Built 19042和版本20H2,如这个视频所示, 但我的docker还在起步阶段。我用提供的命令运行docker,但我得到了这样一个 连接时错误:Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version: open //。/pipe/docker_engine:系统找不到文件

然后,这些解决方案为我启动docker工作:

以管理员身份打开Powershell & 运行这个命令:'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon

OR

以管理员身份打开cmd & 运行命令:"C:\Program Files\Docker\Docker\DockerCli.exe

我在这里找到了这个。希望这对你也有帮助!
