Docker:尝试连接时发生错误 [英] Docker: An error occurred trying to connect

问题描述

在 Windows 上安装了 Docker，另外安装了 2 个，Oracle VM VirualBox 和 Kitematic.我在我的 Windows 10 PC 中禁用了 Hyper-V.现在的问题是我无法从 DockerHub 下载任何 Docker 镜像，甚至无法运行命令

Installed Docker on Windows with 2 additional installs, Oracle VM VirualBox and Kitematic. I've disabled Hyper-V in my Windows 10 PC. Now the problem is I can't download any Docker images from DockerHub, not even I can run the command as

Docker info

在两端显示以下错误.

尝试连接时发生错误:获取http://localhost:2375/v1.21/info:拨打tcp 127.0.0.1:2375:ConnectExtcp:由于目标机器主动，无法建立连接拒绝了.

An error occurred trying to connect: Get http://localhost:2375/v1.21/info: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it.

如果我在 Docker QuickStart Terminal 中运行它，它可以工作，但不能在 PowerShell 或 MSBuild 中工作.

If I run it in Docker QuickStart Terminal it works, but not working in PowerShell or in MSBuild.

推荐答案

如果您使用的是 windows 命令提示符而不是 Docker QuickStart Terminal，请参阅 official docs 您应该执行以下步骤(假设您的 docker 机器的名称为 default):

If you are using windows command prompt instead of Docker QuickStart Terminal see official docs you should make following steps (assuming your docker machine has the name default):

1. docker-machine start default 或者新建一个
2. docker-machine ls会显示你的机器正在运行

3. docker-machine env --shell cmd default 你会看到类似

1. docker-machine start default or create new one
2. docker-machine lswill show you your machine running

3. docker-machine env --shell cmd default and you'll see something like

SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://192.168.99.100:2376
SET DOCKER_CERT_PATH=C:UsersArseny.dockermachinemachinesdefault
SET DOCKER_MACHINE_NAME=default
REM Run this command to configure your shell:
REM     FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO %i

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