Docker 无法在 Windows 上启动

Question

在 Windows 上执行 docker version 命令返回以下结果：

 C:\Projects> docker version
Client:
 Version:      1.13.0-dev
 API version:  1.25
 Go version:   go1.7.3
 Git commit:   d8d3314
 Built:        Tue Nov  1 03:05:34 2016
 OS/Arch:      windows/amd64
error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.25/version: 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.

运行诊断会产生以下结果：

该错误与该部分有关：

在 Windows 上的默认守护程序配置中，docker 客户端必须运行提升才能连接

• 首先，验证 Docker Desktop 应用程序正在运行。如果没有，请启动它：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 守护程序类型，如下所述：

使用 Powershell ：

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

或者，使用 cmd ：

1. 以管理员身份 打开cmd
2. 启动命令： "C:\Program Files\Docker\Docker\DockerCli.exe" -SwitchDaemon
