window安装docker 先决条件：
1、Windows 10 操作系统为专业版、企业版、教育版及部分家庭版！
2、开启server：CMD命令运行：services.msc，找的Server并启动。
3、安装及开启Hyper-V：控制面板--程序--启用或关闭Windows功能--勾选Hyper-V
Hyper-V 是微软开发的虚拟机，类似于 VMWare 或 VirtualBox，仅适用于 Windows 10。这是 Docker Desktop for Windows 所使用的虚拟机。但是，这个虚拟机一旦启用，QEMU、VirtualBox 或 VMWare Workstation 15 及以下版本将无法使用！如果你必须在电脑上使用其他虚拟机（例如开发 Android 应用必须使用的模拟器），请不要使用 Hyper-V！
4、将我们的CPU虚拟化设置为启动状态

如果不是启用状态，启动电脑进入BIOS，(电脑开机后一直按F1，不同电脑不一样)

安装遇到的问题及解决办法
1、安装最新版本的docker（4.4.3.0）后，打开Docker Desktop提示：A JavaScript error occurred in the main process，百度搜了一些解决方案，最后还是未解决，所以后来就安装了低版本的docker。
参考解决方案：

2、安装低版本的docker（3.0.4.51218）
在历史版本里面找到该版本并下载：https://docs.docker.com/desktop/windows/release-notes/3.x/
安装后Docker Desktop可以正常打开，但用命令行进行测试时报错：
PS C:\Users> docker run -d -p 80:80 docker/getting-started
docker: error during connect: In the default daemon configuration on Windows, the docker client must be run with elevated privileges to connect.: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/create: open //./pipe/docker_engine: The system cannot find the file specified.
解决办法：
在cmd命令运行下面的脚本：
cd "C:\Program Files\Docker\Docker"
DockerCli.exe -SwitchDaemon
再次运行就可以正常运行了：
PS C:\Users> docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
3a78847ea829: Pull complete 052260bdedd9: Pull complete 47a64f8bebcb: Pull complete Digest: sha256:975f4b14f326b05db86e16de00144f9c12257553bba9484fed41f9b6f2257800
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(windows-amd64, nanoserver-1809)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run a Windows Server container with:
PS C:\> docker run -it mcr.microsoft.com/windows/servercore:ltsc2019 powershell
