Docker 实质上是在已经运行的 Linux 下制造了一个隔离的文件环境，因此它执行的效率几乎等同于所部署的 Linux 主机。
因此，Docker 必须部署在 Linux 内核的系统上。如果其他系统想部署 Docker 就必须安装一个虚拟 Linux 环境。
Windows Docker 安装
Docker Desktop 是 Docker 在 Windows 10 和 macOS 操作系统上的官方安装方式，这个方法依然属于先在虚拟机中安装 Linux 然后再安装 Docker 的方法。
注意：此方法仅适用于 Windows 10 操作系统专业版、企业版、教育版和部分家庭版！

D:\hexoBlog>Docker 镜像加速
配置阿里云加速
检查加速器是否生效
检查加速器是否生效配置加速器之后，如果拉取镜像仍然十分缓慢，请手动检查加速器配置是否生效，在命令行执行 docker info，如果从结果中看到了如下内容，说明配置成功。

D:\hexoBlog>docker run hello-world
C:\Users\wang>docker run hello-world
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.
(amd64)
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 an Ubuntu container with:
$ docker run -it ubuntu bash

C:\Users\wang>要是看到上面的示例 那就说明 你的Docker部署及运行成功了。
windows10安装Hyper-V
最近需要在windows10上安装Docker Desktop，然而docker Desktop依赖于Hyper-V。自己的电脑上控制面板功能里没有Hyper-V。这里记录一下解决方案。
复制以下代码，然后另存为do.cmd。在文件上右键，以管理员的身份运行。
pushd "%~dp0"
dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum >hyper-v.txt
for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
del hyper-v.txt
Dism /online /enable-feature /featurename:Microsoft-Hyper-V-All /LimitAccess /ALL执行的时间有点长，循环出现很多遍，等到执行完毕时，输入Y，重启电脑。
然后打开控制面板，就可以看到已经出现结果了
