引言
现在的java开发人员真的是太难了，之前需要学习前端做全栈，如今还需要会架构和懂些运维的知识了，也就是DevOps(开发及运维)，引用B站狂神老师说的一句话就是只要学不死，就往死里学！！！现在给大家分享下从狂神老师那里学来的Docker中的知识梳理（学习阶段我是在windows上面操作的）。
为什么学Docker
Docker与传统虚拟机有什么不同：
1.传统虚拟机需要虚拟出一整个操作系统，而Docker是直接运行在宿主机上的。
2.Docker的每个容器中都有自己的文件系统，互不影响。
Docker的优点
1.应用更快的交付和部署
2.更便捷的升级和扩缩容
3.更简单的系统运维
4.更高效的计算资源利用
Docker相关名词
1.镜像（Image）：Docker 镜像（Image），就相当于是一个 root 文件系统。比如官方镜像 ubuntu:16.04 就包含了完整的一套 Ubuntu16.04 最小系统的 root 文件系统。
2.容器（Container）：镜像（Image）和容器（Container）的关系，就像是面向对象程序设计中的类和实例一样，镜像是静态的定义，容器是镜像运行时的实体。容器可以被创建、启动、停止、删除、暂停等。
3.仓库（Repository）：仓库可看成一个代码控制中心，用来保存镜像。
Docker安装
1.进入Docker官网https://docs.docker.com/
2.点击Download and install
3.侧边栏找到Get Docker,然后我这边选择的Windows版本的
4.下载Docker Desktop Installer.exe
配置阿里云镜像加速
由于Docker下载镜像默认是在国外比较慢，所以我们可以配置阿里云镜像加快下载速度，这点就跟Maven差不多。https://xxxxxx.mirror.aliyuncs.com这个需要换成自己的地址。获取方式https://blog.csdn.net/sinat_32247833/article/details/79767263
{"debug": true,"experimental": false,"registry-mirrors": ["https://xxxxxx.mirror.aliyuncs.com","http://hub-mirror.c.163.com"]
}
Docker的基本命令
