什么是docker
docker中的容器：docker是一个管理容器的工具，程序。
lxc --> libcontainer --> runC
OCI
Open Container-initiative：开放的容器规范
- 由Linux基金会主导于2015年6月创立
- 旨在围绕容器格式和运行时制定一个开放的工业化标准
- contains two specifications
- the Runtime Specification（runtime-spec） 运行时的规范
- the Image Specification（image-spec） 镜像的规范
OCF
Open Container Format ：开放的容器格式
runC is a CLI tool for spawning and running containers according to the OCI specification
- Containers are started as a child process of runC and can be embedded into various other systems without having to run a daemon
- runC is built on libcontainer, the same container technology powering millions of Docker Engine installations
docker提供了一个专门容纳容器镜像的站点：https://hub.docker.com
runC是一个命令行工具包，用来创建和运行容器，根据OCI的标准。
包含以下两点：
1） 容器启动成runC的子进程，可以嵌入到其他各种系统中，而不需要运行守护进程
2） runC构建在libcontainer之上，同样的容器技术支撑着数以百万计的Docker Engine安装
docker提供了一个专门容纳容器镜像的站点：https://hub.docker.com
docker架构
容器的服务需要设置开机自启，不然下次重启以后开机客户端访问服务端，服务端没启动，docker命令都是用不了
docker -ee:企业版（收费的，还禁止亚洲人使用）
docker-ce:社区版 （开源的，我们学习使用的都是这个版本）
docker镜像与镜像仓库
为什么镜像仓库名字是Registry而不是repository？在docker中仓库的名字是以应用的名称取名的。
Registry类似于是一个仓库的管理员，repository是存放镜像的仓库，每一个仓库存放着某一种镜像的各个版本，根据用户按需索取。
镜像是静态的，而容器是动态的，容器有其生命周期，镜像与容器的关系类似于程序与进程的关系。镜像类似于文件系统中的程序文件，而容器则类似于将一个程序运行起来的状态，也即进程。所以容器是可以删除的，容器被删除后其镜像是不会被删除的。
docker对象
When you use docker, you are creating and using images, containers, networks, volumes, pluginns, and other objects.
- IMAGES
- An image is a read-only template with instructions for creating a docker container.
- Often, an image is based on another image, with some additional customization.
- You might create your own images or you might only use those created by others and published in a registry.
- CONTAINERS
- A conntainer is a runnable instance of an image.
- You can create, run, stop, move, or delete a container using the docker API or CLI.
- You can connect a container to one or more networks, attach storage to it, or even create a new image based on its current state.
当你使用docker时，你是在创建和使用镜像、容器、网络、卷、插件和其他对象。
镜像
镜像是一个只读模板，带有创建docker容器的说明。
通常，一个镜像基于另一个镜像，并带有一些额外的定制。
您可以创建自己的镜像，也可以只使用其他人创建并在注册表中发布的镜像。
容器
容器是运行中的镜像。
您可以使用docker API或CLI（敲命令）创建、运行、停止、移动或删除容器。
您可以将一个容器连接到一个或多个网络，将存储附加到它，甚至根据它的当前状态创建一个新镜像。
安装及使用docker
docker安装

docker加速
docker-ce的配置文件是/etc/docker/daemon.json，此文件默认不存在，需要我们手动创建并进行配置，而docker的加速就是通过配置此文件来实现的。
docker的加速有多种方式：
- docker cn（docker中国）
- 中国科技大学加速器
- 阿里云加速器（需要通过阿里云开发者平台注册帐号，免费使用个人私有的加速器） 我配置的aliyun加速器地址：www.aliyun.com
1 [root@localhost ~]# systemctl enable --now docker
2 Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.设为开机自启，立马启动，目录就创建出来了
3 [root@localhost ~]# ls /etc/docker
4 key.json 目录有了
5 [root@localhost ~]# systemctl status docker 查看状态
6 [root@localhost ~]# cd /etc/docker/
7 [root@localhost docker]# ls
8 key.json
9 [root@localhost docker]# vi daemon.json 用vi编辑器打开此文件配置
