什么是docker

docker中的容器：

lxc --> libcontainer --> runC

OCI&OCF

OCI

Open Container-initiative

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
包含两个规格

运行时规范(runtime-spec)

形象规范(image-spec)

OCF

打开容器格式

runC是一个CLI工具，用于根据OCI规范生成和运行容器

容器作为runC的子进程启动，可以嵌入到各种其他系统中，而不需要运行守护进程

runC是基于libcontainer构建的，同样的容器技术为数百万的Docker引擎安装提供了动力

docker提供了一个专门容纳容器镜像的站点：https://hub.docker.com

docker架构

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。

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

当你使用docker时，你正在创建和使用镜像、容器、网络、卷、插件和其他对象。

镜像
映像是一个只读模板，它带有创建docker容器的指令。
通常，一个映像基于另一个映像，并具有一些额外的自定义。
您可以创建自己的映像，也可以只使用其他人创建并在注册表中发布的映像。
容器
容器是映像的可运行实例。
您可以通过docker API或CLI创建、运行、停止、移动或删除容器。
您可以将容器连接到一个或多个网络，将存储连接到它，甚至根据它的当前状态创建一个新映像。

安装及使用docker

docker安装

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# curl -o docker-ce.repo https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo% Total    % Received % Xferd  Average Speed   Time    Time     Time  CurrentDload  Upload   Total   Spent    Left  Speed

[root@localhost ~]# yum makecache[root@localhost ~]# yum -y install docker-ce

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
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）

[root@localhost ~]# systemctl enable --now docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

}//重启生效
