01.课程简介

掌握docker核心功能：

1.Docker命令

2.Docker存储

3.Docker网络

4.Docker Compose

5.Dockerfile

一键批量启动：MySQL、Redis、RabbitMQ、Zookeeper、OpenSearch、Kafka、Nacos、Prometheus、Grafana

02.基础 - 为什么有Docker

为什么使用docker? 代码写好后，安装中间件安装不成功......
生产环境软件和操作系统不兼容问题

docker可以跨平台安装软件、中间件

解决生产、准生产、测试、开发环境不同的问题

交付客户按照安装文档操作过于繁琐

传给客户通过优盘、网盘、传输助手等不同版本管理麻烦，传输过于频繁

拥有一款类似手机应用商店的技术，想使用可以去应用商店下载、安装，比如微信，抖音

github相当于手机的应用商店

github地址：https://github.com/

注：如果访问 Github 网站超时，可以 点击此链接地址 解决
加速构建、分享、运行应用

构建：快速把应用进行打包

分享：把软件包快速发布到GitHub应用商店中

运行：一行命令启动应用

03.基础 - Docker架构与容器化

1.客户端发送命令 docker pull redis 到服务端，Docker Daemon 先检查本地是否有redis镜像，有提示本地存在不下载，没有则去Registry镜像仓库（默认是国外官网，可以配置成国内仓库）拉取最新版本的redis到本地(实线——>)

2.客户端发送命令 docker run redis 到服务端，Docker Daemon 根据本地镜像 Images(若本地没有,先去仓库下载到本地) 启动容器 Containers( -- -->)

3.客户端发送命令 docker build xxx 到服务端，Docker Daemon 构建生成镜像，存放到本地(- - - - ->)

4.客户端发送命令 docker push xxx 到服务端，Docker Daemon 把本地构建或存放的镜像推送到远程 Registry镜像仓库，其他人可以根据需要下载此镜像（........>）

build（构建）：使用 docker build

share（分享）：使用 docker push、docker pull

run（运行）：使用 docker run

核心：镜像(类似软件包)、容器(类似基于软件包启动的应用)

服务器：服务间不隔离，其中一个应用发生内存泄漏，就造成服务器“炸了”

虚拟机：应用间隔离，一个虚拟机发生内存泄漏，只造成虚拟机“炸了”，不会影响服务器上的其他虚拟机，每个虚拟机必须有完整的操作系统，笨重臃肿

容器：在容器运行时上隔离，每个容器是一个应用，容器发生内存泄漏，只造成容器“炸了”，不影响其他容器，作用在底层的操作系统，可根据容器自己需要加入可执行的文件和库

容器类似轻量级的Vm(虚拟机)
容器共享操作系统内核
容器拥有自己的文件系统、CPU、内存、进程空间等
容器互相隔离

特点：轻量、快速（秒级启动）、隔离、跨平台、高密度

04.基础 - 购买云服务器

云服务器 -> 安装Docker

1.登录、2.控制台、3.产品页、4.云服务器、立即选购、自定义配置、

设置密码：MAjunnan6666^

05.基础 - 停机不收费

微信扫码，点击确认此操作

注意：公网IP关机后会释放，下次登录需要重新复制新的公网IP

再次开机，可以重新使用原服务器资源

06.基础 - 安装Docker

07.命令 - 镜像操作

实验：启动一个nginx，并将它的首页改为自己的页面，发布出去，让所有人都能使用

下载镜像 -> 启动容器 -> 修改页面 -> 保存镜像 -> 分享社区

镜像检索： docker search

下载：docker pull

列表：docker images

删除：docker rmi

[root@VM-0-16-centos ~]# docker search nginx
镜像名 描述信息 收藏数 是否官方
# 下载镜像，不添加版本号，默认下载最新版
