## Java微服务篇5——Docker ##

### 1、虚拟化技术 ###

虚拟化技术是一种计算机资源管理技术，是将计算机的各种实体资源，如服务器、网络、内存及存储 等，予以抽象、转换后呈现出来。虚拟化技术打破了计算机实体结构间的，不可切割的障碍。使用户可 以比原本的组态更好的方式，来应用这些资源

*  高性能的物理硬件产能过剩和老的旧的硬件产能过低的重组重用，透明化底层物理硬件
 *  软件跨环境迁移问题(代码的水土不服)

### 2、Docker简介 ###

“Docker is the world’s leading software container platform.“，Docker的定位是一 个应用容器平台

Docker 可以让开发者打包他们的应用，以及依赖包到一个轻量级、可移植的容器中，然后发布到任何 流行的 Linux 机器上。Docker容器是完全使用沙箱机制，相互隔离，性能开销也极低，通俗的讲是服务器中高性能的虚拟机，可以将一台物理机虚拟N多台虚拟机的机器，互相之间隔离，互不影响

**特点**

*  标准化交付：Docker将应用打包成标准化单元，用于交付、部署
 *  轻量级：容器及包含了软件运行所需的所有环境，而且非常轻量级
 *  高可靠：容器化的应用程序，可以在任何Linux环境中始终如一的运行
 *  隔离性：容器化的应用程序，具备隔离性，这样多团队可以共享同一Linux系统资源

**容器与虚拟机得对比**

### 3、Docker基本概念 ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2d5ZmdoaA_size_16_color_FFFFFF_t_70 2]

*  宿主机：安装Docker守护进程的Linux服务器，称之为宿主机
 *  镜像（Image）：Docker 镜像，就相当于是一个 root 文件系统。除了提供容器运行时所需的程序、 库、资源、配置等文件外，还包含了一些为运行时准备的一些配置参数
 *  容器（Container）：镜像运行之后的实体，镜像和容器的关系，就像是面向对象程序设计中的类和对 象一样，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
 *  仓库（Repository）：仓库可看成一个镜像控制中心，用来保存镜像

### 4、Docker安装 ###

移除之前版本的依赖

yum remove docker \
            docker-client \
            docker-client-latest \
            docker-common \
            docker-latest \
            docker-latest-logrotate \
            docker-logrotate \
            docker-engine

安装依赖库

yum install -y yum-utils

设置镜像

# 国外
    yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
    # 国内
    yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新软件包索引

yum makecache fast

安装docker

yum install docker-ce docker-ce-cli containerd.io

测试

[root@VM-8-13-centos ~]# docker -v
    Docker version 20.10.8, build 3967b7d

启动docker

systemctl start docker

**docker卸载**

卸载docker

yum remove docker-ce docker-ce-cli containerd.io

删除镜像

rm -rf /var/lib/dockerrm -rf /var/lib/containerd

**阿里云镜像加速（如果感觉下载镜像慢，添加一下镜像加速）**

[root@VM-8-13-centos ~]# mkdir -p /etc/docker
    [root@VM-8-13-centos ~]# tee /etc/docker/daemon.json <<-'EOF'
    > {

    > }
    > EOF
    {
        
      "registry-mirrors": ["https://12sotewv.mirror.aliyuncs.com"]
    }
    [root@VM-8-13-centos ~]# systemctl daemon-reload
    [root@VM-8-13-centos ~]# systemctl restart docker

### 6、数据卷 ###

当删除容器时，容器里的数据也随之丢失，但有时候希望数据持久化（同步到本地）

第一个连接

[root@VM-8-13-centos ~]# docker run -it --name Vcentos -v /home/Vcentos:/home centos
    [root@3e48cef6a24f /]# ls
    bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
    [root@3e48cef6a24f /]# cd /home
    [root@3e48cef6a24f home]# ls
    [root@3e48cef6a24f home]# echo > centos.txt << eof
    > hello,centos!
    > eof

第二个连接

[root@VM-8-13-centos ~]# cd /home/
    [root@VM-8-13-centos home]# ls
    lighthouse  Vcentos
    [root@VM-8-13-centos home]# cd Vcentos/
    [root@VM-8-13-centos Vcentos]# ls
    centos.txt

容器会直接操作宿主机得文件，删除容器数据也不会丢失

#### 6.1、使用数据卷将mysql数据放在宿主机 ####

[root@VM-8-13-centos ~]# docker run -id --name Vmysql -e MYSQL_ROOT_PASSWORD=123456 -p 3366:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql mysql:5.7
    dbc17238076b1ad37fa885bfb922b9ca2fa045eea046265060d3d1bc5f63c07a

#### 6.2、匿名挂载、具名挂载 ####

匿名挂载（在-v只写了容器内的路径，没有写容器外的路径）

docker run -id -p 3344:80 -v /ect/nginx nginx
    # 查看对应的随机挂载目录 docker volumes ls
    # 默认挂载路径为/var/lib/docker/volumes/xxx/_data

具名挂载

docker run -id -p 3344:80 -v nginx-config: /etc/nginx nginx
    # 默认挂载路径为/var/lib/docker/volumes/nginx-config/_data

#### 6.3、数据卷容器 ####

多个容器数据互通

第一个连接

[root@VM-8-13-centos ~]# docker run -id --name centos1 -v /home/contos-data:/home centos 
    c648a76683917ecaf5787588a17264f14f9902c86f73ceec2c6ec42e4ca41b97

### 7、DockerFile ###

构建自己的镜像

#### 7.1、DockerFile指令（关键词） ####

*  FROM：基础镜像
 *  MAINTAINER：作者
 *  RUN：镜像执行时需要执行的命令
 *  ADD：添加文件
 *  WORKDRIR：工作目录
 *  VOLUMES：挂载卷
 *  EXPOSE：暴露端口
 *  CMD：指定这个镜像运行要运行的命令（只有最后一个会生效）
 *  ENV：构建的时候设置环境变量

#### 7.2、构建自己的centos ####
