docker 是什么？
Docker是基于Go语言实现的云开源项目。
Docker的主要目标是“Build，Ship and Run Any App,Anywhere”，也就是通过对应用组件的封装、分发、部署、运行等生命周期的管理，使用户的APP（可以是一个WEB应用或数据库应用等等）及其运行环境能够做到“一次镜像，处处运行”。
Linux容器技术的出现就解决了这样一个问题，而 Docker 就是在它的基础上发展过来的。将应用打成镜像，通过镜像成为运行在Docker容器上面的实例，而 Docker容器在任何操作系统上都是一致的，这就实现了跨平台、跨服务器。只需要一次配置好环境，换到别的机器上就可以一键部署好，大大简化了操作。
容器和虚拟机比较
虚拟机
虚拟机（virtual machine）就是带环境安装的一种解决方案。
它可以在一种操作系统里面运行另一种操作系统，比如在Windows10系统里面运行Linux系统CentOS7。应用程序对此毫无感知，因为虚拟机看上去跟真实系统一模一样，而对于底层系统来说，虚拟机就是一个普通文件，不需要了就删掉，对其他部分毫无影响。这类虚拟机完美的运行了另一套系统，能够使应用程序，操作系统和硬件三者之间的逻辑不变。
虚拟机的缺点：
- 资源占用多
- 冗余步骤多
- 启动慢
容器
Linux容器(Linux Containers，缩写为 LXC)
Linux容器是与系统其他部分隔离开的一系列进程，从另一个镜像运行，并由该镜像提供支持进程所需的全部文件。容器提供的镜像包含了应用的所有依赖项，因而在从开发到测试再到生产的整个过程中，它都具有可移植性和一致性。
Linux 容器不是模拟一个完整的操作系统而是对进程进行隔离。有了容器，就可以将软件运行所需的所有资源打包到一个隔离的容器中。容器与虚拟机不同，不需要捆绑一整套操作系统，只需要软件工作所需的库资源和设置。系统因此而变得高效轻量并保证部署在任何环境中的软件都能始终如一地运行。
启动速度快，占用体积小
对比
-
传统虚拟机技术是虚拟出一套硬件后，在其上运行一个完整操作系统，在该系统上再运行所需应用进程；
-
容器内的应用进程直接运行于宿主的内核，容器内没有自己的内核且也没有进行硬件虚拟。因此容器要比传统虚拟机更为轻便。
-
每个容器之间互相隔离，每个容器有自己的文件系统 ，容器之间进程不会相互影响，能区分计算资源。
docker的特点
一次构建，随处运行
更快的应用交付和部署
传统的应用开发完成后，需要提供一堆安装程序和配置说明文档，安装部署后需根据配置文档进行繁杂的配置才能正常运行。Docker化之后只需要交付少量容器镜像文件，在正式生产环境加载镜像并运行即可，应用安装配置在镜像里已经内置好，大大节省部署配置和测试验证时间。
更便捷的升级和扩容和缩容
随着微服务架构和Docker的发展，大量的应用会通过微服务方式架构，应用的开发构建将变成搭乐高积木一样，每个Docker容器将变成一块“积木”，应用的升级将变得非常容易。当现有的容器不足以支撑业务处理时，可通过镜像运行新的容器进行快速扩容，使应用系统的扩容从原先的天级变成分钟级甚至秒级。
更简单的系统运维
应用容器化运行后，生产环境运行的应用可与开发、测试环境的应用高度一致，容器会将应用程序相关的环境和状态完全封装起来，不会因为底层基础架构和操作系统的不一致性给应用带来影响，产生新的BUG。当出现程序异常时，也可以通过测试环境的相同容器进行快速定位和修复。
更高效的计算资源利用
Docker是内核级虚拟化，其不像传统的虚拟化技术一样需要额外的Hypervisor支持，所以在一台物理机上可以运行很多个容器实例，可大大提升物理服务器的CPU和内存的利用率。
docker下载
docker官网：http://www.docker.com
设置镜像：
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
docker的组成
镜像
Docker 镜像（Image）就是一个只读的模板。镜像可以用来创建 Docker 容器，一个镜像可以创建很多容器。
它也相当于是一个root文件系统。比如官方镜像 centos:7 就包含了完整的一套 centos:7 最小系统的 root 文件系统。
相当于容器的“源代码”，docker镜像文件类似于Java的类模板，而docker容器实例类似于java中new出来的实例对象。
容器
- 从面向对象角度
Docker 利用容器（Container）独立运行的一个或一组应用，应用程序或服务运行在容器里面，容器就类似于一个虚拟化的运行环境，容器是用镜像创建的运行实例。就像是Java中的类和实例对象一样，镜像是静态的定义，容器是镜像运行时的实体。容器为镜像提供了一个标准的和隔离的运行环境，它可以被启动、开始、停止、删除。每个容器都是相互隔离的、保证安全的平台
- 从镜像容器角度
可以把容器看做是一个简易版的 Linux 环境（包括root用户权限、进程空间、用户空间和网络空间等）和运行在其中的应用程序。
仓库
仓库（Repository）是集中存放镜像文件的场所。
类似于
Maven仓库，存放各种jar包的地方；
github仓库，存放各种git项目的地方；
Docker公司提供的官方registry被称为Docker Hub，存放各种镜像模板的地方。
仓库分为公开仓库（Public）和私有仓库（Private）两种形式。
最大的公开仓库是 Docker Hub(https://hub.docker.com/)，
存放了数量庞大的镜像供用户下载。国内的公开仓库包括阿里云 、网易云等

启动守护式容器
命令：docker run -d 容器名
#使用镜像centos:latest以后台模式启动一个容器
docker run -d centos
问题：然后docker ps -a 进行查看, 会发现容器已经退出
很重要的要说明的一点: Docker容器后台运行,就必须有一个前台进程.
容器运行的命令如果不是那些一直挂起的命令（比如运行top，tail），就是会自动退出的。
这个是docker的机制问题,比如你的web容器,我们以nginx为例，正常情况下,
我们配置启动服务只需要启动响应的service即可。例如service nginx start
但是,这样做,nginx为后台进程模式运行,就导致docker前台没有运行的应用,
这样的容器后台启动后,会立即自杀因为他觉得他没事可做了.
所以，最佳的解决方案是,将你要运行的程序以前台进程的形式运行，
常见就是命令行模式，表示我还有交互操作，别中断

重新进入：
docker attach 容器ID
区别：
attach 直接进入容器启动命令的终端，不会启动新的进程，exit退出，会导致容器的停止。
exec 是在容器中打开新的终端，并且可以启动新的进程，exit退出，不会导致容器的停止。
从容器内拷贝文件到主机上
docker cp 容器ID:容器内路径 目的主机路径
export ：导出容器的内容留作为一个tar归档文件[对应import命令]
import ：从tar包中的内容创建一个新的文件系统再导入为镜像[对应export]

Docker 镜像
是什么？
是一种轻量级、可执行的独立软件包，它包含运行某个软件所需的所有内容，我们把应用程序和配置依赖打包好形成一个可交付的运行环境(包括代码、运行时需要的库、环境变量和配置文件等)，这个打包好的运行环境就是image镜像文件。
只有通过这个镜像文件才能生成Docker容器实例(类似Java中new出来一个对象)。
联合文件系统
UnionFS（联合文件系统）：Union文件系统（UnionFS）是一种分层、轻量级并且高性能的文件系统，它支持对文件系统的修改作为一次提交来一层层的叠加，同时可以将不同目录挂载到同一个虚拟文件系统下(unite several directories into a single virtual filesystem)。Union 文件系统是 Docker 镜像的基础。镜像可以通过分层来进行继承，基于基础镜像（没有父镜像），可以制作各种具体的应用镜像。
特性：一次同时加载多个文件系统，但从外面看起来，只能看到一个文件系统，联合加载会把各层文件系统叠加起来，这样最终的文件系统会包含所有底层的文件和目录
Docker镜像加载原理
docker的镜像实际上由一层一层的文件系统组成，这种层级的文件系统UnionFS。
bootfs(boot file system)主要包含bootloader和kernel, bootloader主要是引导加载kernel, Linux刚启动时会加载bootfs文件系统，在Docker镜像的最底层是引导文件系统bootfs。这一层与我们典型的Linux/Unix系统是一样的，包含boot加载器和内核。当boot加载完成之后整个内核就都在内存中了，此时内存的使用权已由bootfs转交给内核，此时系统也会卸载bootfs。
rootfs (root file system) ，在bootfs之上。包含的就是典型 Linux 系统中的 /dev, /proc, /bin, /etc 等标准目录和文件。rootfs就是各种不同的操作系统发行版，比如Ubuntu，Centos等等。
对于一个精简的OS，rootfs可以很小，只需要包括最基本的命令、工具和程序库就可以了，因为底层直接用Host的kernel，自己只需要提供 rootfs 就行了。由此可见对于不同的linux发行版, bootfs基本是一致的, rootfs会有差别, 因此不同的发行版可以公用bootfs。
镜像分层最大的一个好处就是共享资源，方便复制迁移，就是为了复用。
比如说有多个镜像都从相同的 base 镜像构建而来，那么 Docker Host 只需在磁盘上保存一份 base 镜像；
同时内存中也只需加载一份 base 镜像，就可以为所有容器服务了。而且镜像的每一层都可以被共享。
Docker镜像层都是只读的，容器层是可写的
当容器启动时，一个新的可写层被加载到镜像的顶部。
这一层通常被称作“容器层”，“容器层”之下的都叫“镜像层”。
当容器启动时，一个新的可写层被加载到镜像的顶部。这一层通常被称作“容器层”，“容器层”之下的都叫“镜像层”。
所有对容器的改动 - 无论添加、删除、还是修改文件都只会发生在容器层中。只有容器层是可写的，容器层下面的所有镜像层都是只读的。
docker commit
docker commit提交容器副本使之成为一个新的镜像

DockerFile
是什么？
Dockerfile是用来构建Docker镜像的文本文件，是由一条条构建镜像所需的指令和参数构成的脚本。
Dockerfile，需要定义一个Dockerfile，Dockerfile定义了进程需要的一切东西。Dockerfile涉及的内容包括执行代码或者是文件、环境变量、依赖包、运行时环境、动态链接库、操作系统的发行版、服务进程和内核进程(当应用进程需要和系统服务和内核进程打交道，这时需要考虑如何设计namespace的权限控制)等等;
构建过程
- 每条保留字指令都必须为大写字母且后面要跟随至少一个参数
- 指令按照从上到下，顺序执行
- #表示注释
- 每条指令都会创建一个新的镜像层并对镜像进行提交
- docker从基础镜像运行一个容器
- 执行一条指令并对容器作出修改
- 执行类似docker commit的操作提交一个新的镜像层
- docker再基于刚提交的镜像运行一个新容器
- 执行dockerfile中的下一条指令直到所有指令都执行完成
保留字
FROM
基础镜像，当前新镜像是基于哪个镜像的，指定一个已经存在的镜像作为模板，第一条必须是from
MAINTAINER
maintainer，镜像维护者的姓名和邮箱地址
RUN
容器构建时需要运行的命令
一共有两种模式：
- shell模式：RUN 命令
- exec模式：RUN[“可执行文件”,“参数1”,“参数2”…]
RUN在docker build时运行
EXPOSE
当前容器对外暴露出的端口
WORKDIR
指定在创建容器后，终端默认登陆的进来工作目录，一个落脚点
USER
指定该镜像以什么样的用户去执行，如果都不指定，默认是root
ENV
用来在构建镜像过程中设置环境变量
ENV 变量名 变量值
- 1
比如：
ENV JAVA_HOME /usr/test
- 1
ADD
将宿主机目录下的文件拷贝进镜像且会自动处理URL和解压tar压缩包
COPY
类似ADD，拷贝文件和目录到镜像中，但是不解压
COPY src dest
- 1
VOLUME
容器数据卷，用于数据保存和持久化工作
CMD
指定容器启动后的要干的事情
一共有两种模式：
- shell模式：RUN 命令
- exec模式：RUN[“可执行文件”,“参数1”,“参数2”…]
Dockerfile 中可以有多个 CMD 指令，但只有最后一个生效，CMD 会被 docker run 之后的参数替换
CMD是在docker run 时运行。
ENTRYPOINT
类似于 CMD 指令，但是ENTRYPOINT不会被docker run后面的命令覆盖，而且这些命令行参数会被当作参数送给 ENTRYPOINT 指令指定的程序
ENTRYPOINT可以和CMD一起用，一般是变参才会使用 CMD ，这里的 CMD 等于是在给 ENTRYPOINT 传参。
当指定了ENTRYPOINT后，CMD的含义就发生了变化，不再是直接运行其命令而是将CMD的内容作为参数传递给ENTRYPOINT指令，他两个组合会变成 ENTRYPOINT CMD
如果 Dockerfile 中如果存在多个 ENTRYPOINT 指令，仅最后一个生效。

网络模式
bridge
Docker 服务默认会创建一个 docker0 网桥，其上有一个 docker0 内部接口，该桥接网络的名称为docker0，它在内核层连通了其他的物理或虚拟网卡，这就将所有容器和本地主机都放到同一个物理网络。Docker 默认指定了 docker0 接口 的 IP 地址和子网掩码，让主机和容器之间可以通过网桥相互通信。
-
Docker使用Linux桥接，在宿主机虚拟一个Docker容器网桥(docker0)，Docker启动一个容器时会根据Docker网桥的网段分配给容器一个IP地址，称为Container-IP，同时Docker网桥是每个容器的默认网关。因为在同一宿主机内的容器都接入同一个网桥，这样容器之间就能够通过容器的Container-IP直接通信。
-
docker run 的时候，没有指定network的话默认使用的网桥模式就是bridge，使用的就是docker0。在宿主机ifconfig,就可以看到docker0和自己create的network(后面讲)eth0，eth1，eth2……代表网卡一，网卡二，网卡三……，lo代表127.0.0.1，即localhost，inet addr用来表示网卡的IP地址
-
网桥docker0创建一对对等虚拟设备接口一个叫veth，另一个叫eth0，成对匹配。
-
整个宿主机的网桥模式都是docker0，类似一个交换机有一堆接口，每个接口叫veth，在本地主机和容器内分别创建一个虚拟接口，并让他们彼此联通。这样一对接口叫veth pair
-
每个容器实例内部也有一块网卡，每个接口叫eth0
-
docker0上面的每个veth匹配某个容器实例内部的eth0，两两配对，一一匹配
-
host
host，直接使用宿主机的 IP 地址与外界进行通信，不再需要额外进行NAT 转换。
PS C:\Users\mao\Desktop> docker network inspect host [ { "Name": "host", "Id": "58028068163e97bb12cd7f24921cccfd49ca06286f756e82b34d7a73494a562b", "Created": "2022-05-02T11:06:10.406162704Z", "Scope": "local", "Driver": "host", "EnableIPv6": false, "IPAM": { "Driver": "default", "Options": null, "Config": [] }, "Internal": false, "Attachable": false, "Ingress": false, "ConfigFrom": { "Network": "" }, "ConfigOnly": false, "Containers": {}, "Options": {}, "Labels": {} } ] PS C:\Users\mao\Desktop>

none
在none模式下，并不为Docker容器进行任何网络配置。
也就是说，这个Docker容器没有网卡、IP、路由等信息，只有一个lo
需要我们自己为Docker容器添加网卡、配置IP等。
PS C:\Users\mao\Desktop> docker network inspect none [ { "Name": "none", "Id": "c0e15a3d224806a9b9df4a1558048e744ccd81dfb2b82d93ef82a0426997ae69", "Created": "2022-05-02T11:06:10.394932679Z", "Scope": "local", "Driver": "null", "EnableIPv6": false, "IPAM": { "Driver": "default", "Options": null, "Config": [] }, "Internal": false, "Attachable": false, "Ingress": false, "ConfigFrom": { "Network": "" }, "ConfigOnly": false, "Containers": {}, "Options": {}, "Labels": {} } ] PS C:\Users\mao\Desktop>

container
新建的容器和已经存在的一个容器共享一个网络ip配置而不是和宿主机共享。新创建的容器不会创建自己的网卡，配置自己的IP，而是和一个指定的容器共享IP、端口范围等。同样，两个容器除了网络方面，其他的如文件系统、进程列表等还是隔离的。
使用：
docker run -it --network container:被共享的容器名 ...
- 1
自定义网络
创建网络：
docker network create 网络名字
- 1
自定义网络本身就维护好了主机名和ip的对应关系（ip和域名都能通）
平台架构
Docker 是一个 C/S 模式的架构，后端是一个松耦合架构，众多模块各司其职。
Docker 运行的基本流程：
-
用户是使用 Docker Client 与 Docker Daemon 建立通信，并发送请求给后者。
-
Docker Daemon 作为 Docker 架构中的主体部分，首先提供 Docker Server 的功能使其可以接受 Docker Client 的请求。
-
Docker Engine 执行 Docker 内部的一系列工作，每一项工作都是以一个 Job 的形式的存在。
-
Job 的运行过程中，当需要容器镜像时，则从 Docker Registry 中下载镜像，并通过镜像管理驱动 Graph driver将下载镜像以Graph的形式存储。
-
当需要为 Docker 创建网络环境时，通过网络管理驱动 Network driver 创建并配置 Docker 容器网络环境。
-
当需要限制 Docker 容器运行资源或执行用户指令等操作时，则通过 Execdriver 来完成。
-
Libcontainer是一项独立的容器管理包，Network driver以及Exec driver都是通过Libcontainer来实现具体对容器进行的操作。
Docker-compose 容器编排
是什么？
Compose 是 Docker 公司推出的一个工具软件，可以管理多个 Docker 容器组成一个应用。你需要定义一个 YAML 格式的配置文件docker-compose.yml，写好多个容器之间的调用关系。然后，只要一个命令，就能同时启动/关闭这些容器
docker建议我们每一个容器中只运行一个服务,因为docker容器本身占用资源极少,所以最好是将每个服务单独的分割开来但是这样我们又面临了一个问题？
如果我需要同时部署好多个服务,难道要每个服务单独写Dockerfile然后在构建镜像,构建容器,这样累都累死了,所以docker官方给我们提供了docker-compose多服务部署的工具
例如要实现一个Web微服务项目，除了Web服务容器本身，往往还需要再加上后端的数据库mysql服务容器，redis服务器，注册中心eureka，甚至还包括负载均衡容器等等
Compose允许用户通过一个单独的docker-compose.yml模板文件（YAML 格式）来定义一组相关联的应用容器为一个项目（project）
可以很容易地用一个配置文件定义一个多容器的应用，然后使用一条指令安装这个应用的所有依赖，完成构建。Docker-Compose 解决了容器与容器之间如何管理编排的问题。

概念
-
一个文件：docker-compose.yml
-
服务：一个个应用容器实例，比如订单微服务、库存微服务、mysql容器、nginx容器或者redis容器
-
工程：由一组关联的应用容器组成的一个完整业务单元，在docker-compose.yml 文件中定义。
步骤
- 编写Dockerfile定义各个微服务应用并构建出对应的镜像文件
- 使用 docker-compose.yml定义一个完整业务单元，安排好整体应用中的各个容器服务。
- 最后，执行docker-compose up命令来启动并运行整个应用程序，完成一键部署上线

# VOLUME 指定临时文件目录为/tmp，在主机/var/lib/docker目录下创建了一个临时文件并链接到容器的/tmp
VOLUME /tmp
# 将jar包添加到容器中并更名为Docker_compose_boot.jar
ADD Docker_compose_boot-0.0.1-SNAPSHOT.jar Docker_compose_boot.jar
# 运行jar包
RUN bash -c 'touch Docker_compose_boot.jar'
ENTRYPOINT ["java","-jar","Docker_compose_boot.jar"]
