=================================================================================================================================
在正式开始之前，可以先去看看这个【使用docker-compose构建 wordpress+mysql】（https://www.cnblogs.com/52fhy/p/5991344.html）
参考：docker三剑客compose 【https://www.imooc.com/article/34135】有比较详细的命令解析和docker-compose.yml属性解析
=================================================================================================================================
好啦开始吧
=================================================================================================================================
一.简介docker三剑客
docker-machine
docker技术是基于Linux内核的cgroup技术实现的，那么问题来了，在非Linux平台上是否就不能使用docker技术了呢？答案是可以的，不过显然需要借助虚拟机去模拟出Linux环境来。
docker-machine就是docker公司官方提出的，用于在各种平台上快速创建具有docker服务的虚拟机的技术，甚至可以通过指定driver来定制虚拟机的实现原理（一般是virtualbox）。
docker-compose
docker镜像在创建之后，往往需要自己手动pull来获取镜像，然后执行run命令来运行。当服务需要用到多种容器，容器之间又产生了各种依赖和连接的时候，部署一个服务的手动操作是令人感到十分厌烦的。
dcoker-compose技术，就是通过一个.yml配置文件，将所有的容器的部署方法、文件映射、容器连接等等一系列的配置写在一个配置文件里，最后只需要执行docker-compose up命令就会像执行脚本一样的去一个个安装容器并自动部署他们，极大的便利了复杂服务的部署。【服务编排工具】
docker-swarm
swarm是基于docker平台实现的集群技术，他可以通过几条简单的指令快速的创建一个docker集群，接着在集群的共享网络上部署应用，最终实现分布式的服务。
相比起zookeeper等集群管理框架来说，swarm显得十分轻量，作为一个工具，它把节点的加入、管理、发现等复杂的操作都浓缩为几句简单的命令，并且具有自动发现节点和调度的算法，还支持自定制。虽然swarm技术现在还不是非常成熟，但其威力已经可见一般。
二.使用docker-compose安装spring boot服务容器+mysql容器，实现自动部署
==============================================================基础概念 ==============================================================
工程、服务、容器
-
Docker Compose 将所管理的容器分为三层，分别是工程（project）、服务（service）、容器（container）
-
Docker Compose 运行目录下的所有文件（docker-compose.yml）组成一个工程,一个工程包含多个服务，每个服务中定义了容器运行的镜像、参数、依赖，一个服务可包括多个容器实例
》在本例子中，整个的docker-compose.yml文件中的services共同组成了一个大的工程。
》这个工程，目前包含了两个服务，spring boot服务【服务名：swapping】 mysql服务【服务名：mysql】
》其中每个服务都可以同时启动多个容器实例。
===================================================================== ==============================================================
1.创建一个空目录
创建一个空目录的原因是，可以将
【docker-compose.yml或者docker-compose.yaml文件】
【构建spring boot容器的Dockerfile文件】
【spring boot的jar包】
放在同一个目录下。
mkdir swapping-docker-compose
本命令创建了一个目录【swapping-docker-compose】
cd swapping-docker-compose/
本命令进入本目录下
2.创建构建spring boot容器的Dockerfile文件
使用vi命令，创建文件名为【Dockerfile-swapping】的文件【名字自定义，只需要在docker-compose.yml中指定正确就可以】
vi Dockerfile-swapping
复制一下文本到本文件中【关于Dockerfile文件内容解释：https://www.cnblogs.com/sxdcgaq8080/p/10057088.html】
FROM java:8
VOLUME /temp
ADD swapping.jar swapping.jar
RUN bash -c 'touch /swapping.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","-Xmx1024m","-Xms1024m","/swapping.jar"]
3.创建docker-compose.yml文件，用于构建本组工程中各个参与服务的镜像【名词最上面有解释】
使用vi命令创建docker-compose.yml文件【文件名特定，也可以创建docker-compose.yaml文件，但也是特定名称，不能自定义】
vi docker-compose.yml
复制一下内容到文本中【文本内容解释在这个地方：https://www.cnblogs.com/sxdcgaq8080/p/10072040.html】【处理时区问题也在这个地方】
version : '3'
services:
swapping:
container_name: swapping-compose
build:
context: .
dockerfile: Dockerfile-swapping
ports:
- "9666:9666"
volumes:
- .:/vol/development
depends_on:
- mysql
links:
- "mysql:mysql"
restart: always
networks:
- my-network
environment:
- TZ=Asia/Shanghai
mysql:
container_name: mysql-compose
image: mysql:5.7
ports:
- "33061:3306"
command: [
'--character-set-server=utf8mb4',
'--collation-server=utf8mb4_unicode_ci',
'--default-time-zone=+8:00'
]
environment:
MYSQL_DATABASE: swapping
MYSQL_ROOT_PASSWORD: 398023
MYSQL_ROOT_HOST: '%'
restart: always
networks:
- my-network
networks:
my-network:
4.打包jar包，上传spring boot服务的jar包
打包操作参考https://www.cnblogs.com/sxdcgaq8080/p/10057088.html
注意数据库连接配置【是指定了具体的ip的，而没有用docker-compose.yml文件中配置的数据库服务名 mysql，因为出错连接不上https://www.cnblogs.com/sxdcgaq8080/p/10070740.html】
spring.datasource.url=jdbc:mysql://192.168.92.130:33061/swapping?useSSL=false&useUnicode=true&characterEncoding=UTF-8
打包以后使用rz命令上传jar包【rz命令不能使用的解决方法：https://www.cnblogs.com/sxdcgaq8080/p/10059141.html】
rz
上传以后，jar包 Dockerfile文件 docker-compose.yml文件位于同一个目录下
5.使用docker-compose命令构建并启动容器
使用命令 构建并启动本工程中的各个服务的容器
docker-compose up -d
-d代表在后台启动
也可以不加，这样启动日志就会当即打印出来
从下面的打印可以看到，初次构建并启动容器的时候，会有下面红框部分出现，也就是构建spring boot服务的镜像的过程。
注意：如果这个镜像你一直不删除，那就一直存在，并且在下次重新启动的时候，还是会用之前构建的这个镜像。
这也就意味着，如果你的spring boot服务中代码更新了，即时你重新打包上传到服务器上，如果你没有删除之前的镜像，那就算重启服务，依旧还是老的代码，使用的旧的镜像！！！！
因为docker-compose up命令会在没有镜像的时候去构建镜像，如果有，就会用旧的镜像，然后直接启动容器！！！
所以，千万注意重新部署的话，需要删除旧的镜像！！
此刻看到两个服务的容器都 done了，可以使用命令查看启动日志
docker-compose logs
本命令会展示本工程下所有服务容器的启动日志

而如果你只想查看工程中某个服务的容器的启动日志，可以指定服务名进行查看【注意是服务名，不是容器名称】
docker-compose logs swapping
注意： 是服务名swapping，而不是容器名swapping-compose。
因为容器名称是你自己指定的，如果你没有指定，那么容器的名称是你当前docker-compose.yml所在目录的名字+服务名字+_1生成的
6.启动服务后，测试访问使用
访问spring boot服务所在IP的地址+端口，访问服务：
http://192.168.92.130:9666/huayang
数据库存储正常
同时可以看到mysql数据库的数据集设置正确
7.停止本工程中所有服务，并移除容器，切记，如果代码更新，需要同时移除镜像再进行重新构建并启动容器的步骤
如果仅需要停止本工程，可以使用一下的1. 2. 3. 步的命令。
如果是因为spring boot代码更新，需要提供新的功能，那不仅需要1. 2. 3.步去停止容器实例运行，移除容器实例。还需要4.5.步查看并删除开始根据yml文件配置构建的镜像，才能重新构建镜像，否则下次启动依旧使用的旧镜像，你新的代码不会起作用！

最后附录上，关于docker-compose命令的详解和docker-compose.yml文件的属性详解【https://www.cnblogs.com/sxdcgaq8080/p/10072040.html】！！
====================================================================================================================
遗留问题，如果使用docker-compose启动服务，每个服务有多实例，怎么解决端口冲突的问题？
docker-compose scale mysql=2 swapping=3
docker-compose scale 服务名=个数 服务名=个数
这里只是去掉yml配置文件中指定容器名称的属性，解决容器名称重复的问题，那么端口问题怎么解决呢？？
container_name: swapping-compose
待解决！！！！！！！！！
