开发离不开项目的部署，运维，因此为了以后的开发便利，我最近学习了下服务的自运维，现在总结一下

技术
Jenkins+docker+git+Gitee 部署SpringBoot项目
环境
- Win10
- 虚拟机：VMware
- 系统：centos7
操作流程
1.安装虚拟机，配置centos系统，联通网络
2.配置Java环境
3.下载，安装，配置jenkins
1）Jenkins的介绍
Jenkins是一个广泛用于持续构建的可视化web工具，可用于自动化与构建、测试、交付或部署软件相关的各种任务。
2）看下Jenkins的工作流程
- 我们在本地开发项目。记得加上dcoker的依赖和Dockerfile的配置（后面说）。然后通过本地git提交到码云（Github）。
- 这时码云上的项目中配置钩子程序（Webhooks）。当我们在本地push的时候触发钩子。
这个URL的地址要触发Jenkis(后面介绍)

- Jenkins接收到通知以后，会调用虚拟机上的git。将远程码云仓库的项目pull到服务器上
- 接下来的工作中心就在Jenkins上。根据配置（后面详细说），将项目用服务器上mvn打成jar包
- 利用docker结合项目的dockerfile，打包成docker镜像，然后启动即可。（具体配置看后面）
3）Jenkins的下载和安装
看参考即可
不同的是我没有安装到tomcat下面，随tomcat启动，而是直接安装linux中，然后设置启动
这可以百度下
4.配置docker
- 首先是插件的安装，可以看参考，会遇到无法连接到外网服务器的问题，百度解决即可
- 进去后，首先全局配置，-》看参考 配置maven、JDK、Docker、git
这些都需要安装到服务器上，git还需生成私钥，公钥。公钥放到码云远程仓库，私钥放到Jenkins上，使得通过Jenkin利用git将代码拉到服务器上。
- 安装docker
- Springboot项目

docker依赖
<!-- Docker maven plugin start -->
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.13</version>
<configuration>
<imageName>${project.artifactId}</imageName><!--[a-z 0-9] 不然docker:build会报错-->
<dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
<!--dockerfile的地址-->
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
<!-- Docker maven plugin end -->
Dockerfile内容：
FROM hub.c.163.com/dwyane/openjdk:8
VOLUME /tmp
ADD docker-test-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
EXPOSE 8081
dockerfile的jar包的名字要和项目的名字保持一致
<groupId>com.wuhen</groupId>
<artifactId>docker-test</artifactId>
<version>0.0.1-SNAPSHOT</version>
然后上传到自己的码云远程仓库
5.使用Jenkins部署项目到docker
看参考
其中
第一次执行shell 添加shell：
#!/bin/bash -il
mvn docker:build
echo "当前docker 镜像："
docker images | grep docker-test
echo "启动容器----->"
docker run --name dockertest -p 8081:8081 -d docker-test
echo "启动服务成功！"
项目构建成功后再次构建shell有所改变
#!/bin/bash -il
# 先删除之前的容器
echo "remobe old container"
docker ps -a | grep dockertest | awk '{print $1}'| xargs docker rm -f
# 删除之前的镜像
echo "romove old image"
docker rmi docker-test
# 构建镜像
mvn docker:build
# 打印当前镜像
echo "current docker images"
docker images | grep docker-test
# 启动容器
echo "start container"
docker run --name dockertest -p 8081:8081 -d docker-test
# 打印当前容器
echo "current container"
docker ps -a | grep dockertest
echo "star service success!"
这个容器端口映射：项目的启动端口好为8081，映射到外部服务器端口为8081（可以固定。也可以随机），所以在外部浏览器访问IP：8081,即映射到项目上，添加路径即可访问

可以结合参考和我的文章选择自己合适的配置路线，与其说是写总结，也是结合自己弟参考文章的补充
