简介： 基于微服务的CICD实战

模块介绍

现有一个微服务项目，按照业务拆分为如下几个模块

book-web 前端，采用 Vue MVVM，服务端 Thymeleaf SSR 渲染，友好 SEO MPA。服务端路由，Spring MVC
book-gateway 微服务网关，Spring Cloud Gateway
book-service 接口提供方，Spring Cloud Alibaba Dubbo 服务消费方
book-server 数据承载方，Spring Cloud Alibaba Dubbo 服务提供方
book-common 实体，Dubbo 接口 jar
cloud-common 微服务公共 jar
common pom
school-parent 最上级父工程 pom

common 继承关系

在项目根路径下执行，Maven 命令，截取 2 段输出

mvn clean install -pl com.lab:book-common -am -Ptest

Alibaba Sentinel

nohup java -Dserver.port=8858 -Dsentinel.dashboard.auth.username=sentinel -Dsentinel.dashboard.auth.password=Aa123456 -jar sentinel-dashboard-1.7.2.jar >sentinel.log 2>&1 &

Maven 环境

root@jazz-pc:/opt# mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /usr/local/apache-maven-3.6.3
Java version: 11.0.7, vendor: Oracle Corporation, runtime: /usr/local/java/jdk-11.0.7
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "5.3.0-51-generic", arch: "amd64", family: "unix"

settings.xml 文件，加个国内镜像

<mirror>
 <id>aliyunmaven</id>
 <mirrorOf>*</mirrorOf>
 <name>阿里云公共仓库</name>
 <url>https://maven.aliyun.com/repository/public</url>
</mirror>

顶级父工程 pom.xml 添加，跳过单元测试编译和执行

<maven.test.skip>true</maven.test.skip>
<skipTests>true</skipTests>

如果有 Maven Nexus，则另外添加设置，install 替换为 deploy

Jenkins

nohup java -jar /usr/local/jenkins/jenkins.war --ajp13Port=-1 --httpPort=8086 >/usr/local/jenkins/jenkins.out 2>&1 &

Jenkins JDK 环境 >=1.8 and <=11 目前最新版本不支持 Java 14
Jenkins 安装一般会卡住 2 次，则是去国外下载插件数据缓慢的原因，kill -9 进程 ID，ps -ef | grep jenkins 找到进程 ID。

第一次卡住修改：/root/.jenkins/hudson.model.UpdateCenter.xml 文件里面链接内容为国内镜像地址 https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

第二次卡住执行替换命令：

cd /root/.jenkins/updates
sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json

Git or SVN

root@jazz-pc:/opt# which git
/usr/bin/git
root@jazz-pc:/opt# which svn
/usr/bin/svn

Jenkins CI/CD

Global Tool Configuration 设置好，JDK，Maven，Git
新建 Item，Freestyle project，如下

Item book-common

源码管理，选择 Git，填写 Repository URL 和 Credentials 设置 Jenkins 凭据
构建 Execute shell

#!/bin/bash
cd ./school
mvn clean install -pl com.lab:book-common -am -Ptest
echo 'install ok!'

Item book-web

源码管理略
Execute shell

#!/bin/bash
cd ./school/book-web
mvn clean package -Ptest
echo 'package ok!'
echo 'build start!'
service_name="book-web"
service_prot=80
IID=$(docker images | grep "$service_name" | awk '{print $3}')
echo "IID $IID"
if [ -n "$IID" ]
then
    echo "exist $service_name image,IID=$IID"
    docker rmi -f $service_name
    echo "delete $service_name image"
    docker build -t $service_name .
    echo "build $service_name image"
else
    echo "no exist $service_name image,build docker"
    docker build -t $service_name .
    echo "build $service_name image"
fi
CID=$(docker ps -a | grep "$service_name" | awk '{print $1}')
echo "CID $CID"

Dockerfile

位置和 pom.xml 路径平级，book-server 内容如下，其他略

FROM adoptopenjdk/openjdk11:jdk-11.0.7_10-alpine
VOLUME ["/tmp","/data/logs"]
COPY ./target/book-server-0.0.1-SNAPSHOT.jar book-server.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/book-server.jar","&"]
