Jenkins Pipeline + Gogs 实现 Spring Boot 项目 CI/CD

[TOC]

前言

CI/CD是什么呢？在软件开发过程中存在这繁琐的重复的“构建”、“发布”、“测试”工作，把这些工作进行流程化自动化的实践过程则可称之为CI/CD。而这个过程种可能需要到Kuberneters、Docker in Docker 、Pipeline等丰富的工具链和知识储备，而团队中又没有Kuberneters实现自动部署？我们团队成员也没有太多时间学习掌握Pipeline呢？完成自动构建后又如何实现jar的自动上传和优雅地重启呢？面对这些问题该如何解决呢？而这里将通过 SSH 将应用部署到远程主机以满足非容器化的场景需求。通过Jenkinsfile以及scm模式实现项目零配置。最后通过sh脚本实现程序地发布和优雅地重启。

Jenkins 部署

环境准备

安装 Docker
配置 yum 源
## 配置默认源
## 备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

## 下载阿里源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

## 刷新
yum makecache fast



## 重建yum缓存
yum clean all
yum makecache fast
yum -y update
安装 Docker

下载docker的yum源文件

yum -y install yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

这里指定 Docker 版本，可以先查看支持的版本

[root@localhost ~]# yum list docker-ce --showduplicates |sort -r               
 * updates: mirrors.aliyun.com
Loading mirror speeds from cached hostfile
Loaded plugins: fastestmirror

...
 * base: mirrors.aliyun.com

目前最新版本为19.03，指定下载18.09

yum install -y docker-ce-18.09.9-3.el7
systemctl enable docker
systemctl start docker
新建 Jenkins 专用用户组和用户
groupadd -g 1000 jenkins
useradd -u 1000 -g 1000 -s /sbin/nologin jenkins
安装 Maven 工具
## 下载 Maven
wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

## 解压至指定目录供后续调用
tar xzf apache-maven-3.6.3-bin.tar.gz /opt

安装 Jenkins

通过 Docker 安装 Jenkins
docker run -d --name jenkinsci --restart=always -p 1080:8080 -v /home/jenkins:/var/jenkins_home -v /opt/apache-maven-3.6.3:/opt/maven dockerhub.azk8s.cn/jenkins/jenkins:2.204.2
解锁 Jenkins

当您第一次访问新的Jenkins实例时，系统会要求您使用自动生成的密码对其进行解锁。

  1. 浏览到 http://localhost:1080（或安装时为Jenkins配置的任何端口），并等待 解锁 Jenkins 页面出现。
    avatar

  2. 从Jenkins控制台日志输出中，复制自动生成的字母数字密码（在两组星号之间


    avatar
安装插件

通过Jenkins中的Manage Jenkins > Manage Plugins 安装本案用到得插件 。

  • Timestamper
  • Pipeline
  • Pipeline: Stage View
  • Generic Webhook Trigger
  • Git
  • Email Extension
  • Mailer
  • SSH Pipeline Steps
  • Gogs

部署项目

环境准备

部署 Java 运行环境
## 安装 OpenJDK
yum install -y java-1.8.0-openjdk

## 配置 JAVA_HOME 环境变量

cat <<EOF >  /etc/profile
JAVA_HOME=/usr/lib/jvm/java
CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
PATH=${PATH}:${JAVA_HOME}/bin:/usr/local/bin
export JAVA_HOME CLASSPATH PATH
EOF
source /etc/profile
配置 SSH 证书访问

生成 SSH 证书

ssh-keygen -t rsa -b 4096

修改服务器 ssh 配置文件

vi /etc/ssh/sshd_config


## 是否允许用户自行使用成对的密钥系统进行登入行为，仅针对 version 2。
## 至于自制的公钥数据就放置于用户家目录下的 .ssh/id_rsa.pub
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile %h/.ssh/id_rsa.pub

重启 SSH

systemctl restart sshd

验证 SSH 证书登录过

ssh -h localhost -i ~/.ssh/id_rsa -l root
为 Jenkins 配置 SSH 部署私钥

  1. 在凭据-->系统中找到“全局凭据”


    avatar

  2. 添加一个全局凭据，类型选择为“SSH Username with private key”


    avatar

  3. 将私钥粘贴到“private Key”中，并将ID设置为 root10.168.1.42 供后续使用，然后保存


    avatar

    avatar
Gogs 仓库准备

  1. 新建 Spring Boot 项目


    avatar

  2. 在项目中增加 Jenkinsfile 与 Launch 文件，并推送到Gogs仓库


    avatar

  3. 根据项目实际情况修改 Jenkinsfile 配置

    avatar

    Note:

  • token 必须根据不同项目设置为不同的值，供 Jenkins 识别不同项目
  • 如需对应用设置不同端口或profile，可通过 java_opts 配置
    • 将端口设置为 1999 则 java_opts = "-Dserver.port=1999"
    • 使用 dev profile 则 java_opts = "-Dspring.profiles.active=dev"

部署项目

  1. 新建一个任务


    avatar

  2. 输入自己任务的名称，然后选择流水线，流水线才是pipeline。


    avatar

  3. 确认之后管理界面，如果做过了解的应该知道，piepeline有两种方式，一种是直接写script另一种是引入SCM。这里使用第二种方式


    avatar

  4. 保存配置后进入项目界面，点击立即构建，稍等片刻待项目构建完成，并查看项目构建日志。

设置 Gogs 钩子

  1. 添加Web钩子
    登录代码管理系统，进入仓库设置→管理Web钩子→添加Web钩子。


    avatar
  2. 设置web钩子的详情
    这里的推送地址是http://jenkins地址:端口号/generic-webhook-trigger/invoke?token=密钥，这里的密钥是要与前面在Jenkinsfile里面的密钥设置一致。触发web钩子的事件可以自己设置什么样的事件去触发jenkins的构建。
    avatar

这里设置完了之后可以点击测试推送，点击测试记录可以看到发送给jenkins的推送详情了。其中ref就是推送过去的分支啦。以下的推送的内容都是可以通过设置jenkins变量来获得的。（底下红色圈出的部分是Jenkinsfile中配置的变量）


avatar

  1. 验证钩子触发 Jenkins 自动构建
    在项目目录提交代码变更，并将提交信息填写为"ci test"便于查看，并推送。


    avatar

    片刻后 Jenkins 便构建完成，查看提交信息及日志发现项目由 Gogs 钩子触发构建完成。
