DevOps（四）

1. CD

参考前面的流程图，我们正式开始CD的流程

Step 1 - 上传代码

• 安装git
  参考 Windows安装Git图文教程
• 配置IDEA
  参考 IDEA配置Git，以GitHub远程仓库为例
• 提交代码到本地 Commit
• gitlab账号密码：root/Newm123@
  
• gitlab创建项目，复制URL
  
• IDEA push代码
  会提示输入gitlab URL 账号密码
• 提交完成
  

Step 2 - 下载代码

• 在jenkins上创建pipeline项目
  
• 创建节点，并连接节点
  
  
• 配置jenkins gitlab（不配置也可以，因为我们在pipeline中也需要配置）
  Dashboard > Manage Jenkins >System
  
• 配置触发器（不配置也可以，在pipeline中也可以配置）
  
• pipeline片段

pipeline {
   
    agent {
    
        node {
    label 'node-133'}
            }

    stages {
   
        stage('Build') {
   
            steps {
   
                // Get some code from a GitHub repository
                git credentialsId: 'd3cb7c68-63e5-46d6-a505-d73a89902758', url: 'http://192.168.17.132:8929/devs/myjava.git'

                // Run Maven on a Unix agent.
                sh "mvn -Dmaven.test.failure.ignore=true clean package"

                // To run Maven on a Windows agent, use
                // bat "mvn -Dmaven.test.failure.ignore=true clean package"
            }

        }
    }
}

此处把mvn打包也一同配置了，并进行简单测试

[root@node-133 MyJava-Pipeline]# ll target/
total 4
drwxr-xr-x 2 root root   29 Jul 19 05:25 classes
drwxr-xr-x 3 root root   25 Jul 19 05:25 generated-sources
drwxr-xr-x 2 root root   28 Jul 19 05:25 maven-archiver
drwxr-xr-x 3 root root   35 Jul 19 05:25 maven-status
drwxr-xr-x 4 root root   54 Jul 19 05:25 MyJava-latest
-rw-r--r-- 1 root root 3054 Jul 19 05:25 MyJava-latest.war
[root@node-133 MyJava-Pipeline]# pwd
/opt/jenkins/workspace/MyJava-Pipeline

Step 3 - 检查代码

• 启动sonarqube，登录并设置密码
  http://192.168.17.133:9090
  admin/password
  
• 部署sonar-scanner

unzip sonar-scanner-cli-4.7.0.2747-linux.zip
cd sonar-scanner-4.7.0.2747-linux/
vim conf/sonar-scanner.properties
[root@dbc-server-554 sonar-scanner-4.7.0.2747-linux]# cat conf/sonar-scanner.properties
#Configure here general information about the environment, such as SonarQube server connection details for example
#No information about specific project should appear here

#----- Default SonarQube server
sonar.host.url=http://localhost:9090

#----- Default source code encoding
sonar.sourceEncoding=UTF-8
ln -sv /root/docker/sonar/sonar-scanner-4.7.0.2747-linux /usr/local/sonar-scanner
export PATH=/usr/local/sonar-scanner/bin:$PATH
source .bashrc
[root@dbc-server-554 sonar-scanner-4.7.0.2747-linux]# sonar-scanner -h
INFO:
INFO: usage: sonar-scanner [options]
INFO:
...

• 生成扫描命令
  

mvn clean verify sonar:sonar \
  -Dsonar.projectKey=MyJava \
  -Dsonar.host.url=http://192.168.17.133:9090 \
  -Dsonar.login=6b1dddd3274606082753ff907ee1b0380c28298a

部署jenkins pipeline

• pipeline片段

//定义http方法
def HttpReq(reqType,reqUrl,reqBody){
   
    sonarServer = "http://192.168.17.133:9090/api"
    // 可以不加authentication认证，因为默认不需要
    result = httpRequest  consoleLogResponseBody: true, 
                 httpMode: 'GET',
                 responseHandle: 'NONE', 
                 url: "${sonarServer}/${reqUrl}"                   
 //                customHeaders:[[name:'Authorization', value:"Basic ${credentials}"]]
    
    return result
}


//获取Sonar质量阈状态
def GetProjectStatus(projectName){
   
    apiUrl = "project_branches/list?project=${projectName}"
    response = HttpReq("GET",apiUrl,'')
    
    response = readJSON text: """${response.content}"""
    result = response["branches"][0]["status"]["qualityGateStatus"]
    
    println(response)
    
   return result
}
