1. jenkins新建任务(流水线)

例如任务：avatar

2. jenkins -> 凭据 -> 添加凭据(username & password)

例如阿里云项目的个人配置username/password

3. avatar -> pipeline syntax

选择示例步骤 checkout：General SCM

• 填写Repository URL，git代码库地址链接
• 填写Credentials，选择凭据（用户）
• 点击生成流水线脚本

4. avatar -> 配置 -> 流水线

将步骤三生成的脚本填写到stage('checkout'){}，并补齐其他项

  脚本：
  node('jenkinsslave') {
    stage('checkout'){
        checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'c5b3bd5c-13ca-4a29-8dbb-870f5e663388', url: 'https://code.aliyun.com/icoastline-ilcfc/lcfc_issue_backend.git']]])
    }
    stage('Run shell') {
        sh 'sudo chmod 777 /etc/hosts'
        echo '\'192.168.2.226 registry.dev.com\' >> /etc/hosts'
    }
    stage('build'){
        sh 'sudo docker build ./api_issue/lcfc/test -t registry.dev.com:5000/icoastline/lcfc_issue_backend:${BUILD_NUMBER}'
        sh 'sudo docker push registry.dev.com:5000/icoastline/lcfc_issue_backend:${BUILD_NUMBER}'
    }
    stage('deploy'){
        sh 'sudo sed -i.bak \'s#IMAGE_VERSION#\'${BUILD_NUMBER}\'#\' ./api_issue/lcfc/test/test_deploy.yaml'
        sh 'sudo /home/data/common/kubectl apply -f ./api_issue/lcfc/test/test_deploy.yaml --kubeconfig /home/data/common/admin.conf'
    }
}

• 'Run shell'：镜像存储服务器地址。
• 'build'：通过Dockerfile生成镜像，并将image放到镜像存储服务器上。
• 'deploy'：替换pod部署文件test_deploy.yaml中image的IMAGE_VERSION为{BUILD_NUMBER}，并通过k8s的kubectl服务，通过部署文件test_deploy.yaml部署pod

5. avatar -> 立即构建

• Dockerfile：

FROM java:8-alpine
RUN mkdir -p /tmp/tar
COPY lcfc_iqc_backend-1.0-SNAPSHOT.jar /tmp/tar/lcfc_iqc_backend-1.0-SNAPSHOT.jar

RUN cd /tmp/tar
EXPOSE 8509
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","lcfc_iqc_backend-1.0-SNAPSHOT.jar"]
