pipeline流水线构建

1.流水线创建

2.创建秘钥

2.1通过http账号密码方式

2.2通过ssh方式

3.根据脚本构建应用

def label = "jenkins-slave"
podTemplate(label: label, cloud: 'kubernetes',




)
{
node(label) {
        stage('pull code') {
            checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '6dabf361-4478-47c3-aba9-dc6e3d15795f', url: 'https://codeup.aliyun.com/61233c140fc7bf0dbe1e642d/docker-demo.git']]])
        }
        stage('build') {
            echo "开始进行代码编译并推送到镜像仓库"
             sh '''
              echo ${IMAGE_VERSION}-$BUILD_NUMBER-`git log -n1 --format=format:%h` > image_version.txt
              cat image_version.txt
              echo "测试 Kubernetes 动态生成 jenkins slave"

                docker login -u admin -p harbor 192.168.56.11:8084
                 mvn clean package -Dmaven.test.skip=true   
                 cp /home/jenkins/agent/workspace/pipelineDemo/target/demo.jar ./
                 
                 docker build -t 192.168.56.11:8084/demo/${IMAGE_NAME}:`cat image_version.txt`  .
                 docker push 192.168.56.11:8084/demo/${IMAGE_NAME}:`cat image_version.txt`
              '''  
            echo "镜像编译结束"
        }
        stage('packageChart') {
            echo "准备开始打chart包，并上传"
            sh '''
            
            helm repo add --ca-file /etc/docker/certs.d/ca.crt --username admin --password harbor myrepo https://192.168.56.11/chartrepo/demo
            cp image_version.txt k8s/helm/
            cd k8s/helm

            sed -i "s/{{IMAGE_NAME}}/${IMAGE_NAME}/g" values.yaml
            sed -i "s/{{IMAGE_VERSION}}/`cat image_version.txt`/g" values.yaml
            cat values.yaml
            sed -i "s/{{JENKINS_NUM}}/$BUILD_NUMBER/g" Chart.yaml
            sed -i "s/{{CHART_NAME}}/${CHART_NAME}/g" Chart.yaml
            sed -i "s/{{CHART_VERSION}}/${CHART_VERSION}/g" Chart.yaml
            
            cat Chart.yaml
            helm package .
            echo ${CHART_NAME}-${CHART_VERSION}.$BUILD_NUMBER.tgz > tgz.txt
            cat tgz.txt
            curl --request POST      --form chart=@`cat tgz.txt`      --user admin:harbor      https://192.168.56.11/api/chartrepo/demo/charts  --cacert /etc/docker/certs.d/ca.crt
            '''
            echo "打包结束"
        }

        stage('deploy') {
            echo "准备开始部署"
             sh '''
                helm repo add --ca-file /etc/docker/certs.d/ca.crt --username admin --password harbor myrepo https://192.168.56.11/chartrepo/demo
                helm repo update 
                cd k8s/helmValue
                helm upgrade myapp  myrepo/${CHART_NAME} -n default --version ${CHART_VERSION}.$BUILD_NUMBER -f dev.yaml
              '''

    }

3.1代码拉取介绍

checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '6dabf361-4478-47c3-aba9-dc6e3d15795f', url: 'https://codeup.aliyun.com/61233c140fc7bf0dbe1e642d/docker-demo.git']]])
# 1.credentialsId为jenkins配置的秘钥
# 2.url为请求url地址
# 3.若是url使用ssh方式 那么配置的credentialsId也应该为ssh，反之同理

3.2自定义参数使用

使用方法为 ${CHART_NAME}
