Jenkins指定tag发布到k8s环境

Jenkins指定tag发布到k8s环境

1、Jenkins配置一个Pipeline 工程

首先要安装插件：https://www.cnblogs.com/Dev0ps/p/9125232.html

参数化构建过程

Pipeline选择Pipeline script from SCM

保存之后构建失败会提示找不到Jenkinsfile,我们只需要新建相应的Jenkinsfile文件即可

vim /root/.jenkins/workspace/sscp-xxx_sit@script/Jenkinsfile

node (){ //指定Slave标签

   stage('Git Checkout') {

      checkout([$class: 'GitSCM', branches: [[name: '${Tag}']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[url: '[email protected]:xx/xx.git']]])   }   //代码编译

   stage('Maven Build') {

        sh '''

        export JAVA_HOME=/usr/local/java

        /usr/local/maven/bin/mvn clean package -Ppresit -Dmaven.test.skip=true

        '''

   }

   stage('Build and Push Image') {

sh '''

REPOSITORY=172.31.182.143/presit/sscp-xxx:${Tag}

cp Dockerfile target/

cd target

docker build -t $REPOSITORY .

docker login -u admin -p Harbor%12345 172.31.182.143

docker push $REPOSITORY

'''

}

    stage('Deploy to k8s') {

    sh '''

        K8S_MASTER="172.31.182.152"

        APP="sscp-xxx"

        ENV="presit"

        ssh ${K8S_MASTER} -t "cd /root/helm/source/sscp-config/sscp-${ENV}/sscp-deploy-config;git checkout ${ENV};git pull"

        ssh ${K8S_MASTER} cp /root/helm/source/sscp-config/sscp-${ENV}/sscp-deploy-config/${APP}/values.yaml /root/helm/sscp-${ENV}/${APP}/values.yaml

        ssh ${K8S_MASTER} helm upgrade ${APP}-${ENV} -f /root/helm/sscp-${ENV}/${APP}/values.yaml --set app.updateVersion=`date +%s` chartmuseum/${APP} --set app.image.tag=${Tag}

        '''

    }

}
