一.環境準備
k8s jenkins gitee harbor maven已經安裝
資源鏈接:https://gitee.com/jikeli/k8s-demo-docker.git
二.建立流水線node

node {
    env.BUILD_DIR="/root/build-workspace/"
    env.MODULE = "web-demo"
    env.HOST = "k8s.mooc.com"
    stage('Preparation'){
        git 'http://172.16.100.234:8033/root/k8s-demo-docker.git'
    }
    stage('Maven Build'){
        sh "/usr/local/maven/apache-maven-3.6.3/bin/mvn -pl ${MODULE} -am clean package"

    }
    stage('Build Image'){
        sh "/root/script/build-image-web.sh"
    }
    stage('Deploy'){
        sh "/root/script/deploy.sh"
    }
}
