DevOps实战(9) Jenkins项目配置生产环境

生产环境需要指定镜像版本号进行发布，所以需要配置 project  parameterized

 前后端pipeline脚本基本相同，设置不同集群对应镜像即可

#!groovy
pipeline {
    // environment {
        //IMAGE_TAG = sh (returnStdout: true, script: 'echo "build-${BRANCH_NAME//\\//_}-$BUILD_NUMBER"').trim()
    // }
    agent {
        node{
            label 'jenkins-slave'
        }
    }
    stages{
        stage('设置镜像版本'){
            steps{
                echo "镜像版本 = 10.12.20.20/railway/railway-site:$IMAGE_TAG"
            }
        }
        stage('发布'){
             steps{
                container('kubectl') {
                    script {
                        echo "部署项目"
                        withKubeConfig(clusterName: 'demo', contextName: 'railway', credentialsId: 'railwaycide', namespace: 'railway', serverUrl: 'https://10.12.20.67:9443/k8s/clusters/c-p2qj7') {
                            sh 'kubectl set image deployment/railway-site railway-site=10.12.20.20/railway/railway-site:$IMAGE_TAG --namespace railway'
                        }
                    }
                }
            }
        }
    }
    
}
