jenkins回滚发布下拉案例1（二）

Description，描述字段

请选择版本

依赖：Referenced parameters UMI_CLUSTER,UMI_SERVICES

依赖环境，服务

其他使用默认值

3.流水线脚本执行内容

pipeline { agent { node { label 'master01' } } options { disableConcurrentBuilds() } environment { USERNAME = 'root' DEV_IP = '192.168.10.17' } stages { stage('Rollback Service') { steps { script { if (env.UMI_CLUSTER == 'dev') { env.MASTER_IP = "${env.DEV_IP}" } else if (env.UMI_CLUSTER == 'review') { env.MASTER_IP = "${env.REVIEW_IP}" } else if (env.UMI_CLUSTER == 'sit') { env.MASTER_IP = "${env.SIT_IP}" } else if (env.UMI_CLUSTER == 'uat') { env.MASTER_IP = "${env.UAT_IP}" } else if (env.UMI_CLUSTER == 'prod') { env.MASTER_IP = "${env.PROD_IP}" } else { sh 'exit 1' } } sh ''' set -e echo ${UMI_CLUSTER} echo ${UMI_SERVICES} echo ${UMI_VERSION} ssh ${USERNAME}@${MASTER_IP} "helm rollback ${UMI_SERVICES} `helm history ${UMI_SERVICES} |grep ${UMI_VERSION}|awk '{print \\$1}'`" ''' } } }}

jenkins 机器配置了免密登录到对应集群环境中

4.构建服务测试验证

回滚正常
