持续交付（六）-- jenkins构建生产环境与测试环境分离的流水线任务

既然生产环境与测试环境要分离，就需要各自维护自己的一套环境

通过jenkins里的项目参数可以选择构建在那个环境

生产环境与测试环境

• 使用不同的数据库配置文件
• docker实例端口也要配置不相同的端口
• docker 启动不同的镜像，使用不同的容器的名字

所以需要通过变量来区分生产环境与测试环境,jenkinsfile如下

pipeline {
    agent {
        label 'master'
    }

    environment {
        docker_image = 'jeesite4'
        docker_container = 'iJeesite4'
    }

    parameters {
        string(name: 'branch', defaultValue: 'master', description: 'Git branch')
        choice(name: 'env', choices: ['prod', 'qa'], description: 'Environment Type')
    }

    stages{
        stage('同步源码') {
            steps {
                git url:'https://gitee.com/testingl/JeeSite4.git', branch:'${branch}'
            }
        }

        stage('设定配置文件'){
            steps{
                sh '''

                        export mysql_port=${mysql_prod_port}
                    else

                '''
            }
        }

注意：这里我们需要启动连个不同名字的mysql容器，名字和application-${env}.yml一致

jenkins构建流水线任务，配置pipeline SCM拉取代码，指定流水线执行脚本

构建一次之后，jenkins界面中会自动生成参数配置
