Jenkins pipeline 08 when 阶段运行控制

when 阶段运行控制

判断条件
• 根据环境变量判断
• 根据表达式判断
• 根据条件判断（not/allOf/anyOf）  

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'build......'
            }
        }
        stage('Deploy') {
            when {
                environment name: 'DEPLOY_TO', value: 'DEV'
            }
            steps {
                echo 'Deploying.......'
            }
        }
    }
}
###  allOf 条件全部成立
 when {
     allOf {
         environment name: 'CAN_DEPLOY', value: 'true'
         environment name: 'DEPLOY_ENV', value: 'dev'
     }
 }
### anyOf 条件其中一个成立
when {
     anyOf {
         environment name: 'CAN_DEPLOY', value: 'true'
         environment name: 'DEPLOY_ENV', value: 'dev'
     }
 }

when是去控制的，什么时候去执行，什么时候去不执行，比如通过input去拿到选项参数.

when就是根据变量或者表达式等等其他条件去判断阶段能不能运行.

这里使用环境变量去测试

    environment{
      ENV_TYPE = "DEV"
      description = "版本号"
    }



        stage('deploy') {
             when {
                    environment name: 'ENV_TYPE', value: 'DEV'
                    }
             
             steps {
                script{
                      echo "deploy dev"  
                }
            }
   
        }

 这样就会先去判断变量是否成立，成立了之后才会去运行 

成功
[Pipeline] echo (hide)
deploy dev
[Pipeline] }
[Pipeline] // script


失败
[Pipeline] { (deploy)
Stage "deploy" skipped due to when conditional
