如何锁定声明Jenkins管道的多个阶段？

Question

我想在声明的Jenkins管道中的锁内运行多个阶段:

pipeline {
    agent any
    stages {
        lock(resource: 'myResource') {
            stage('Stage 1') {
                steps {
                  echo "my first step"
                }
            }

            stage('Stage 2') {
                steps {
                  echo "my second step"
                }
            }

        }
    }
}

我收到以下错误:

Started by user anonymous
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 10: Expected a stage @ line 10, column 9.
           lock(resource: 'myResource') {
           ^

           lock(resource: 'myResource') {
           ^

           lock(resource: 'myResource') {
           ^

这有什么问题？该文件明确规定:

lock 也可用于将多个阶段包装到单个并发单元中

Answer 1

应该注意,您可以使用lock选项锁定管道中的所有阶段:

pipeline {
    agent any
    options {
        lock resource: 'shared_resource_lock'
    }
    stages {
        stage('will_already_be_locked') {
            steps {
                echo "I am locked before I enter the stage!"
            }
        }
        stage('will_also_be_locked') {
            steps {
                echo "I am still locked!"
            }
        }
    }
}

Answer 2

现在解决了这个问题,你可以通过在父级中对它们进行分组来锁定多个阶段,如下所示:

stage('Parent') {
  options {
    lock('something')
  }
  stages {
    stage('one') {
      ...
    }
    stage('two') {
      ...
    }
  }
}

(别忘了你需要Lockable Resources插件)

问题在于,尽管声明性管道在技术上已于2016年9月在测试版中提供,但您引用的博客文章(从10月开始)是记录脚本化管道,而不是声明性的(它没有说明,所以我觉得你的痛).可锁定资源尚未作为声明性管道步骤进行烘焙,以便启用您正在寻找的功能.

你可以做:

pipeline {
  agent { label 'docker' }
  stages {
    stage('one') {
      steps {
        lock('something') {
          echo 'stage one'
        }
      }
    }
  }
}

但你做不到:

pipeline {
  agent { label 'docker' }
  stages {
    lock('something') {
      stage('one') {
        steps {
          echo 'stage one'
        }
      }
      stage('two') {
        steps {
          echo 'stage two'
        }
      }
    }
  }
}

你做不到:

pipeline {
  agent { label 'docker' }
  stages {
    stage('one') {
      lock('something') {
        steps {
          echo 'stage one'
        }
      }
    }
  }
}

您可以为此用例使用脚本化管道.
