Jenkins 流水线:“输入"步骤块执行器 [英] Jenkins Pipeline: "input" step blocks executor

问题描述

经过 管道 和 Jenkinsfile 文档，我对如何创建 Stage -> Production 管道有点困惑.

After going through the pipeline and Jenkinsfile documentation, I am a bit confused on how to create a Stage -> Production pipeline.

一种方法是使用 input 步骤，如

One way is to use the input step like

node() {
  stage 'Build to Stage'
  sh '# ...'

  input 'Deploy to Production'
  stage 'Build to Production'
  sh '# ...'
}

这似乎有点笨拙，因为这会一直阻塞执行程序，直到您想要部署到生产环境.有没有其他方法可以从 Jenkins 部署到生产环境.

This seems a bit clunky, as this will block an executor all the time until you want to deploy to production. Is there any alternative way of being able to deploy to production, from Jenkins.

推荐答案

EDIT (Oct 2016): Please see my other answer "Use milestone and lock" below, which includes recently introduced features.

作为第一个选项，您可以将 sh 步骤包装到 timeout 步骤.

As first option, you can wrap your sh step into a timeout step.

node() {
  stage 'Build to Stage' {
    sh '# ...'
  }

  stage 'Promotion' {
    timeout(time: 1, unit: 'HOURS') {
      input 'Deploy to Production?'
    }
  }

  stage 'Deploy to Production' {
    sh '# ...'
  }
}

这会在超时后停止构建.

This stops the build after the timeout.

另一种选择是不为 input 步骤分配重量级执行器.您可以使用 node 块之外的 input 步骤来执行此操作，如下所示:

Another option is to not allocate a heavyweight executor for the input step. You can do this by using the input step outside of the node block, like this:

stage 'Build to Stage' {
  node {
      sh "echo building"
      stash 'complete-workspace'
  }
}

stage 'Promotion' {
  input 'Deploy to Production?'
}

stage 'Deploy to Production' {
  node {
    unstash 'complete-workspace'
    sh "echo deploying"
  }
}

这个是 是 可能是更优雅的方式，但仍然可以与 timeout 步骤结合使用.

This is was probably the more elegant way, but can still be combined with the timeout step.

正如@a​​muniz 所指出的，您必须存储/取消存储工作区的内容，因为可能会为两个 node 步骤分配不同的节点和工作区目录.

As pointed out by @amuniz, you have to stash/unstash the contents of the workspace, as different nodes respectively workspace directories might be allocated for the two node steps.
