如何使后续结帐 scm 阶段在 Jenkins 管道中使用本地存储库？

Question

我们使用 Jenkins ECS 插件为我们构建的“每个”作业生成 Docker 容器。所以我们的管道看起来像

node ('linux') {
  stage('comp-0') {
    checkout scm
  }
  parallel(
    "comp-1": {
      node('linux') {
        checkout scm
      ...
      }
    }
    "comp-2": {
      node('linux') {
        checkout scm
      ...
      }
    }
  )
}

上述管道将生成 3 个容器，每个节点（'linux'）调用一个。

我们在 Jenkins 配置页面中设置了一个“linux”节点来告诉 Jenkins 我们想要生成的 Docker 存储库/映像。它的设置有一个“容器挂载点”的概念，我假设它是容器可以访问的主机上的挂载。

所以在上面的管道中，我希望“第一个”结帐 scm 将我们的 repo 克隆到由我们的容器安装的主机路径上，例如 /tmp/git。然后，我希望后续的 'checkout scm' 行将 repo 克隆到主机的 /tmp/git 路径中。

我正在查看 How to mount Jenkins workspace in docker container using Jenkins pipeline 以了解如何将本地路径安装到我的 docker 上

这可能吗？

您可以存储结帐 scm 步骤中的代码，然后在后续步骤中将其取消存储。这是 Jenkins 流水线文档中的一个示例。

// First we'll generate a text file in a subdirectory on one node and stash it.
stage "first step on first node"

// Run on a node with the "first-node" label.
node('first-node') {
    // Make the output directory.
    sh "mkdir -p output"

    // Write a text file there.
    writeFile file: "output/somefile", text: "Hey look, some text."

    // Stash that directory and file.
    // Note that the includes could be "output/", "output/*" as below, or even
    // "output/**/*" - it all works out basically the same.
    stash name: "first-stash", includes: "output/*"
}

// Next, we'll make a new directory on a second node, and unstash the original
// into that new directory, rather than into the root of the build.
stage "second step on second node"

// Run on a node with the "second-node" label.
node('second-node') {
    // Run the unstash from within that directory!
    dir("first-stash") {
        unstash "first-stash"
    }

    // Look, no output directory under the root!
    // pwd() outputs the current directory Pipeline is running in.
    sh "ls -la ${pwd()}"

    // And look, output directory is there under first-stash!
    sh "ls -la ${pwd()}/first-stash"
}
