如何以编程方式确定哪些Jenkins从节点已用于运行构建？ [英] How to programmatically determine which Jenkins slave node has been used to run a build?

问题描述

让我们说，我已经配置了一个Jenkins作业，它可以在几个Jenkins从节点（例如Node1，Node2，Node3等）上运行。当一个构建启动时，Jenkins将选择一个可用的Jenkins slave来运行Build。

Let's says I have configured a Jenkins job which can run on a few Jenkins slave nodes (e.g. Node1, Node2, Node3, etc). When a build is started, Jenkins will select an available Jenkins slave to run the Build.

对于已经完成或正在运行的构建， Jenkins从节点已被用于运行Build？

For a Build which has completed, or is currently running, how to programmatically determine which Jenkins slave node has been used to run the Build?

推荐答案

您可以使用 Jenkins REST API 查询现有版本，假设您知道版本号：

You can use the Jenkins REST API to query an existing build assuming you know the build number:

http：// jenkins：8080 / job / JOB_NAME / 100 / api / json？pretty = true

builtOn 字段显示正在运行/运行构建的从属的名称。

The builtOn field shows the name of the slave which is running/ran the build.

要仅检索JSON构建信息的几个字段，请使用树参数：

To retrieve only a couple fields of the JSON build information, use the tree parameter:

http：// jenkins：8080 / job / JOB_NAME / 100 / api / json？tree = id，timestamp，builtOn& pretty = true

这将返回类似的结果：

{
  "id" : "2014-12-01_06-18-17",
  "timestamp" : 1417443497917,
  "builtOn" : "sdev05"
}

Jenkins UI中的大多数页面底部都有一个REST API 链接，以编程方式查询。

Most pages in the Jenkins UI have a REST API link at the bottom indicating they expose information that can be queried programmatically.
