If I define environment variables in my Jenkinsfile https://www.jenkins.io/doc/pipeline/tour/environment/, where are they stored in the agent? I am specifically using Kubernetes plugin, and when I go into any of my containers and do printenv I don't see any of the environment variables I specified there. Where are they stored specifically? I am asking because I have a legacy Jenkinsfile that defined a lot of environment variables but it seems a lot of them are not used anymore, and I want to clean them up.

如果我在我的Jenkins文件https://www.jenkins.io/doc/pipeline/tour/environment/,中定义环境变量,它们在代理中存储在哪里?我专门使用Kubernetes插件,当我进入我的任何容器并执行print tenv时,我没有看到我在那里指定的任何环境变量。它们具体存储在哪里?我问这个问题是因为我有一个遗留的Jenkins文件,它定义了许多环境变量,但似乎有很多变量已经不再使用了,我想要清理它们。

In Jenkins, when you define environment variables in a Jenkinsfile using the environment block, those variables are scoped to the Jenkins Pipeline job itself, and they are not directly stored in the agent's environment where you would see them with printenv or similar commands. These variables are specific to the Jenkins Pipeline runtime.

在Jenkins中,当您使用环境块在Jenkins文件中定义环境变量时,这些变量的作用域为Jenkins管道作业本身,并且它们不会直接存储在代理的环境中,您可以在代理环境中使用print tenv或类似命令看到它们。这些变量特定于Jenkins管道运行时。


These environment variables are typically injected into the environment of the agent's processes spawned by the Jenkins Pipeline job during its execution. They are used to provide configuration or data to the job, but they won't be visible in a shell outside of the Jenkins Pipeline context.

这些环境变量通常被注入到Jenkins管道作业在其执行期间产生的代理进程的环境中。它们用于向作业提供配置或数据,但它们不会在Jenkins管道上下文之外的外壳中可见。

So they are only useful to be used in the Jenkinsfile itself right? They can't be used implicitly by any program ran inside the file (e.g. a Python code run inside a stage cannot expect an environment variable defined here to be accessible)?

所以它们只在JenkinsFILE中使用,对吗?它们不能被在文件中运行的任何程序隐式使用(例如,在舞台中运行的Python代码不能期望这里定义的环境变量是可访问的)?

This is exactly how I understand it and this is how it works in my examples. Please take a look at this plugin: plugins.jenkins.io/envinject maybe it will help. (I haven't tested it)

这正是我对它的理解,这就是我的例子中的工作原理。请看一下这个插件:plugins.jenkins.io/envinject,也许它会有帮助。(我还没有测试过)
