从詹金斯(Jenkins)在后台启动shell脚本的干净方法 [英] Clean way of launching a shell script in background from Jenkins

问题描述

从jenkins启动脚本，不使构建挂起并使进程运行的正确方法是什么?我似乎无法正常工作.脚本无法运行或构建挂起.

What's the proper way to launch a script from jenkins, don't get the build hanging, and leave the process running? I can't seem to get it to work. Either the script doesn't run or the build hangs.

如果我将构建的执行外壳"步骤放入bash relaunch.sh &或relaunch.sh > output.log &或nohup bash relaunch.sh &， 什么都没发生;构建完成，但该过程未运行.我想这可能与詹金斯(Jenkins)等待错误管道关闭有关.

If I put in the build's "Execute shell" step bash relaunch.sh & or relaunch.sh > output.log & or nohup bash relaunch.sh &, nothing happens; build finishes, but the process doesn't run. I guess it can be related to Jenkins waiting for the error pipe to close.

如果我愿意 nohup bash relaunch.sh 2>&1 > output.log根据建议此处，输出已正确重定向，但构建挂起(未完成)，并且在我终止构建时进程死了.

If I do nohup bash relaunch.sh 2>&1 > output.log as suggested here, the output is properly redirected, but the build hangs (doesn't finish), and the process dies when I kill the build.

根据建议添加export BUILD_ID=dontKillMe，此处，此处和

Adding export BUILD_ID=dontKillMe, as suggested here, here, and here, either to the "Execute shell" step or the script itself doesn't help either. The build hangs and the process dies when I kill the build. Needless to say, my knowledge of linux is very limited.

人们如何以一种干净的方式做到这一点?

How do people do this in a clean way?

推荐答案

一种简便的实现方法是更改​​ Execute shell 下的环境变量BUILD_ID，其中Jenkins's ProcessTreeKiller .

A convenient way to achieve that is to change the environment variable BUILD_ID under Execute shell which Jenkins's ProcessTreeKiller is looking for.

这样做，

BUILD_ID=dontKillMe nohup bash relaunch.sh &

Jenkins将假定后台作业不是由构建生成的，并且不会在完成作业后杀死它们.

Jenkins will assume that the background job is not spawned by the build and will not kill them after finishing the job.

感谢 Joshua 的观察，他也可以将JENKINS_NODE_COOKIE用作

Thanks to Joshua for his observation that you could also use JENKINS_NODE_COOKIE as

JENKINS_NODE_COOKIE=dontKillMe
