Jenkins Docker 管道退出代码 -1 [英] Jenkins Docker Pipeline Exit Code -1

问题描述

我们有一个 Jenkinsfile，它使用 docker 插件在给定容器中运行脚本.这适用于某些图像，但在其他图像上会立即失败，并出现 -1 退出代码.我们已将错误减少到一个简单的sleep.这是 Jenkins 文件:

We have a Jenkinsfile that uses the docker plugin to run a script inside a given container. This works fine for some images, but fails immediately with a -1 exit code on others. We've reduced the error down to a simple sleep. This is the Jenkinsfile:

node("docker") {
    def wheezy_image = docker.image("pyca/cryptography-runner-wheezy")
    wheezy_image.pull()
    wheezy_image.inside {
        sh """sleep 120"""
    }
}

这是詹金斯的输出

有趣的是，如果睡眠时间少于 1 秒，那么它就会过去(但 120 秒的睡眠时间在许多其他图像上都可以正常工作).

Interestingly, if the sleep is less than 1 second then this passes (but the 120 second sleep works just fine on many of the other images).

作为参考，这是一个有效的 jessie 图像，和一个没有的 wheezy 图像.

For reference, here is a jessie image that works, and a wheezy image that does not.

有谁知道这里可能发生了什么?

Does anyone know what might be going on here?

推荐答案

看起来与您未安装 ps 的图像有关.我刚刚使用了 debian 基础，并且能够复制它不起作用.安装了ps，果然成功了.您也可以使用 withRun 函数，它可以工作.这是我的 Jenkins 文件:

Looks to be related to your image not having ps installed. I just took the debian base and was able to replicate that it wouldn't work. Installed ps, and it did work. You can also use the withRun function and it works. Here's my Jenkinsfile:

node("docker") {

    // Weezy that also ran... apt-get update && apt-get install -y procps
    def wheezy_image = docker.image("smalone/weezy-ps-test")
    wheezy_image.pull()
    wheezy_image.inside {
       sh 'sleep 2'
    }

      // Base image for weezy-ps-test that has no ps installed using withRun() instead of inside()
    wheezy_image = docker.image("debian:wheezy")
    wheezy_image.pull()
    wheezy_image.withRun { c ->
       sh 'sleep 2'
    }

    // Base image for weezy-ps-test that has no ps installed
    wheezy_image = docker.image("debian:wheezy")
    wheezy_image.pull()
    wheezy_image.inside {
       sh 'sleep 2'
    }
}

如果 docker 管道插件不存在，我会开一张票.

I'll open a ticket on the docker pipeline plugin, if one doesn't exist.

有一张票打开，但他们还没有找到根本原因.请参阅:https://issues.jenkins-ci.org/browse/JENKINS-40101 跟踪此问题的状态！

There was a ticket open, but they hadn't found the root cause yet. See: https://issues.jenkins-ci.org/browse/JENKINS-40101 to track the status of this issue!
