Jenkins Docker Pipeline Exit Code -1

问题

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"""
    }
}

And here's the jenkins output

+ docker pull pyca/cryptography-runner-wheezy

ERROR: script returned exit code -1

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).

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

Does anyone know what might be going on here?

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'
    }
}

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

EDIT: 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!
