问题
I am setting up a CI workflow with Jenkins declarative pipeline and Docker-for-Windows agents through Dockerfile
.
Note: It is unfortunately currently not a solution to use a Linux-based docker daemon, since I need to run Windows binaries.
Setup: Jenkins master runs on Linux 16.04 through Docker. Jenkins build agent is
- Windows 10 Enterprise 1709 (16299.551)
- Docker-for-Windows 17.12.0-ce
Docker 18.x gave me headaches when trying to use Windows Containers, so I rolled back to 17.x. I still had some issues when trying to run with Jenkins and nohup not being on path, but it was solved by adding Git binaries to Windows search path (another reference). I suspect my current issue may be related.
Code: I am trying to initialize a Jenkinsfile
and run a simple hello-world-printout within.
/Jenkinsfile
pipeline {
agent none
stages {
stage('Docker Test') {
agent {
dockerfile {
filename 'Dockerfile'
label 'windocker'
}
}
steps {
println 'Hello, World!'
}
}
}
}
/Dockerfile
FROM python:3.7-windowsservercore
RUN python -m pip install --upgrade pip
Basically, this should be a clean image that simply prints "Hello, World!". But it fails on Jenkins!
Output from the log:

Cannot run program "id": CreateProcess error=2, The system cannot find the file specified
回答1:
The issue is, that windows is not supported at the moment. It is calling the linux "id" command to get the current user id.
There is an open Pull Request and JIRA Ticket at Jenkins to support Windows docker pipeline:
