Jenkins pipeline: Run python script

Question

I want to run a python file or set of python commands via a JenkinsFile. How do I approach this?

I run the code below and My Jenkins Job never finishes.

pipeline {
    agent { docker { image 'python:3.5.1' } }
    stages {
        stage('build') {
            steps {
                sh 'python --version'
            }
        }
    }
}

As you are using one of the hello world examples of Jenkins (jenkins.io/doc/pipeline/tour/hello-world) your code should work. Is your Jenkinsfile placed in your repository? Or can you provide more jenkins output? — Michael Kemmerzell

Yes, I am using same jenkins example as mentioned in Windows machine.. Caused: java.io.IOException: Cannot run program "nohup" (in directory "D:\OCIPlatformIDC\jenkins\workspace\githubpipeline"): CreateProcess error=2, The system cannot find the file specified — Pritish

Where is your docker host, on same Windows machine as of Jenkins? and have you configured it in the Jenkins global configuration. — SunilThorat

I got your pipeline working by following the below steps:

Create a Pipeline job with the code you posted in the question.

pipeline {
    agent { docker { image 'python:3.5.1' } }
    stages {
        stage('build') {
            steps {
                sh 'python --version'
            }
        }
    }
}

Install docker on the virtual machine console and add the jenkins user to docker group

sudo apt install docker.io
sudo systemctl enable docker
sudo systemctl start docker
docker --version
> Docker version 18.09.2, build 6247962
sudo usermod -a -G docker jenkins

Run the job, you must get a success and python version like in below screenshot.

Feel free to ask any questions, if required.

Jenkins installed in Windows, Docker as well. So do I have to add the Jenkin user to docker group? I am getting below mentioned error for jenkins build: Caused: java.io.IOException: Cannot run program "nohup" (in directory "D:\OCIPlatformIDC\jenkins\workspace\githubpipeline"): CreateProcess error=2, The system cannot find the file specified
