Thanks for your contribution. We build this project in the GitHub actions. So, would you mind adding the build script of your PR into the GitHub actions?

By the way, I'm not familiar with Python programming. It would be great if you can provide a sample Python project. Then I can test this PR with it.

I have already added the build script, waiting for Github actions to build image. Currently, I will build the image locally, and then use the project on github for testing

@LinuxSuRen I have tested this image locally, sample project is thefuck, sample workflow ref here and the jenkinsfile I have been used are as follow:

pipeline {
    agent {
        label 'python37'
    }

    stages {
        stage('Checkout') {
            steps {
                git branch: 'master', credentialsId: 'github', url: 'git@github.com:nvbn/thefuck.git'
            }
        }
        stage('Install dependencies') {
            steps {
                container('python') {
                    sh '''
                      pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -Ur requirements.txt coveralls
                      python setup.py develop
                    '''
                }
            }
        }
        stage('Run tests') {
            steps {
                container('python') {
                    sh 'coverage run --source=thefuck,tests -m pytest -v --capture=sys tests'
                }
            }
        }
    }
}

Hi @yuezhuangshi , thanks for your contriubution.

I think we are missing docker image declaration in README.md. Can you help us add it in another PR?
