I have a python + selenium script that I have run successfully standalone and run with a Docker container.
I simply wish to create a pipeline that automates its execution (cd to a child folder and execute the script), but this fails consistently with an error indicating the file cannot be found??? I have tried both expressing the fully qualified path in the windows form and as /mnt/… neither works.
Can someone help with a simple template or direct me to a topic that guides me through this setup?

Hello,
It sounds like you’re encountering a common issue with file paths in automated pipelines. Let’s go through a simple template and some best practices to help you set up your pipeline correctly.
Simple Pipeline Template
Here’s a basic example of a pipeline script using Python and Selenium, assuming you’re using a CI/CD tool like Jenkins, GitHub Actions, or Azure Pipelines:
Directory Structure
project/
├── scripts/
│ └── your_script.py
├── Dockerfile
├── Jenkinsfile (or .github/workflows/main.yml for GitHub Actions)
└── requirements.txt
Dockerfile
FROM python:3.8-slim
WORKDIR /app
COPY requirements.txt requirements.txt
RUN pip install -r requirements.txt
COPY scripts/ scripts/
CMD ["python", "scripts/your_script.py"]
Jenkinsfile (for Jenkins):
pipeline {
agent any
stages {
stage('Build') {
steps {
script {
docker.build('your-image-name')
}
}
}
stage('Run') {
steps {
script {
docker.image('your-image-name').inside {
sh 'python scripts/your_script.py'
}
}
}
}
}
}
GitHub Actions Workflow (.github/workflows/main.yml):
name: CI
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Set up Python
uses: actions/setup-python@v2
with:
python-version: 3.8
- name: Install dependencies
run: |
python -m pip install --upgrade pip
pip install -r requirements.txt
- name: Run script
run: |
python scripts/your_script.py
Troubleshooting Tips
Check File Paths:
Ensure the paths are correct and relative to the working directory of your pipeline.
Use absolute paths if necessary, but ensure they are correctly referenced.
Permissions:
Ensure the script has the necessary permissions to execute.
Check if the Docker container has the correct permissions to access the files.
Environment Variables:
Use environment variables to manage paths and other configurations dynamically.
Debugging:
Add logging to your script to print the current working directory and the paths being accessed.
Use os.getcwd() and os.listdir() to debug path issues.
Hope this will help you.
