This document outlines the Continuous Integration and Continuous Deployment (CI/CD) pipeline for the TinyGallery Backend project.
Our CI/CD pipeline automates the process of testing, building, and deploying the TinyGallery Backend. It ensures that all changes are thoroughly tested before being deployed to production.
- The pipeline starts by checking out the latest code from the main branch of our Git repository.
- Set up a Python virtual environment.
- Install all required dependencies from
requirements.txt
.
- Run
flake8
to check for any code style issues. - Ensure all Python files conform to PEP 8 standards.
- Run all unit tests using
pytest
. - Generate a test coverage report.
- Set up a test database.
- Run integration tests that interact with the database and API endpoints.
- Perform a security scan using a tool like
bandit
to identify any potential security vulnerabilities.
- If all previous stages pass, create a Docker image of the application.
- Push the Docker image to our container registry (e.g., Docker Hub, AWS ECR).
- For the main branch:
- Deploy to the staging environment.
- Run smoke tests to ensure basic functionality.
- If smoke tests pass, deploy to production.
- For feature branches:
- Deploy to a temporary environment for review.
- Run a suite of end-to-end tests on the deployed application.
- Monitor application performance and error rates.
- Set up alerts for any unusual activity or errors in the production environment.
- Regularly review logs and performance metrics.
In case of a failed deployment or critical issues in production:
- Immediately revert to the last known good version.
- Investigate the cause of the failure.
- Fix the issue in a separate branch.
- Re-run the entire pipeline before attempting to deploy again.
- Deployment to production requires manual approval from a team lead or senior developer.
Our pipeline is configured using [CI/CD tool name, e.g., Jenkins, GitLab CI, GitHub Actions]. The configuration file can be found at [location of configuration file].
- Always write and update tests for new features and bug fixes.
- Regularly update dependencies and address any security vulnerabilities.
- Review and optimize the pipeline regularly for better performance and reliability.
This CI/CD pipeline ensures that our TinyGallery Backend is thoroughly tested and safely deployed. It helps maintain high code quality and reduces the risk of introducing bugs into production.
