Building a Student REST API with Flask and Docker
- The article discusses the process of containerizing a Flask-based Student REST API using Docker for portability and consistency.
- Docker eliminates 'it works on my machine' issues by packaging apps and dependencies in containers for consistent operation.
- Steps include writing a Dockerfile with multi-stage builds, adding a .dockerignore file, building the image, running the container, and testing the API.
- Lessons learned include using slim base images, creating non-root users for security, and utilizing makefile targets for efficiency.
- Common errors encountered include slow build times, missing dependencies like Gunicorn, container conflicts, and Git ignores.
- Fixes involved checking network speeds, updating requirements.txt, removing conflicting containers/images, and updating Gitignore files.
- Tips emphasized include rebuilding images after changes, monitoring logs for debugging, cleaning up old resources, and documenting procedures.
- Future plans include sharing the Docker image on Docker Hub, expanding API endpoints, and enhancing test coverage for reliability.
- The article aims to help readers navigate the Dockerization process and avoid common pitfalls, ultimately making projects more portable and robust.
