Production-Ready Python Engineering & DevOps Bundle

Stop struggling with server deployment and multi-container setups. Get battle-tested, production-ready configurations in minutes.

The Production-Ready Docker & Linux Pocket Guide is a concise, hands-on reference designed for software developers, computer science students, and engineers who want to bridge the gap between local development and real-world cloud deployment.

Instead of wading through hundreds of pages of abstract theory, this guide cuts straight to the chase with actionable commands, practical Dockerfiles, and security best practices you can copy-paste directly into your projects.

• Linux CLI & VPS Essentials: Key commands for server management, file permissions, memory inspection, and port monitoring.
• Docker Core & Container Lifecycle: A cheat sheet for building, running, inspecting, and managing containers efficiently.
• Production Dockerfiles: Battle-tested setups for Python (FastAPI/Flask) and Node.js (Express) using lightweight base images
• Multi-Container Orchestration: Ready-to-use docker-compose.yml linking web services with production-ready PostgreSQL databases.
• Security & System Cleanup: Non-root execution practices, UFW firewall configurations, and system pruning workflows.

• Developers looking to containerize their apps quickly without trial and error.

Python Testing with pytest is a practical guide to building reliable Python software through automated testing.

Writing code that works is only the beginning. As projects grow, refactoring, new features, and changing requirements can introduce unexpected regressions. A well-designed test suite provides the safety net developers need to change their code with confidence.

This capsule introduces pytest from the ground up and gradually moves toward the practices used in real-world Python projects.

You will learn how to write clear and focused tests, use assertions effectively, test normal and edge-case behavior, verify exceptions, organize test code, understand pytest output, and build a repeatable testing workflow.

The book also introduces the principles behind Arrange–Act–Assert, reusable testing patterns, parametrization, fixtures, test organization, code coverage, continuous integration, and professional testing practices.

Rather than treating testing as an afterthought, this book presents it as an essential part of software development.

Whether you are a Python developer, a student learning software engineering, or a developer moving from small scripts toward larger applications, this capsule gives you a practical foundation for writing software that is easier to maintain, refactor, and trust.

Learn the tools. Understand the principles. Build with confidence.

Practical engineering knowledge, one focused capsule at a time.

GitHub Actions for Python Projects is a practical, developer-focused guide to automating Python project workflows with GitHub Actions. Instead of treating CI/CD as abstract DevOps theory, this technical capsule focuses on the workflow concepts developers actually need when building and maintaining real Python projects. You will work through practical examples covering automated testing, code coverage, documentation builds, artifact generation, and deployment-oriented workflows. The goal is not simply to explain GitHub Actions, but to show how its components fit together into a reliable and maintainable automation workflow. You will learn: 1. How GitHub Actions workflows are structured 2. How to configure Python environments in CI 3. How to install and manage project dependencies 4. How to automate testing with pytest 5. How to generate and use test coverage reports 6. How to build project documentation automatically 7. How to upload and preserve workflow artifacts 8. How to organize jobs and steps effectively 9. How to design a practical workflow execution order 10. How to build reusable CI patterns for real Python projects Whether you are building a small Python project, maintaining an open-source repository, or moving toward a more professional CI/CD workflow, this capsule provides a concise and practical foundation for integrating automation into your development process. The focus throughout the capsule is on implementation, workflow design, and reusable engineering patterns rather than lengthy theoretical discussions. A compact technical guide for developers who want to move from manually running project tasks to building reliable, automated workflows with GitHub Actions.
