📘 Mastering Docker from Scratch to Scale – A Hands-On Guide with Labs, CI/CD, Security & DCA Prep

Hey Dev.to community! 👋

I’m Sudipta Biswas, a cybersecurity architect and author. Over the past year, I’ve been building what I wished existed when I started working with containers and DevOps pipelines: a complete, lab-driven, real-world Docker book.

That effort turned into my latest release:

Mastering Docker from Scratch to Scale

If you're a developer, SRE, DevOps engineer, or certification aspirant, this might be the most hands‑on Docker book you'll pick up this year.

🔍 Why I Wrote This Book

Most Docker tutorials are:

Either too basic (just docker run)
Or too theoretical (no CI/CD, security, or monitoring)
And lack any structured, real‑world lab experience

I wanted something better:
✅ Step‑by‑step guidance

✅ Security best practices

✅ Modern CI/CD pipelines

✅ Production‑readiness

✅ Certification‑focused (DCA)

✅ And most importantly — Hands‑on Labs from Day 1!

So I wrote this book as a practical roadmap — from total beginner to Docker pro.

🚀 What’s Inside?

🧱 Part I: Foundations

Docker architecture, installation, CLI
Working with images, containers, networks, and volumes

⚙️ Part II: Intermediate to Advanced

Docker Compose and Swarm (with HA setup)
CI/CD with GitHub Actions
Monitoring with Prometheus, Grafana, cAdvisor

🔒 Part III: Security & Scaling

Docker hardening (user namespaces, AppArmor, seccomp, rootless mode)
DevSecOps workflows (SBOM, Docker Scan, malware sandboxing)
Resource limits, auto‑scaling, production deployment blueprints

📚 Bonus:

50+ hands‑on labs (linked to GitHub)
DCA practice questions with answer rationales
Real‑world case studies (e‑commerce, malware scanning, backup automation)
GitHub CLI and DockerHub CLI cheatsheets
Glossary of 100+ Docker & DevOps terms

💡 Who It’s For

This book is ideal for:

🧑‍💻 Developers who want to containerize projects cleanly
👨‍🔧 SREs building infra pipelines and scaling systems
🔐 Security pros adding Docker hardening and SBOMs
🎓 Students preparing for the Docker Certified Associate (DCA) exam
🏢 Teams adopting DevSecOps practices
