📘 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

🙌 Thank You
Thanks to everyone who supported me while writing this — from colleagues and students to early readers. Writing a technical book in 2025 isn’t easy, but it’s rewarding when it helps someone build better systems.
Let’s keep shipping. 🚀
