Docker for Developers: From Zero to Production Deployment

Tired of Docker tutorials that stop at "hello world"? This course is built for developers who want to actually ship, not just understand containers in isolation.

By the end of this course, you'll have deployed a multi-service application to a real server, accessible at your own domain over HTTPS. Not a toy project, a real-world stack with a Next.js frontend, Express API, BullMQ worker, Postgres, Redis, and nginx as a reverse proxy.

This course is designed for working developers — not DevOps engineers, not SREs, not infrastructure specialists. If you write code for a living and want to understand the deployment side of your job, this is for you.

You should know:

- A backend language (Node.js examples, but concepts transfer)

- Basic command line

- What HTTP, JSON, and a database are

You don't need to know:

- Linux administration

- Networking deep-dives

- Kubernetes or any orchestration

- Production operations theory

WHAT YOU'LL BUILD

You'll containerize and deploy a real multi-service application with:

- Next.js frontend rendering pages

- Express API serving data

- Background worker processing jobs (BullMQ)

- PostgreSQL for persistent storage

- Redis for caching and job queues

- nginx as a reverse proxy with HTTPS

- A shared edge gateway pattern for hosting multiple projects on one server

By the final lesson, your app will be live at your own domain with a real TLS certificate from Let's Encrypt.

WHAT MAKES THIS COURSE DIFFERENT

Most Docker courses teach you what containers ARE. This course teaches you how to USE them in your daily work. Every lesson is anchored in a real problem you'll hit on the job.

- Pain-driven explanations: every concept starts with a problem you'd  actually encounter, not a feature list.

- Practical-first: no Kubernetes, no theory dumps, no abstract architecture. You'll write Dockerfiles and Compose files for real apps from lesson one.

- Honest about tradeoffs: when there are multiple ways to do something, you'll see them all and learn when each fits.

- Real production deployment: the course ends with your app live on the internet, not on localhost.
