COURSE PREVIEWAbout this course
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.
What you'll learn
- Docker fundamentals: images, containers, layers, and what they actually mean
- Docker Compose: orchestrating multi-service applications
- Volumes, networks, healthchecks, and dependencies done right
- Hybrid local development: native speed for your app, containers for services
- Nginx as a reverse proxy: routing, headers, and proxy_pass
- Hosting multiple projects on one server with a shared edge gateway
- VPS setup: SSH, firewalls, security basics
- Domain configuration and DNS
- Free HTTPS with Let's Encrypt and certbot
- Deployment workflows that don't break things
Before you begin
- A computer (Mac, Windows with WSL2, or Linux)
- Docker Desktop or Docker Engine installed
- A code editor
- Basic skill of NodeJS but not required
Who this is for
- Developers
