Learn Docker from scratch by containerizing Node.js & NestJS apps using Dockerfiles, Docker Compose, PostgreSQL
What you'll learn
Understand Docker fundamentals and build the correct mental model to confidently use Docker as a Node.js or NestJS developer.
Create Dockerfiles and containerize Node.js applications, including image building, container running, port mapping, and env variables.
Dockerize a real-world NestJS application using production-ready Docker strategies and environment configuration best practices.
Use Docker Compose to run multi-service backend systems locally with NestJS, PostgreSQL, Redis, networking, and volumes.
Requirements
Basic knowledge of jаvascript and Node.js is required. No prior Docker or DevOps experience is needed — everything is explained step by step.
Description
Docker has become a must-have skill for modern backend developers, yet most tutorials teach Docker from a DevOps or sysadmin perspective, leaving Node.js and NestJS developers confused, overwhelmed, and frustrated.This course is designed specifically for backend developers who want to use Docker confidently, not become infrastructure experts.You'll start by building the correct mental model of Docker — why it exists, what problems it solves, and how it fits naturally into a Node.js and NestJS development workflow. No unnecessary theory, no Linux deep dives — only what actually matters for developers.From there, you'll containerize a real Node.js application, write your first Dockerfile, understand every instruction line-by-line, build images, run containers, map ports, and manage environment variables correctly.Next, you'll move into real-world NestJS projects. You'll learn how to Dockerize a production-ready NestJS backend, handle .env files safely, differentiate between development and production Dockerfiles, and debug applications running inside containers.Finally, you'll master Docker Compose, allowing you to run multi-service applications locally — just like production. You'll connect NestJS with PostgreSQL and Redis, understand Docker networking, volumes, hot reloading, and environment separation.By the end of this course, you will:Understand Docker without fearConfidently Dockerize Node.js and NestJS appsRun full backend stacks locally using Docker ComposeAvoid common Docker mistakes developers makeBe job-ready for Docker-based backend rolesThis course focuses on practical skills, real projects, and developer clarity — not buzzwords.If you're a Node.js or NestJS developer who wants to finally understand Docker the right way, this course is for you.
Who this course is for
Node.js and NestJS backend developers who want to understand Docker clearly and use it confidently in real-world projects.
Backend developers confused by Docker tutorials made for DevOps engineers
Developers preparing for backend or full-stack job interviews involving Docker
Software engineers who want to run production-like environments locally
