About the course

🐳 Package your application so it works everywhere — not just on your machine

«It works on my local» — the classic developer problem. Docker solves it for good: a container holds everything needed and runs identically on your Mac, your colleague’s machine and in the cloud. In this course you’ll containerize a real application and deploy it to the cloud.

In this course you’ll go from chaos to production in 5 lessons:
- First container: images, layers, basic Docker commands
- Dockerfile: building images, optimization, publishing to Docker Hub
- Docker Compose: multi-container app, networks, volumes
- Cloud deployment: Nginx, SSL, monitoring
- Advanced techniques: multi-stage builds, security, CI/CD

Stack:

docker · docker-compose · nginx · Docker Hub · CI/CD
