Containerization platform

Packages an app and all its dependencies into a container, ensuring it runs the same in every environment.

• Fix “Works on my machine” problem
  • No need manual setup for each machine/server
  • Fix env mismatch (OS, libraries, versions)
  • Same image → same behavior everywhere
• Lightweight compared to virtual machines
• Fast startup & consistent deployments

Architecture Flow

Dockerfile
   ↓ build
Docker Image
   ↓ run
Docker Container
   ↓ push/pull
Docker Registry (Docker Hub)

1. Write app code
2. Write Dockerfile
3. Add .dockerignore
4. Build image
5. Run container locally
6. Use docker-compose for dependencies
7. Push image to Docker Hub
8. Pull image on server
9. Run container in production
