Introduction to Docker

Docker is a platform for developing, shipping, and running applications using containers.

What are Containers?

Containers package an application with all its dependencies, ensuring it runs consistently across different environments.

Basic Docker Commands

docker build -t myapp .     # Build an image
docker run myapp            # Run a container
docker ps                   # List running containers
docker stop <container>     # Stop a container

Benefits

• Consistent environments
• Easy deployment
• Resource efficiency
• Isolation between applications

Docker simplifies application deployment and management.
