Understanding Docker Containers

Docker containers have revolutionized software development by providing lightweight, portable, and consistent environments across different machines.

What is a Container?

A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.

Key Benefits

• Isolation: Containers run in isolated user spaces
• Portability: Works consistently across environments
• Efficiency: Shares the host OS kernel
• Scalability: Easy to scale up or down

Basic Commands

Here are some essential Docker commands:

    docker build -t myapp .
    docker run -p 4000:80 myapp
    docker ps
    docker stop container_id
