This file provides an introduction to Docker and how to get started with it.

What is Docker?​

Docker is a containerization platform that allows you to package applications and their dependencies into lightweight, portable containers.

Key Concepts​

  • Containers: Lightweight, standalone packages that include everything needed to run an application
  • Images: Read-only templates used to create containers
  • Dockerfile: Text file containing instructions to build a Docker image
  • Docker Compose: Tool for defining and running multi-container applications

Basic Commands​

# Pull an image
docker pull nginx

# Run a container
docker run -d -p 80:80 nginx

# List running containers
docker ps

# Stop a container
docker stop container_id

Getting Started​

  1. Install Docker on your system
  2. Verify installation: docker --version
  3. Run your first container: docker run hello-world
  4. Explore Docker Hub for available images
