This document provides an introduction to Docker. It discusses why Docker is useful for isolation, being lightweight, simplicity, workflow, and community. It describes the Docker engine, daemon, and CLI. It explains how Docker Hub provides image storage and automated builds. It outlines the Docker installation process and common workflows like finding images, pulling, running, stopping, and removing containers and images. It promotes Docker for building local images and using host volumes.

• docker build # Build an image from a Dockerfile
• docker images # List all images on a Docker host
• docker run # Run an image
• docker ps # List all running and stopped instances
• docker stop # Stop a running instances
• docker rm # Remove an instance
• docker rmi # Remove an image

11. Docker Architecture

12. Docker Hub
• Provides Docker Services
• Library of public images
• Storage for your images
• free for public images
• cost for private images
• Automated builds(link github/bitbucket repo; trigger
build on commit)
