This document provides an overview of Docker including why Docker is useful, how the Docker platform works, and common Docker workflows. It discusses Docker's isolation, lightweight virtualization, simplicity, community support, and installation process. Key Docker concepts covered include images, containers, the Docker Engine, Docker Hub, and using volumes. The document demonstrates common Docker commands and workflows like building, running, and sharing images.

2. Agenda
• Why Docker?
• Docker Platform
• Docker Installation
• Docker (Basic Image) Workflow
• Docker (Build) Workflow
• Docker (Volumes) Workflow

3. Why Docker?
• Isolation
• Lightweight
• Simplicity
• Workflow
• Community

4. Docker Community
• 21,500+ GitHub stars
• 400M+ Docker Engine downloads
• 100,000+ "Dockerized" applications in the Docker Hub Registry
• 180+ Docker Meetup Groups in 50 countries
• 930+ community contributors
• 3 to 4 Million - Developers using Docker
• 50,000 third-party projects on GitHub using Docker as well as
partnerships spanning PaaS, operating systems, hosting
services, CI platforms, and more.
• Over 100 user-generated case studies available from
companies such as eBay, Rackspace, New Relic, Gilt, Spotify,
Cloudflare, Yandex, Cambridge Healthcare, Yelp and RelatelQ.

5. Docker Engine
+ Docker Hub
= Docker Platform

6. Docker Engine
• Docker Daemon
• Builds Images
• Manages Containers
• RESTful API
• Docker CLI
• Command Line Client

7. Docker Architecture

8. Docker CLI
• 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

9. Docker Hub
• Provides Docker Services
• Library of public images
• Storage for your images
• free for public images
• cost for private images
• Automated builds

10. Docker Hub

11. Docker Installation

12. Docker Installation

13. Docker (Basic Image) Workflow
• Find an Image on Docker Hub
• Pull an Image from Docker Hub
• Run an Image on Docker Host
• Stop an Instance
• Remove an Instance
• Remove an Image

14. Docker (Basic Image) Workflow

15. Demo

16. Docker Run Command Basics

17. Docker (Build Image) Workflow
• Build a Local Image
• Run an Image on a Local Docker Host
• Push an Image to Docker Hub
• Pull and Run on another Docker Host
