This document provides an introduction and overview of Docker. It discusses why Docker is useful for isolation, simplicity, and workflow. It also covers the Docker platform, including the Docker engine, images, containers, and networking. Key components are the Docker daemon, Docker CLI, and Docker Hub registry. Demos are provided on installing Docker and using Docker for building images, running containers with volumes, and configuring Docker networking.

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

6. Killer Apps
• Local Application Development and Test
• CI/CD
• Containers as a Service
• Build your own Pass

7. 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
• 150,000 live apps are running off Docker
• 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.

9. Docker Engine
• Docker Daemon
• Docker CLI

10. Docker Daemon
• Builds Images
• Runs and Manages Containers
• RESTful API

11. 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

12. Docker Architecture

13. Docker Platform Workflow
(Volumes)

14. 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)

15. Docker Hub

16. Docker Solutions
• Docker Compose
• Docker Machine
• Docker Swarm
• Kitematic
• Docker Networking
• Docker Trusted Registry

17. Docker Compose

18. Docker Machine
• Install Docker on a Host
• Starting, stopping, restarting the Docker Engine
• Upgrading Docker on a Host
• Configuring the Docker client to talk to your host
(TLS)

19. Docker Swarm
• Discovery Services
• Advanced Scheduling
• API

20. Docker Networking

21. Docker Networking
“We'll do for Networking,
What Docker did for
Compute.”

22. Docker Networking
• Make “network” & “service” as top-level objects
!
• Provide a pluggable networking stack
!
• Span networks across multiple hosts
!
• Support multiple platforms

23. Container Network Model
(CNM)
• Endpoint
!
• Network
!
• Sandbox

24. Libnetwork
• Open Sourced in April
!
• Over 200 Pull Requests
!
• Over 200 GitHub Stars
!
• Windows and FreeBSD ports in progress
