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.

Docker Engine
• Docker Daemon
• Docker CLI

9.
Docker Daemon
• Builds Images
• Runs and Manages Containers
• RESTful API

10.
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

11.
Docker Architecture

12.
Docker Platform Workflow
(Volumes)

13.
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)

14.
Docker Hub

15.
Docker Solutions
• Docker Compose
• Docker Machine
• Docker Swarm
• Kitematic
• Docker Networking
• Docker Trusted Registry

16.
Docker Compose

17.
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)

18.
Docker Swarm
• Discovery Services
• Advanced Scheduling
• API

19.
Docker Networking

20.
Docker Networking
“We'll do for Networking,
What Docker did for
Compute.”

21.
Docker Networking
• Make “network” & “service” as top-level objects
!
• Provide a pluggable networking stack
!
• Span networks across multiple hosts
!
• Support multiple platforms

22.
Container Network Model
(CNM)
• Endpoint
!
• Network
!
• Sandbox

23.
Libnetwork
• Open Sourced in April
!
• Over 200 Pull Requests
!
• Over 200 GitHub Stars
!
• Windows and FreeBSD ports in progress
