6. How did we get there?

7. Docker in 2013
A lightweight runtime and robust tooling to build and run virtual containers on Linux to create the operating environment for your distributed applications.

8. Docker Basics Docker Image The basis of a Docker container
The standard unit in which the application service resides
Docker Engine
Creates, ships and runs Docker containers deployable on physical or virtual host locally, in a datacenter or cloud service provider
Docker Registry
On-premises registry for image storing and collaboration

9. Applications are changing
~2000
Today
Loosely Coupled Services
Monolithic
Rapidly updated
Slow changing
Many Small Servers
Big Servers

10. The challenge: new matrix from hell
Static Website
Analytics DB
User DB
Background Workers
Web Front End
API Endpoint
Queue
Development Test & QA Production Scale Out
Virtual machines
Disaster Recovery
Server Cluster
Developer Laptop
Server
Data Center
Public Cloud

11. Solution: Docker containers
Packages up software binaries and dependencies
Isolates software from each other
Container is a standard format
Easily portable across environment
Allows ecosystem to develop around its standard
Container

12. Solution: Docker containers
Background Workers
Analytics DB
User DB
Static Website
Web Front End
API Endpoint
Queue
Any App
Anywhere
Composable
Dynamic
Portable

13. Why do Developers Care? Build once…(finally) run anywhere
A clean, safe, hygienic and portable runtime environment for your app.
No worries about missing dependencies, packages and other pain points during subsequent deployments.
Run each app in its own isolated container, so you can run various versions of libraries and other dependencies for each app without worrying
Automate testing, integration, packaging…anything you can script
Reduce/eliminate concerns about compatibility on different platforms, either your own or your customers.
Cheap, zero-penalty containers to deploy services? A VM without the overhead of a VM? Instant replay and reset of image snapshots? That’s the power of Docker

14. Why do Ops Care? Configure once…run anything
Make the entire lifecycle more efficient, consistent, and repeatable
Increase the quality of code produced by developers.
Eliminate inconsistencies between development, test, production, and customer environments
Support segregation of duties
Significantly improves the speed and reliability of continuous deployment and continuous integration systems
Because the containers are so lightweight, address significant performance, costs, deployment, and portability issues normally associated with VMs

15. Containers vs. VMs

16. Birthday App Training

17. Docker Platform Everything you need to get started with Docker
Docker for Mac
Docker for Windows
Docker for Linux

18. Birthday App Training
Participants in the training will go through the steps involved in running and developing a simple voting app from a fresh computer using Docker Toolbox. This simple app will include:
A Python webapp which lets you vote between several options
A Redis queue which collects new votes
A Java worker which consumes votes and stores them in…
…A Postgres database backed by a Docker volume
A Node.js webapp showing the results of the voting in real time
All training materials available at:
There is a self-paced beginners’ tutorial for attendees to learn Docker basics as they build and deploy this app locally and push their Docker images to Docker Hub. Experienced Docker users will serve as mentors to help beginners successfully complete the training.
ask mentors to raise their hands

19. Birthday App Challenge

20. Birthday App Challenge Ideas
For Devs
Rewrite or add features to the following apps:
Python webapp which lets you vote between two options
Java worker which consumes votes and stores them
Node.js webapp which shows the results of the voting in real time
Write something to generate random votes so they can load test their app
For Ops
Bring Docker Swarm in the mix
Add Interlock:
Scale out the worker nodes using Docker Cloud
