In this talk we review what Docker is and why it's important to Developers, Admins and DevOps. We also cover the following topics: - Using Docker to Orchestrate a multi container application (Flask + MongoDB) - Injecting HAProxy and other production requirements as we deploy to production - Scaling the Web and MongoDB cluster to grow to meet demand This presentation includes an interactive demo showcasing the core Docker components (Machine, Engine, Swarm and Compose) as well as some of Docker's new components (libnetowrk, runC) from the experimental branch along with MongoDB. We hope you will see how much simpler Docker can make building and deploying multi-node applications. <hr> <b>What's next?</b> See how you can push MongoDB performance to meed the needs of your mission-critical app with our best practices for MongoDB operations. <a>Read the guide</a>

5. Open Container Initiative (OCI)
Coalition of industry leaders join forces to eliminate fragmentation
• Form a vendor-neutral, open source governance model under the Linux
Foundation
• Establish common standards for container format and runtime
• Docker donated its container format, runtime and associated specifications
• Appoint maintainers for the libcontainer project

• Container SDN
• Distributed networking
• Portable across networks
• Plug ins to broad ecosystem

8. Plugins
Pluggable Architecture to extend Docker functionality
• Introducing Networking and Volume plugins
• For Users: Portability and choice for developers and ops
• For Partners: Easily integrate and access Docker users
• Collaboration with Cluster HQ, Glider Labs, Weave

17. Part Two: Development through to Production
• Build & Run an App in Development
– Python + MongoDB
• Deploy to a Swarm cluster in Production
– Scale Web services
• Deploy new MongoDB Cluster in Production

27. Storage: Inside or outside the container?
Inside
• Encapsulation of Concerns
29
Host
daemon
container
Host
daemon
container e.g.
SSD
e.g.
EBS
Outside
• Separation of concerns
• Storage Features (e.g. snapshots)
/data/db
/mnt/xx:/data/db

28. Summary
• Define

their

they
work

• Ops

• Dev
