The document outlines Boyd Hemphill's experiences and insights regarding managing Docker applications in production environments, emphasizing the evolution of DevOps and the integration of Docker within development workflows. It discusses challenges like Docker tool maturity, deployment issues, and container sprawl, along with potential solutions for service discovery and telemetry. The roadmap for Docker management includes enhancements in service discovery, user management, and live product demonstrations.
StackEngine Problem Space Demo
- 1. Managing Docker Applications in Production Boyd E. Hemphill @behemphi @stackengine
- 2. History - Boyd Oracle Developer, MySQL DBA, PHP Developer, System Architect, DevOps Director (yea, really) Started Austin DevOps In 2012 Co-Organizer of DevOps Days Austin Became involved in Docker Austin in August. Working with Docker for the first Docker Days Austin Keep an eye on @stackengine to see if we can make it happen!
- 3. History - StackEngine CopperEgg Started in May 2014 to address problems arising due to Docker adoptions Funding announcement October Currently in private beta mike@stackengine.com

- 6. What is The Goal of Your Company? Make Money!
- 7. So … What is DevOps?
- 8. Is DevOps a Process?
- 9. Is it an intersection of overlapping concerns?
- 10. Is DevOps a Culture?
- 11. DevOps: DevOps is the way in which a technology organization embeds itself in a business to the benefit of that business.
- 12. The Ideal Docker Application
- 13. Netflix (unicorn) Service Oriented Architecture
- 14. Benefits Increase developer velocity using containers to model application topology Decrease build and test times using containers as build/test agents rather than VMs Density - Reduce Costs Separation of Concerns - “Code to an interface” moves to the infrastructure level Taken together a company that can get to the end state has a significant and lasting competitive advantage
- 16. Concerns This is still very early days for Docker Tools to support Dockerized applications immature or do not exist Service oriented architecture is hard Increasing developer is only a local optima, thus a false economy Its the first major DevOps initiative not driven by Ops.
- 17. SDLC Developers are moving forward QA sees production modeling and large test grids Build engineers see easier build grids Operations panics - no tools or instrumentation
- 18. The Final Mile
- 19. The Final Mile Developer uses containers System is built and images are produced Images stored in a private repo Now we need to deploy to a QA environment Umm ….
- 20. Docker Deployment Completing the final mile
- 22. Deployment Continuous Deployment was published in 2010 In general we still talk about build and integration, not deployment This is true for all applications, not just those that are Dockerized Docker promises A/B deployment StackEngine is working on making A/B deployment a policy based activity
- 23. Container Sprawl
- 24. Container Sprawl First there was VMware and suddenly a large corps departments could easily spin up environments Then there was the cloud and developers could complete circumvent Ops Now there is Docker and Developers are creating numerous abstractions that are not managed like traditional VMs Containers on VMs on phyical hardware located in availability zones in data centers in geographic regions.
- 25. My Head Hurts Container Sprawl
- 27. Where’s My Stuff Hosts
- 28. Where’s My Stuff Images
- 29. Where’s My Stuff Containers
- 30. Telemetry
- 31. Telemetry What does monitoring a docker app look like? What does log aggregation look like?
- 32. Telemetry Container size matters - blog Log aggregation solution - blog
- 33. What’s my stuff (not) doing Containers
- 34. What’s my stuff (not) doing Containers
- 35. What’s my stuff (not) doing Containers
- 36. Components
- 37. Components Components are infrastructure abstractions (cloud provider, data center, docker registry, docker image) Components can be arranged in logic ways to represent physical infrastructure.
- 38. Composing and App Components
- 39. Composing and App Components
- 40. Composing and App Components
- 42. Service Discovery - Consistency Models Zookeeper Etcd / Consul Chef Server / Heira
- 43. Service Discovery Due out in December Allows multiple deployments of the same service on the same host. Containers register themselves upon startup and are found by tags rather than URI’s, fixed ports, etc. A step towards cattle containers instead of pet containers
- 44. Roadmap
- 45. Roadmap Service Discovery User Management Addition of new Components Better telemetry Scheduling A/B Deployment support
- 46. Live Product Demo Al Gore and his gremlins willing
