- 16. The path toDocker
- 17. The path toDocker 17 Use case : • Linux : How to run « ls –l » ? • Our tools : How to validate a « managed service » ? • Network and clusters : How to validate when my app scales ?
- 18. The path toDocker • Linux on Windows 7 : VirtualBox ! • Manage and share VMs : Vagrant ! • Provision your VMs : Shell or Chef !
- 19. The path toDocker Remember ?
- 20. The path toDocker With that stack :
- 21. The path toDocker Another problem : the learning curve
- 22. The path toDocker So why not Docker ? • It’s fast (start & cache) • It’s reproducible • It’s easy to launch bunch of stuff
- 23.
- 24. Problems ? Solutions! How to run a Docker daemon on Windows ? • Stayin’ with Virtualbox • The lightweight VM as possible • Ready for dev
- 25. Problems ? Solutions! Boot2docker : • 30 Mb • Docker up-to-date and ready • VirtualBox ready
- 26. Problems ? Solutions! How to reuse already made things ? • Maintain already known workflow • Easily share folders from Windows • Limit configuration effort (proxy, certificates, persistence)
- 27. Problems ? Solutions! Vagrant + dduportal/boot2docker : • Vbox shared folder • Provisioning • « vagrant-proxyconf » plugin
- 28. Problems ? Solutions! How to provision the stack ? • Dev. don’t care • Dev. use Maven : describe • Dev. want ops stuff and their stuff
- 29. Problems ? Solutions! Fig • YAML text-based : shareable • Hierarchy : intentional description • Image or build your services
- 30. Problems ? Solutions! You said « run anywhere » ? • Use of private IaaS (thru vagrant plugin) • Env. differences (local / remote) • Fig isn’t full-statically compiled (no b2d, no busybox)
- 31. Problems ? Solutions! dduportal/fig Docker Image • Debian-based • Embeds a working fig • Needs to share Docker socket • Won’t be needed when ‘docker groups’
- 32. Problems ? Solutions! We got a blueprint ! Vagrant VirtualBox Private Sandbox IaaS Boot2docker VM Boot2docker VM Blueprint dduportal/fig My App Stack docker

- 40. The « Humanstack » Solomon Hykes – SF DockerCon 2014 : « The real value of Docker is not technology, it’s getting people to agree on something»
- 41. The « Humanstack » Docker is the « bottom-up » for devops. I learned 2 things with that tool : • It helps people communicate better : we can work and share humanly • It creates a learning context : people can see the value of their jobs
- 42. Docker makes technology « human centric » It’s true DevOps
- 43. @people around Docker: you’re awesome !

Editor's Notes
- #42 Look at me : why am i here telling you those things ? Because Docker makes me listen, learn, communicate, and share !
