12 months of Production Time with Docker

Docker is fast, deterministic, and delivers really well on promises, but it’s just a small piece of the puzzle. This talk is about the other missing pieces for a successful production environment run entirely in Docker containers, on dedicated hardware, with no PXE magic.

Talk given at the first Docker conference in London, Container Camp, 12 September 2014

1. 12 months of Production Time with
2. Production Always raw hardware for best performance.
3. Staging Raw hardware for quick feedback loops.
4. Fast. Repeatable. Easy.
5. Fast. Repeatable. Easy. But it only solves 1 problem well, as all real Unix tools do.
6. [x] Gerhard [x] Platform
7. [x] Gerhard [x] Platform
8. WWGD? Does things as I would do them: in a shell, over SSH.
9. Declarative nature Easy to follow & debug
10. Thin abstractions Fast feedback
11. Batteries included Point and... play!

19. $ which gp > aliased to git push $ which d > aliased to docker $ which dr > aliased to docker run
20. The Gerhard Platform Simple solutions to production Docker challenges
21. $ which gp > aliased to git push $ which d > aliased to docker $ which dr > aliased to docker run
22. Image management dr registry localhost:5000/nginx:1.6.1
23. Service dependencies ansible-playbook runsv
24. Container supervision dr --restart runsv
25. Log management dr -v /mnt/log/nginx svlogd
26. Raw network I/O dr --net host
27. Raw disk I/O dr -v /mnt/mysql LVM... with snapshots o.O
28. Service discovery dr -p 127.0.0.1:60000:3000 SO_REUSEPORT
29. Service discovery dr -p 127.0.0.1:60000:3000 SO_REUSEPORT
30. Firewall dr -p 127.0.0.1::3306 iptables & ferm
31. Config templating dr -v /opt/nginx/conf pkill -HUP -f nginx.*master
32. App runtimes localhost:5000/ruby:2.1.2 dr -v /mnt/[app]
33. Monitoring dr --privileged New Relic & Linode Longview
34. Sysadmin tools dr --privileged htop, ntop, iptraf, dstat, vnstat ...
35. The Gerhard Platform Just how fast is it? Very.
36. The Gerhard Platform Just how fast is it? Very
37. 5 minutes 14.04 base provision
38. 10 minutes Cold production setup
39. 2.5 minutes Warm production setup
40. 15 minutes Re-create production
41. Thank you Docker For enabling my next generation Gerhard Platform
42. Thank you Ansible For letting me learn and iterate quickly, even in production
43. Perfect software is the one that you don't know well enough.
