Ops for Everyone

At GitHub, system administration is a first class citizen. Changes are collaboratively developed, peer reviewed, revision controlled, and ship with tests. Automation isn't just for production; we apply the same techniques to our individual developer workstations. In this talk, I'll give you a sneak peek into how a GitHub developer experiences Ops. We'll start with setting up a new machine using Boxen and jump right into the specifics of how to deploy and ship a new feature using the "ChatOps" shared command line. I will show you how we deploy configuration changes to individual and groups of hosts. We'll finish up with a look at how GitHub instruments application performance and exceptions to make it easy to spot newly introduced issues.

2.  johndbrion
3. I THOUGHT OPS WAS JUST FOR NECKBEARDS I WAS WRONG
4. FIRST PRINCIPLES:
5. COLLABORATION
6. AUTOMATION
7. EXPERIMENTATION
8. DISTRIBUT-ATION?
9. HOW DO WE DO IT?
10. BOXEN
11. HUBOT
12. BOXEN
13. ELIMINATE FRICTION BOXEN MAKES IT POSSIBLE TO BUILD SOMETHING MEANINGFUL ON DAY ONE
14. DAY ONE
15. INSTALL XCODE COMMAND LINE TOOLS
16. $ curl -s https://example.com/script/boxen.sh > /tmp/ install-boxen; bash /tmp/install-boxen | sh
17.  GRAB A BEVERAGE
18. HOMEBREW, GIT, GCC, .DEV DNS, NGINX, RBENV, RUBY-BUILD, MANY RUBIES, NODENV, MANY NODES, HEROKU TOOLCHAIN, HUB, MYSQL, POSTGRESQL, ELASTICSEARCH, RIAK, JAVA
19. $ boxen github
20. YOU’VE GOT GITHUB, NOW GO WRITE SOME CODE
21. PROJECT MANIFEST
22. class projects::education-web { github::project { 'education-web': dotenv => true, elasticsearch => true, redis => true, ruby => '1.9.3-p231-tcs-github', postgresql => [ 'education_web_development', 'education_web_test' ] } }

31. IT’S JUST PUPPET, FOR YOUR MAC
32. HUBOT
33. SHARE THE TERMINAL HUBOT MAKES IT POSSIBLE TO TEST, SHIP, AND MEASURE EVERYTHING
34. CHATOPS
35. NOBODY CAN SEE WHAT COMMANDS ARE RUN ON THE TERMINAL
36. IT’S HARD FOR NEW HIRES TO FIGURE OUT HOW TO DEPLOY
37. THINK OF CHAT AS A SHARED COMMAND LINE
38. CHATOPS SURFACES OPERATIONS THAT WOULD OTHERWISE BE INVISIBLE
39. NEWCOMERS LEARN BY WATCHING EXPERIENCED USERS
40. TEST
41. /CI BUILD
44. SHIP
45. /CONFIG
48. /DEPLOY
50. /HOSTS
52. /PUPPET RUN
54. MEASURE
55. /GRAPH ME
58. FUN COMMANDS
59. /WHERE IS
62. /FITBIT ME
64. /NEW HIRE ME
66. /ANIMATE ME
