1. Serverspec The Simplest Server Testing Tool Ever #ChefConf 2014 Gosuke Miyashita
2. Let me introduce myself

4. Freelance software engineer
7. Chef in Japan
9. What is serverspec ?
11. “RSpec tests for your servers configured by Puppet, Chef or anything else.”
15. cgroup/command/cron/ default_gateway/file/group/host/ iis_app_pool/iis_website/interface/ ipfilter/ipnat/iptables/kernel_module/ linux_kernel_parameter/lxc/ mail_alias/package/php_config/port/ process/routing_table/selinux/service/ user/windows_feature/ windows_registry_key/yum_repo/zfs
16. See: serverspec.org/ resource_types.html
17. RedHat/CentOS/SuSE Debian/Ubuntu Arch/Gentoo/Plamo AIX/Solaris/SmartOS FreeBSD/Mac OS X MS Windows
18. How to work ?
19. Run commands, simply via local/SSH/WinRM
20. Detect OS automatically and Run suitable command
23. Change local/SSH/ WinRM by including appropriate helper
24. OS Detection Helper #BDLFOE Helper
25. What is SpecInfra ?
26. SpecInfra is a command execution framework separated from serverspec
27. SpecInfra serverspec DSL by RSpec Call specinfra API API … OS Abstraction Layer (OS Helper) Commands for Linux Commands for Debian Commands for Solaris Commands forWindows Backend Abstraction Layer (Backend Helper)
28. ? Why I separated into serverspec and specinfra
29. I’ve created a very simple configuration management tool as a proof of concept
30. serverspec/configspec
33. You can create Another type of serverspec with SpecInfra easily
34. But higher abstraction brings more complexity …
35. Why I started this project ?
36. I’m heavy Puppet user since 2007
37. My old puppet manifests are not fully modularized
38. I’ve decided to refactor my puppet manifests
39. Refactoring needs test code
40. But there are no testing tools meet my needs
41. So I made my own testing tool
42. Philosophy "
43. Simpleness
44. Easy to use
45. Support Ruby 1.8.7 (Because for supporting RHEL/CentOS)
46. No need other than Ruby
47. Even Ruby is not needed with SSH
48. Independent from any configuration management tools
49. I love the UNIX philosophy, KISS principle
50. Advanced Topics "
51. How to Customize ?
52. serverspec.org/advanced_tips.html github.com/serverspec/examples
53. Combination with other tools
54. Serverspec is simple and agnostic
55. Test Kitchen
56. busser-serverspec
57. See: kitchen.ci/docs/ getting-started/ writing-server-test
58. Vagrant
59. vagrant-serverspec
61. See: github.com/ jvoorhis/vagrant- serverspec
62. Caution "
64. Integration test of serverspec itself
65. serverspec/serverspec- integration-test
66. Wercker + DigitalOcean
67. # 1. Pull code 2. Create machines 3. Run Chef and tests 4. Get result
69. Now only support CentOS 6 and a few serverspec test code
70. So now I’m working on increasing OS and test code
