  21. Building a Gem

  22. Right Tool Packages • Something that does not change often • Don't need to roll back quickly • Don't need more than 1 version at a time • You cache external repos or limit to just yours

  23. Right Tool Gems • Fast roll back – gem cache • Easy setup of gem server • Need more than 1 version at a time • Bundler for dependencies • Bundle exec for peace of mind

  24. Configuration Management • Puppet everything from bare metal/base image • Seperate data from manifests with an ENC • Max troubleshooting time is 20 minutes • Amazon free ”chaos monkey” service

  25. Puppet – Start with a sane base

  26. ENC – Use Groups! http://docs.puppetlabs.com/guides/installing_dashboard.html

  27. ENC – Node Entries Inherit

  28. ENC – Scripting Additions

  29. ENC - Output

  30. Manifests Contain ENC Variables

  31. Templates Contain ENC Variables

  32. Puppet - Tips • Execs hurt – try to avoid them • Recursive directories – use vcsrepo instead • Write your own types – just restart in between • Run mongrel or passenger • Use behind a load balancer for fun • Use reporting, but take the DB off of your master • Write your own facts and save lots of time

  33. Puppet - Scaling

  34. Mcollective – Do It NOW!! • Orchestration framework • Crazy Parallel • Write more ruby code... • Clients and Agents

  35. Mcollective – Crazy Parallel 6380 nrpe checks across 370 hosts in 3.8 seconds https://github.com/maguec/devops/tree/master/mcollective/nrpe

  36. Use Facts and Classes to Filter

  37. Mcollective – Custom Agent

  38. Mcollective – Custom Client

  39. Mcollective - Tips • Remeber you have a machine gun pointed at your foot • Wrap command in IO.popen and log everything • Log to syslog • Use ApacheMQ • For EC2 tune your keep alives (registerinterval) • Remember you have a machine gun pointed at your foot

  40. Mcollective - Scaling

  41. Sinatra • Web app in 5 minutes • Much more minimal than rails • Written in Ruby so I can interface with Mcollective easily http://www.sinatrarb.com/

  42. Sinatra – Addons • sinatra-respond_to - useful as API • Pony – send email from Sinatra • Twitter Bootstrap – make things pretty

  43. Public Example https://github.com/maguec/mco_dashboard_example

  44. Public Example

  47. Actual Push Procedure

  48. Dashboard Functionality • Push software • Audit software • Real-time monitoring check • Performance data integration • Log data integration • Troubleshooting tools for developers • Utilities for non-technical staff • Open trouble tickets • Cost information (in progress) • Userful links to other data sources
