Topic: "Safer Puppet" in 4 quick demos
Speaker: Thomas Limoncelli
Date: Thursday, May 7th, 2015
Time: 7:00pm (social), 7:30pm (discussion)
Nervous about making big changes to your systems with Puppet? Tom will present 4 techniques we use at Stack Exchange, Inc. that will increase your confidence in the changes you make using Puppet.
• Infinite source code "undo" using Git
• Automatic testing and deployment using TeamCity
• Build a test environment on your laptop using Vagrant
• Test changes in production safely using Puppet Environments and --noop
If the WiFi is working, Tom will make live changes to Stack Exchange, Inc's infrastructure during the presentation.
