Central Ohio Linux User Group
Date: Wednesday, October 21 2015, 7 - 9 PM EDT


Have you ever committed code only to discover later that it does not actually work in production the way you think it should? When is the last time you wanted to test a new version of a dependency but worried it would wreck your existing setup if it goes wrong? Have you ever wanted to run `rm -rf /` on a running machine just to see what happens?

Vagrant is a tool to quickly spin up virtual machines ready to run your code. This gives you the freedom to test potentially hazardous changes while still being able to easily revert to a known-good configuration. In this session, you will learn the Vagrant workflow, including how to give all of the developers on your team an environment that matches production, so that you will never have to hear the 'But it Works on My Machine' excuse again.

The first 2/3 of this talk will be a reprise of the talk of the same name given at the 2015 Ohio LinuxFest, however we will be able to dive into more examples and features during this talk due to the extra time available at COLUG.

About the speaker

A graduate of The Ohio State University, Joe (Beard?) is a JVM developer that enjoys using tools such as Hadoop, HBase, and Storm to solve complex problems with data. Joe is also a stylophile (one who appreciates fine writing implements) and a coffee aficionado.

The upcoming meeting is open to the general public, and all with an interest in Linux, Free Software, Open Source Software, Windows, BSD, Unix, OS X, SELinux, virtualization, development, Raspberry Pi, firewalls, WiFi, security, etc.

As always, feel free to bring with you any ailing or problematic systems for expert diagnosis (or destruction).

There are no dues or fees.


The meeting will be held at:

2 Miranova Place
Columbus, OH 43215

Orange section in parking garage

NOTE: please RSVP to Scott Merrill <skippy at> so that the correct number of parking vouchers can be secured.

Please park in the Orange section of the parking garage, which is specifically for guest parking. Parking in any other spot runs the risk of taking someone’s assigned parking spot. There is little risk of doing so at 7 PM, but why risk causing any trouble? Please park in the orange section. We will have parking vouchers so you do not have to pay to park if you RSVP'd to Scott Merrill <skippy at>.


On-street parking is available at meters. I do not know how late they are enforced. We are in the Car2Go service area, so Car2Go users can park at nearby meters for free.

Check in at the front desk, and then take the elevator to the 11th floor.

Thanks to CoverMyMeds for hosting us! They're hiring all sorts of technical folks, check out their job postings and tech blog ScriptScribe.
