New Script – Install Puppet on CentOS

As I’m now using Puppet also with CentOS I’d like to share the script I use to install Puppet on my CentOS VM. The script installs Ruby as well since you need it to run Puppet.

At the moment I’ve been using Puppet on CentOS without a puppetmaster so it’s properly tested only as serverless Puppet, but there’s shouldn’t be any problems even if you’re using a puppetmaster. I’m actually combining the use of Fabric and serverless Puppet to do some quick tests on multiple virtual machines but maybe I’ll write a bit about that in another post some day. Anyway, here’s the script: Read more of this post

Script for adding multiple Vagrant boxes

I’ve been using Vagrant for a while now to test new configurations with simple virtual machines. Usually it’s just a single VM that I’m using but now I wanted to do some tests on more than one machine at the same time.

So I was looking for a way to easily create multiple identical virtual machines with Vagrant but couldn’t find a good solution so I made this small script to do it for me. If you know a better way, could you leave a comment and then we can both laugh at this script. I have also included a guide for controlling these new VMs with Fabric.

The script copies a packaged vagrant box as many times as you define and adds them to vagrant. Then adds the new virtual boxes to the Vagrantfile config. These new vagrant machines have hostonly static IP network setting but you can change it to bridged in the script if you want IPs from DHCP. The hostonly means that the machines can only be accessed from the host machine that’s running vagrant.

If you want to use multiple vagrant boxes without the script, here are the steps:
Create a single Vagrant box. Guide
Package it. Guide
Copy the package.box file. You need a copy for each virtual box. Guide 😉
Add the new box copies to vagrant. Guide
Add new config to Vagrantfile for each new box. Guide
Start the boxes with ‘vagrant up’

And here’s the guide for using my script:
