Git submodules are actually a very beautiful thing. You might prefer the word powerful or elegant, but that’s not the point. The downside is that they are sometimes misused, so as always, use with care. I’ve used them in projects … Continue reading →
I had an itch to scratch, and I wanted to get a bit more familiar with Openshift. I had used it in the past, but it was time to have another go. The app and the code are now available. … Continue reading →
I just patched puppet-gluster and puppet-ipa to bring their infrastructure up to date with the current state of affairs… What’s new? Better README’s Rake syntax checking (fewer oopsies) CI (testing) with travis on git push (automatic testing for everyone) Use … Continue reading →
Seagate has just publicly announced 8TB HDD’s in a 3.5″ form factor. I decided to do some rough calculations to understand the density a bit better… Note: I have decided to ignore the distinction between Terabytes (TB) and Tebibytes (TiB), since … Continue reading →
Earlier this year, R.I.Pienaar released his brilliant data in modules hack, a few months ago, I got the chance to start implementing it in Puppet-Gluster, and today I have found the time to blog about it. What is it? R.I.’s … Continue reading →
Vagrant has become the de facto tool for devops. Faster iterations, clean environments, and less overhead. This isn’t an article about why you should use Vagrant. This is an article about how to get up and running with Vagrant on … Continue reading →
This is a quick trick for making working with git submodules more magic. One day you might find that using git submodules is needed for your project. It’s probably not necessary for everyday hacking, but if you’re glue-ing things together, … Continue reading →
I’ve been afraid of RPM and package maintaining [1] for years, but thanks to Kaleb Keithley, I have finally made some RPM’s that weren’t generated from a high level tool. Now that I have the boilerplate done, it’s a relatively … Continue reading →
Puppet is missing a number of much-needed features. That’s the bad news. The good news is that I’ve been able to write some of these as modules that don’t need to change the Puppet core! This is an article about … Continue reading →
I’ll be giving a talk at SCALE today about automatically deploying GlusterFS with Puppet-Gluster and Vagrant. I’ll be giving some live demos, and this will cover some of the material from: Automatically deploying GlusterFS with Puppet-Gluster + Vagrant! and it … Continue reading →
I needed a base image “box” for my Puppet-Gluster+Vagrant work. It would have been great if good boxes already existed, and even better if it were easy to build my own. As it turns out, I wasn’t able to satisfy … Continue reading →
The GlusterFS community is having a “test day”. Puppet-Gluster+Vagrant is a great tool to help with this, and it has now been patched to support alpha, beta, qa, and rc releases! Because it was built so well (*cough*, shameless plug), … Continue reading →
Puppet-Gluster was always about automating the deployment of GlusterFS. Getting your own Puppet server and the associated infrastructure running was never included “out of the box“. Today, it is! (This is big news!) I’ve used Vagrant to automatically build these … Continue reading →
Apparently lots of people are using Vagrant these days, so I figured I’d try it out. I wanted to get it working on Fedora, and without Virtualbox. This is an intro article on Vagrant, and what I’ve done. I did … Continue reading →
Ironically, one of the reasons that I started writing Puppet code, was so that I could spend more time designing and building, and less time writing documentation. I suppose I’m a victim of my success, because Puppet-Gluster has grown large … Continue reading →
Hi there, I hope you enjoyed my “Pushing Puppet (to its limit)” talk and demos from Puppet Camp D.C., LISA 2013. As requested, I’ve posted the code and slides. Here is the code: https://github.com/purpleidea/puppet-pushing This module will require three modules … Continue reading →
I’m speaking at LISA 2013, the “Large Installation System Administration” conference. This conference runs all week in Washington. I’ll be giving two talks during the week, and attending at least one BOF. My first talk is on Monday during the … Continue reading →
In my attempt to push puppet to its limits, (for no particular reason), to develop more powerful puppet modules, to build in a distributed lock manager, and to be more dynamic, I’m now attempting to build a Finite State Machine … Continue reading →
Theron Conrey writes about using: BitTorrent Sync as Geo-Replication for Storage We got a chance to talk about this idea at Linuxcon. I’m not entirely convinced there aren’t some problem edge cases with this solution, but I think it will … Continue reading →
I’m here in New Orleans hacking up a storm and getting to meet fellow gluster users IRL. John Mark Walker started off with a great “State of the GlusterFS union” style talk. Today Louis (semiosis) gave a great talk about … Continue reading →
