My Pythony Puppet Ruby Vim IDE

| Comments

Despite my penchant for tools written in Ruby (Puppet, Gitlab, Jekyll/Octopress etc) I do not actually like Ruby. I am more of a Python guy. I also like Vim, so whenever I use a GUI IDE I end up with something littered with :w and ZZ.

Super Slick Agile Puppet for Devops

| Comments

With a superb buzzword laden title like that, then I reckon massive traffic boost is inevitable.

Puppet is my favourite Configuration Management tool. This is not a post to try and persuade anyone not to use Ansible, Chef or any other. What I want to do is show I build Puppet based infrastuctures in such away that it meets all the basic tenets of DevOps/Agile/buzzword-of-the-month.

New Linux Active Directory Integration

| Comments

This used to be quite complex, but now is astoundingly simple. Now there is a new project call realmd. It is in recent version of Debian (Jessie and Sid) and Ubuntu (since 13.04). For Red Hat types, it is RHEL7 and Fedora (since 18).

Home-made Energy Bars

A break from computing today and into the world of nutrition. Cyclists love to talk about nutrition as the nature of our sport makes it a major consideration. I do not really know of any other sport where your fuel gives out before the rest of your body.

VMware CLI on Ubuntu Saucy Salamander

| Comments

Openstack Neutron Performance Problems

| Comments

For the last few weeks I have been consulting on a private cloud project for a local company. Unsurprisingly this has been based around the typical Openstack setup.

  • Nova - KVM
  • Neutron - Openvswitch
  • Cinder - LVM
  • Glance - local files

Logstash on CentOS 6

| Comments

It’s been a while since I last posted anything, but it is time to. I’ve been playing around a lot with various tools for gathering information about my environment recently. One of the most important tools for storing that information is decent logging. Syslog is proven and solid, but a little creaky. For storing everything it is fine, but getting anything out is not so great.

NFS With Puppet and an ENC

| Comments

Ages ago (it seems) I posted a howto on configure NFS using Puppet and Hiera. I have been using this happily for several months and adding a new share was is as simple as adding a line to a YAML file. I was never completely happy with it though, especially after I decided to deploy The Foreman in my lab.
