All of the posts on orchestration on here have been about Puppet on CentOS however last week I had need to script an AWS architecture and then launch instances built with Packer↗ into it. After much swearing I managed to hack together a python script which used Boto↗ to create a launch configuration and register it with an auto-scaling group, I then used a second script which re-cycled instances behind the Elastic Load Balancer which were launched with the previous launch configuration....

Yesterday, I had day out of the office with Danny↗ at the 2014 London PuppetCamp↗ . It was the first time I had attended a PuppetLabs event, though I have streamed plenty of video from past camps and conferences. It was interesting to see how best practices had moved on (answer, lots) since I first had my Puppet epiphany over a year ago. For me, and in no order, the most interesting talks were …....

Having ran a local copy of OpenShift Origin↗ using VirtualBox↗ I decided to have a go at running it on a Digital Ocean↗ Droplet running CentOS 6.5. This should be easy as there is an installer↗ which claims; You’re one shell command away from deploying your own Platform as a Service.

Think of it as strace + tcpdump + lsof + awesome sauce. With a little Lua cherry on top. It’s easy to install↗ ….

I have been playing my Digital Ocean↗ server a lot recently. Breaking it, fixing it and then rebuilding it, while I had documented my puppet installation it was getting to be a pain to copy and paste with each rebuild, so I pulled together a few scripts↗ from various sources to make the rebuilds a little less of a chore. To install fresh Puppet Master all I need to do now is run the following command;...

Vagrant allows developers to bring up local development machines in a controlled method using pre-built configuration files called boxes. Once a box has been installed on the developers local machine it can be powered on with the following command; Vagrant & Puppet 1/2 vagrant up When the box is brought up it automatically provisions itself using a number of provisioners including Puppet, this means that the production deployment scripts can also be run on local development copies of the instances....
