Puppet Apprentice

Puppeteer

As I move my career towards the world of DevOps and automation / orchestration, I feel I need to learn the latest tools of trade for these fields. So, to that end, I'm installing the free version of Puppet Enterprise as a proof of concept. I've heard many people tell me how fantastic a tool Puppet is but haven't actually played with it.

So here I go.

For those wondering, there isn't technically any difference between the enterprise version and the normal puppet version but there are plenty of add ons that require the enterprise version (so I believe). The enterprise version will allow control of up to 10 nodes for free which is more than enough for a proof of concept.

I'm also hoping to build Puppet into a larger story about automation and orchestration.

Just to clarify, if you don't know the difference between automation and orchestration or think they mean the same thing here's the useful definition:
Automation is like musicians in an orchestra, looking the music and following the instructions, the orchestrator is the person up the front conducting, making sure everyone is on the same page and working together as a team.

In other words, the musicians are like the scripts or tools we use in lots of place to do useful work, like puppet agents or like simple shell scripts whilst the orchestrator would be something that can connect lots of systems and coordinate their efforts into something more useful than individual automations.

Hopefully that makes sense. There's a definite distinction between these two terms and it's useful to have an understanding of both for forming a bigger picture.

I'll post again when I've had time to play with my new puppet installation and have managed to make it do useful work.

Cheers.
