January DevOps Meetup

Stephen Wallace - It's all about data separation... a Hiera crash course!

As the Puppet modules you write become more complex, you inevitably end up encoding a lot of business logic into your manifests and templates. Hiera was created to help you extract data and business logic from your modules to make them more re-usable, and easier to test. 

In this talk, Stephen will take you on a whirlwind tour of Hiera + Puppet and show you:

- What problems Hiera addresses
- The hiera.yaml structure, and how to traverse dynamic directories to find YAML based on facts
- How to write manifests that pull data from bindings and create "stuff" using create_resource
- The pros and cons of securing your sensitive data with hiera-gpg and hiera-eyaml


Lightning talks (5-10 minutes)

- Lindsay Holmwood - Things I wished I was told when I became a manager

David Favelle - ITIL and Devops - Bridging the Old and the New Worlds of IT

- Darragh Bailey - Tracking Upstream with Gerrit

If you want to give a lightning talk, please let Mick & Lindsay know!

      Just found out that the tool, mentioned in my talk, which I worked on for assisting tracking upstream projects has been opensourced! It's currently hosted at https://github.com/emo...­ thanks to Monty Taylor (for getting it ready) and Davide Guerri (for building on the basics to turn it into a proper tool)

      Can you do a talk on how to organise events? You seem to be doing a pretty good job at it.

    I forgot to mention last night that co-operation across the Ops towers is a challenge we've been working on in the ITIL/Ops space. We've used the concept of the Virtual Service Team with players from each tower - another example of a cross functional team. Agile does also does this. DevOps too. Lean would call this organising around the Value Stream. I feel a blog coming on...

      Curious to know if you've experience around using hiera to manage separate systems within the same test environment and what sort of structural layouts have worked best. I.e. we have a branch that we want to deploy the same revision multiple times to different groups of machines to test different configurations. Essentially it'll be the same environment for all. I suspect the best approach to avoid duplication of data may involve adding a 'systemgroup' fact and hiera config between the environment and nodes, but I'd be interested in hearing if there are other approaches.
