EDIT: So, this blog was linked by DevOps Weekly #379, and seems to have climbed the SEO ranking for Hiera and Vault, but I’ve learn a lot and have some general changes since then.
I did a webinar on the subject I’ll be writing an updated version of how to use Vault and Hiera soon, and link it here.
Although I don’t work at Puppet anymore, it’s still my favourite config management software, and I use it for the management of machines under my control, including my home storage server and several MacBooks.
