Our infrastructure uses puppet with public puppet modules. All our secrets and our installation-spesific parameters are thus placed in hiera.
Data distribution
The hieradata directory contains multiple .yaml files holding our information. When we have multiple puppet masters its important that each of the puppetmasters have an updated version of the hieradata, in addition to an updated list of puppet-modules. As the hiera-data are full of secrets we cannot publish them on github, and have all puppetmasters pull the information from there. What we do instead is to let the hieradata be a local git-repo which each puppetserver is pulling from eachother.
Hiera keys
Depending on what services you are handling with puppet, you might need various keys in hiera. This page tries to list which keys needs to be present to use our role/profile repositories.
Keys in italic are optional
General information
There are quite a bit of data which are not associated to a specific service, but are rather used by various modules, and should thus generally allways be present:
