Description

Just a very simple module to convert:

roles

• A role fact role into a safe_role
• A trusted fact role pp_role into safe_pp_role

The conversion process is to convert double colons (::) into slashes (/).

os

• A normalised safe_os fact:
  • All values lowercased (eg: RedHat -> redhat)
  • All spaces removed from values (eg 2012 R2 -> 2012_r2)

This lets us write hiera.yaml files that look like this:

:hierarchy:
  - "node/%{clientcert}".yaml
  - "%{safe_role}".yaml
  - "app_tier/%{app_tier}".yaml
  - "datacenter/%{datacenter}".yaml
  - "env/%{environment}".yaml
  - "os/%{facts.safe_os.family}_%{facts.safe_os.release.major}.yaml"
  - common.yaml

This means that:

• A node that has a role or pp_role value of foo::bar::baz will attempt to read hiera data from role/foo/bar/baz.yaml (instead of role/foo::bar::baz.yaml)
• A windows 2012 R2 node would attempt to read from os/windows_2012_r2.yaml (instead of os/windows_2012 R2.yaml)
• A RHEL 7 node would attempt to read read from os/redhat_7.yaml (instead of os/RedHat_7.yaml)

This resolves the problems that:

• :: in filenames only works on linux
• Windows and MacOS have case insensitive filesystems which can result in broken git repositories when files are checked in accidentally that differ only by case
• Filenames need spaces when dealing with some Windows variants

Setup

Just install the module and the facts will be created if applicable

Limitations

• Requires openssl in the PATH

Development
