This is our hiera hierarchy:
environments/%{::environment}/hieradata/%{::certname}
environments/%{::environment}/hieradata/%{::role}
environments/%{::environment}/hieradata/%{::osfamily}
environments/%{::environment}/hieradata/common
hieradata/common
- Enhance the apache module with hiera
- In the root of your environment, "mkdir hieradata"
- cd hieradata
- touch $(hostname).desy.de.yaml
- touch web.yaml data.yaml compute.yaml
- touch RedHat.yaml
- touch common.yaml
- convert params to hiera() calls
- use "common".yaml for now
- convert the direct heira() calls to automatic lookups. Remember that if a class is called "foo" and it has a parameter "$bar" then you need a hiera key foo::bar
- In your environment, using at least 2 of the fqdn / role or osfamily yaml files you've created, add different values and see how they get used / override values in other parts of the hierarchy
Bonus:
- Try using hiera_include to include a class
