specifying tidy resources in hiera (solved)

[Derek Dresser]

Hello,

I was looking for a clean way to specify tidy resources in my hiera hierarchy.  Basically, I wanted to be able to specify common tidy resources, or tidy resources specific to a host without editing a module or class each time, essentially separating the data from the logic.  Here I'm using this for tidy, but the same model could be used for other resources.

I came up with a solution using "create_resources" that works so I thought I'd share.

assuming the two following yaml files.

#### common.yaml #######
---
tidyup:
  /tmp:
     age: '4w'
     backup: 'false'
     recurse: 'true'

#### myhost.yaml #####
---
classes : [ 'tidyup' ]

tidyup:
  /tmp/dir1:
     age: '1s'
     backup: 'false'
     recurse: 'true'
  /tmp/dir3:
     age: '1s'
     backup: 'false'
     recurse: 'true'

I created a module named 'tidyup' that contains one class.

class tidyup {
$tidydirs = hiera_hash('tidyup', [])
create_resources('tidy',$tidydirs)
}

This class gathers up the tidyup resources defined at all levels of the hierarchy and performs the specified tidy tasks.  You can see what is returned by running 'hiera' on the command line.

hiera -h tidyup hostname=myhost

result:

{"/tmp/dir3"=>{"age"=>"1s", "backup"=>"false", "recurse"=>"true"}, "/tmp/dir1"=>{"age"=>"1s", "backup"=>"false", "recurse"=>"true"}, "/tmp"=>{"age"=>"4w", "backup"=>"false", "recurse"=>"true"}}
