Iterate over an array of hashes in puppet
0
I have hiera data in puppet as follows:
elasticsearch::cluster_name: 'elasticsearch-dev'
elasticsearch::masterlist: [ "elasticsearchdev01.domain.com", "elasticsearchdev02.domain.com", "elasticsearchdev03.domain.com" ]
elasticsearch::kibanalist: [ "kibanadev01.domain.com" ]
And my manifest contains this:
$masterlist = hiera('elasticsearch::masterlist')
$kibanalist = hiera('elasticsearch::kibanalist')
if ( $::fqdn in $masterlist ) or ( $::fqdn in $kibanalist ) {
$cluster_name = hiera('elasticsearch::cluster_name')
}
else {
notify { 'No cluster for node':
message => "${::fqdn} is not configured to be in any cluster in the hiera data",
}
}
I would like to modify this to allow multiple clusters to be configured for a single environment, and I'm not sure of the best way to implement this. I want to be able to group the master lists with their corresponding cluster names, and then call the relevant cluster name for each node.
I think perhaps I need to use an array of hashes and iterate over it, but I don't know how to cover this in my manifest.

You would probably want to restructure your data as a Hash of Hashes:
elasticsearch::clusters:
'elasticsearch-dev':
masterlist: [ "elasticsearchdev01.domain.com", "elasticsearchdev02.domain.com", "elasticsearchdev03.domain.com" ]
kibanalist: [ "kibanadev01.domain.com" ]
And then have in your manifests:
$clusters = hiera('elasticsearch::clusters')
$mycluster = $clusters.filter |$cluster, $data| {
($::fqdn in $data['masterlist']) or ($::fqdn in $data['kibanalist'])
}
if ($mycluster.empty) {
notify { 'No cluster for node':
message => "${::fqdn} is not configured to be in any cluster in the hiera data",
}
}
$cluster_name = $mycluster.keys[0]
notice($cluster_name)
You might want to also consider replacing the deprecated hiera() call with lookup() and using $facts['networking']['fqdn'] instead of the legacy $::fqdn.

This gave me a great place to start. After implementing this I think that what I actually want to do is write a function that will search all the master/kibana lists in the hiera data (given multiple clusters configured) for the fqdn of the node. If it is not there it will send a notify, and if it is then it will return the corresponding cluster name, masterlist and kibanalist. I can see that I can search the lists from what you have suggested above, but I then don't seem to be able to use any variables set outside of the iteration.
