Hi Raghu,
It sounds like you want to use the map function:
https://puppet.com/docs/puppet/6.17/function.html#map
Here's an example of how to use it with your data structure:
$array_inputs = $vm_data.map |$region| {
$hash_region = {
location => $region['location'],
vm_list => $region['vmlist'],
}
}
I have pulled out the following lines though, as the variable name
interpolation within a variable name is probably not going to work how
you're expecting it to:
customer_id => "customer-${$region['location']}",
api_key => "api-${$region['location']}",
secret_key => "secret-${$region['location']}",
For those lookups you are probably best off creating a separate lookup hash
perhaps like this:
$region_data = {
'apac' => {
'customer_id' => 'xxx',
'api_key' => 'yyy',
'secret_key' => 'zzz',
}
}
customer_id => "customer-${region_data['apac']['customer_id']}"
Cheers
Jesse
