Hello,
I have a yaml file with a hash of network interfaces (ifaces hash), each
nic has an associated ipaddress and netmask.
Using hiera ifaces fqdn=host.mycompany.com I can get all interfaces back.
Is there a way using the hiera cli to get a specific value of a key within
the hash?
e.g. hiera ifaces fqdn=host.mycompany.com
{"eth0"=>{"ipaddress"=>"10.4.115.48",
"netmask"=>"255.255.255.0"},
"eth0:1"=>{"ipaddress"=>"10.4.115.58",
"netmask"=>"255.255.255.0"}}
Can I with a single hiera command get info of only the interface eth0?
Or get just the ipaddress of interface eth0?
Or was hiera not meant for this kind of use?
Best Regards,
Jo

If you have created a hash in your hiera data, I believe that hiera can only
return that hash.
If you want a piece of it, you can process the hash after you get it out of
hiera and into your manifest.
I do not have a handy example to offer here, but maybe another list member can
help with that.

Via its programmatic interface (i.e. in Puppet), you would simply take the hash object returned by hiera and access the desired element by its key. If you want to be able to do similar from the command line then you probably should write your own Ruby program that does the same.
