Puppet Hiera Hash SubKey Interpolation

[Manoj Kumar]

Hi All,

Can you guys please help me to get the hiera hash subkey value in yaml files?

What I have in exec.yaml

talend::exec_mount_points:

    dataloading2:

        ad_user : 'user123'

        ad_password: 'test123'

        ad_domain: ''

        creds_file: 'passfile'

        mount_source: '//SOME-IP/data'

        mount_point: '/media'

        mount_options: "uid=edmadmin,gid=sftp-only,credentials=%{hiera('talend::creds_base_dir')}/.%{hiera('talend::exec_mount_points::dataloading2::creds_file')},defaults,sec=ntlm"

        mount_ensure: 'mounted'

        onboot: true

        fs_type: 'cifs'

I need to get the value from the above hash to use in its Subkey (creds_file) value like in mount_options: %{hiera('talend::exec_mount_points::dataloading2::creds_file')}

But I am getting nil/blank value. Can anyone suggest on this please

I am not sure if you can lookup a subkey like that in hiera. (i could be wrong)

But this is how i do something similar. 

I do a hiera lookup for the hash in the class

$mount_points=hiera('talend::exec_mount_points')

Then i pull out all the keys

$mount_points_keys = keys($mount_points)

Then using the keys you can lookup subkeys in the hash

$creds_file_1=$mount_points[$mount_points_keys][creds_file]

Thanks

In later versions of puppet/hiera, it is possible to use dot (.)
notation to lookup a value within the data that is produced by they key.
It is possible to use both strings and numbers (for arrays).

For example:

talend::exec_mount_points.dataloading2.creds_file

A dot is not allowed as being part of the key. Again, later versions
will allow escaping parts of a key that contains dot by enclosing that
part in quotes.
