I want to create a directory that will contain NFS mount points.
Therefore, it makes
sense to have it in place before any of the NFS-related Puppet stuff. I
can do it
in either of two ways.
1. In a manifest, with a regular file resource, which contains the line
before => Class['nfs'],
No problem there.
2. If I try to do this via a lookup of equivalent Hiera data, I see
something unusual - or maybe just something I don't understand
properly.
If my Hiera data looks like this:
'/primary':
ensure: 'directory'
mode: '0755'
owner: 'root'
group: 'root'
before: 'Class[nfs]'
- I get an error when I run the agent on the node: "Server Error:
Invalid relationship:
File[/primary] { before => Class[nfs] }, because Class[nfs] doesn't seem
to be in the catalog".
But if I change "nfs" to "Nfs" - i.e .capitalize the first letter of the
class *name*,
it works.
I get that resource references should always be capitalized
(require => File['/etc/sysctl.d/recommended.conf'] and so on), but what
is going on with
the necessity for capitalizing the resource _name_ - "Nfs" in my example
- when
trying to accomplish the job via lookup and Hiera?
Thanks for any enlightenment,
These two lines are very different:
before => Class['nfs']
before: 'Class[nfs]'
The first is a real data type - a reference to a Class with the title
(i.e. name of class) 'nfs'. The second is a String that is interpreted /
parsed by the processing for the "before" meta parameter. Apparently it
does not get it quite right. Please file a ticket in Puppet's JIRA for
the PUP project.
Before doing this though, if you are on an older version this may have
been fixed already as the problem sounds vaguely familiar, so please try
on at least a 5.x version of puppet.
