The nfs::exports class defines an exec, which runs exportfs -a, to export all filesystems defined in /etc/exports. Next, we define a concat resource to contain concat::fragments, which we will define next in our nfs::export class. concat resources specify the file that the fragments are to be placed into; /etc/exports in this case. Our concat resource has a notify for the previous exec. This has the effect that whenever /etc/ exports is updated, we run exportfs -a again to export the new entries:
class nfs::exports { exec {'nfs::exportfs': command => 'exportfs -a', refreshonly => true, path => '/usr/bin:/bin:/sbin:/usr/sbin', } concat {'/etc/exports': notify => Exec['nfs::exportfs'], } }
We then created an nfs::export ...
