Creating file resources using augeas works fine so far. I'm creating the yum configuration in /etc/yum.repos.d from hiera via

Hiera:

    system::yumrepos:
      'repo-local':
        baseurl   : <a href="http://mrepo.example.com/mrepo/centos$releasever-$basearch/RPMS.local/">http://mrepo.example.com/mrepo/centos$releasever-$basearch/RPMS.local/</a>
        descr     : CentOS-$releasever
        ...

Module:

     $yumrepo_hash = hiera_hash('system::yumrepos', undef)
     create_resources(yumrepo, $yumrepo_hash, $defaults)

This leaves however old entries and other files in the directory /etc/yum.repos.d untouched. Some of them having either the wrong specification or the wrong syntax, those needs to be removed.
When configuring

    file ...

Thanks for the suggestion. I was wrapping my head a bit more around it and solved it the following way:

  1. I introduced an additional parameter that per default doesn't do anything.
  2. If specified, it will create file resources with the right filenames in /etc/yum.repos.d (basically empty) files which then will be edited by the augeas tool correctly. All other "non-specified" files will be purged by the file/directory resource then. In case anybody facing the similar problem, here's the code:

Hiera

    system::params::yumrepos_keep  :
      - repo1
      - repo2

    system::yumrepos:
      'repo1:
        baseurl   : <a href="http://mrepo.example ...

I'm trying to do something similar but I haven't figured out how to make it not remove all the files and add them right back again.

class yum::repos (
    $config = undef,
) {

    $defaults = {
        enabled  => '1',
        gpgcheck => '0',
        priority => '20',
        'require' => File['/etc/yum.repos.d'],
    }

    # Remove all unmanaged repos
    file {'/etc/yum.repos.d':
        recurse => true,
        purge   => true,
    }

    if $config == undef {
        $repo_config = hiera_hash('yum::repos', undef)
    }
    else {
        $repo_config = $config
    }

    create_resources(yumrepo, $repo_config, $defaults)
}

That's why I introduced the other parameter that defines a file resource separately for the repositories to keep. By just creating the resource for every `*.repo` file Puppet knows ...(more)

For purge=>true to work as you were expected you at least need define resource or some other related resources. From the documentation

When recursively duplicating an entire directory with the source attribute, purge => true will automatically purge any files that are not in the source directory. When managing files in a directory as individual resources, setting purge => true will purge any files that aren’t being specifically managed.

To solve your problem there is always the old dirty exec resource where you can write an custom script, which will make sure that your folder is clean as expected. Not ... (more)
