Why can't I install a Yum repository from RPM and then enable it?

Given a manifest like this, where I install a Yum repository RPM and then enable it with a yumrepo resource, I'd expect it to end up with a usable package repository.

package { 'epel-release':
  provider => rpm,  
  source   => 'http://mirror.us.leaseweb.net/epel/6/i386/epel-release-6-8.noarch.rpm',
  ensure   => installed,
}
->
yumrepo { 'epel':
  enabled     => 1,
  includepkgs => 'python-virtualenv python-pip', # others can conflict with asterisk
}

Instead, the final result is a Yum repo file that looks like

# cat /etc/yum.repos.d/epel.repo
[epel]
enabled=1
includepkgs=python-virtualenv python-pip

Obviously, that's not what I want. How can I make it work ... (more)

This is a classic example of trying to manage a single resource with multiple definitions. Remember that Puppet isn't a scripting language, it's a state modeling language. Instead of thinking of it in steps of (1) install repository; (2) manipulate repository, you should instead just describe the state that you want that resource to be in.

To achieve that in a simple and easy way, you could install the RPM on a representative system, then use Puppet itself to generate the resource declaration you'd need to recreate it. Here is an example of that.

[root@monkey ~]# rpm ...

For the specific repo in the example, there is a very nice Forge module, stahnma/epel, which will take care of this for you.

Generally, you should be able to pass parameters to the Yumrepo type which will make the Package resource declaration unnecessary and thus avoid your current conundrum.

On my Dell physical servers I use wget to download and execute the rpm to enable their repo and install OMSA. Heres my code block. You should be able to do something very similar to enable the EPEL repo

if $manufacturer =~ /Dell/ {
exec { 'omsa_install' :
  path         => '/bin:/usr/bin:/usr/sbin:/sbin',
  command      => 'wget -q -O - $omsa_url | bash',
  creates      => '/etc/yum.repos.d/dell-omsa-repository.repo',
  before       => Package [ "srvadmin-all" ]
}
package { 'srvadmin-all' : }
