Question

I’ve looked at the documentation for puppet variables and can’t seem to get my head around how to apply this to the following situation:

if vagrant (local machine)

phpfpm::nginx::vhost { 'vhost_name':
    server_name => 'dev.demo.com',
    root        => '/vagrant/public',
}

else if aws ec2 (remote machine)

phpfpm::nginx::vhost { 'vhost_name':
    server_name => 'demo.com',
    root        => '/home/ubuntu/demo.com/public',
}

Thanks

Try running facter on both your vagrant host and your EC2 instance, and look for differences. I suspect that ‘facter virtual’ may be different between the two hosts, or that the EC2 may return a bunch of ec2_ facts that won’t be present on the vagrant host.

Then you can use this fact as a top level variable as per below. I switched to a case statement as well, since that’s a little easier to maintain IMHO, plus you can use the default block for error checking.

case $::virtual {
  'whatever vagrant returns' : {
    <vagrant specific provisionin>
   }
  'whatever the EC2 instance returns' : {
     <EC2 specific provisioning>
   }
   default : {
      fail("Unexpected virtual value of $::virtual")
   }
}
