puppet overriding file resource on a module

Question

i am using this CIS module arildjensen/cis-puppet

and want to override the /etc/profile file declaration on the CIS module

so i created this new manifest, following this post

class profile::hadoop::settings inherits cis {

      file { '/etc/profile':
        ensure => 'file',
        owner  => 'root',
        group  => 'root',
        mode   => '0600',
        source => 'puppet:///modules/profile/hadoop/etc/profile',
      }
  }

however this still gives the error

Error: Duplicate declaration: File[/etc/profile] is already declared in file /tmp/vagrant-puppet/modules-ab9b45e51a68912cdc576c81d46a2260/profile/manifests/hadoop/settings.pp:9; cannot redeclare at /tmp/vagrant-puppet/modules-ab9b45e51a68912cdc576c81d46a2260/cis/manifests/linuxcontrols/c0076.pp:12 on node server.localdomain

The syntax for a resource override is different from the syntax for a resource declaration. You're looking for this:

class profile::hadoop::settings inherits cis {

    File['/etc/profile'] {
        ensure => 'file',
        owner  => 'root',
        group  => 'root',
        mode   => '0600',
        source => 'puppet:///modules/profile/hadoop/etc/profile',
    }
}

Syntactically, it's a resource reference (which makes sense) with an appended list of property overrides.

That's the old-school way, of course. Since at least Puppet 3.0, you can also perform overrides with a collector, in which case you don't need class inheritance:

class profile::hadoop::settings {
    include 'cis'

    File<|title == '/etc/profile'|> {
        ensure => 'file',
        owner  => 'root',
        group  => 'root',
        mode   => '0600',
        source => 'puppet:///modules/profile/hadoop/etc/profile',
    }
}
