require two different types

[Tim Dunphy]

Hello,

 How can I require two different types in my manifests? For instance I have this setup in one of my modules:

file { "/etc/pki/tls/private/${::hostname}.example.com.key":

      owner => "bacula",

      group => "bacula",

      mode => 0400,

      require => Package["bacula-client","bacula-common"],

      require => File["/etc/pki/tls/private","/etc/pki/tls/certs"],

      source => "puppet:///modules/bacula/${::hostname}/${::hostname}.example.com.key",

      notify  => Service["bacula-fd"]

     }

And I want to require both Packages and directories provided by File. But when I try that I get this:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Duplicate parameter 'require' for on File[/etc/pki/tls/private/ldap1.example.com.key] at /etc/puppet/environments/production/modules/bacula/manifests/config.pp:43 on node ldap1.example.com

Warning: Not using cache on failed catalog

Error: Could not retrieve catalog; skipping run

How do I require both Files and Packages in such a way as to be acceptable to puppet?

Thanks,

Tim

Hi Tim,

The key is to use an array.

Such as

file { "/etc/pki/tls/private/${::hostname}.example.com.key":

source =>
"puppet:///modules/bacula/${::hostname}/${::hostname}.example.com.key",

owner => 'bacula',
group => 'bacula',

mode => '0400',

require => [
Package['bacula-client','bacula-common'],

File['/etc/pki/tls/private'],
File['/etc/pki/tls/certs'],
],
notify => Service['bacula-fd'],
}

Since the filesystem is hierarchical in nature, file resources are
implicitly ordered. So if you have a file resource for
'/etc/pki/tls/private' it is automatically done before this file
resource and should not be explicitly required.

Note that this is not same functionality as `mkdir -p`. So if
'/etc/pki/tls' did not exist, the resource for '/etc/pki/tls/private'
would fail and so would this file resource for the key.

You would correctly write your resource as follows.

file { "/etc/pki/tls/private/${::hostname}.example.com.key":

source =>
"puppet:///modules/bacula/${::hostname}/${::hostname}.example.com.key",

owner => 'bacula',
group => 'bacula',

mode => '0400',

require => [
Package['bacula-client','bacula-common'],

File['/etc/pki/tls/certs'],
],
notify => Service['bacula-fd'],
}

Even when requiring multiple resources of the same type, the above
format is the way to go.

Here's a link to make viewing the code a bit nicer.

Hi Garrett,

 That's great. And that explanation makes perfect sense! I understand this a little better now. And using the example you provided works.

Thanks,

Tim
