if statement not being parsed when trying to select omit the ensure parameter from a resource.

[Thom Luxford]

The intention is for the the service running state after boot to be optionally handled by puppet. Omitting the ensure parameter does this, but why can't I add it when I need it like this?

  

service { "$my_module::params::myServiceName":

    if $::my_service_ensure_running != 'undef' {

      ensure  => "$my_module::my_service_ensure_running",

    }

    enable  => 'true',

    require => [ Package["$oscar_legacy::params::mysqlPackageName"], File["/etc/mysql/conf.d/mysqld_oscar_dbs.cnf"] ],

  }

puppet parser validate {}

complains as so:

Error: Could not parse for environment production: Syntax error at '::my_service_ensure_running'; expected '}' at /home/oscara/git/puppetmaster/modules/my_module/manifests/init.pp:154

[David Schmitt]

the "if" is a statement that cannot be used inside a resource definition.

Write it like this:

service { "$my_module::params::myServiceName":
enable => 'true',
require => [ ...]

}

if $::my_service_ensure_running != 'undef' {

Service["$my_module::params::myServiceName"]{
ensure => $::my_service_ensure_running,
}
}

See the Puppet Language Reference
(http://docs.puppetlabs.com/puppet/latest/reference/lang_conditional.html)
for details.
