exec resource applied on every run

[Tim Dunphy]

Hey all,

 I've created a very basic puppet module to install bacula and ensure that it's running. However one exec statement in my manifest gets applied every time.

Here's the manifest:

class bacula::install {

   if $hostname == "ops" {

      file { "/var/bacula":

      ensure => directory,

      }

      file {"/backup/tapes":

        ensure => directory,

      }

      package { ["bacula-client", "bacula-common", "bacula-storage", "bacula-libs", "bacula-libs-sql", "bacula-director", "bacula-console"] :

      ensure => present,

      require => [ File["/var/bacula"], File["/backup/tapes"]]

      }

     exec { "update_mysql_alternatives":

     command => "alternatives --set libbaccats.so /usr/lib64/libbaccats-mysql.so",

     path    => "/usr/local/bin/:/bin/:/usr/sbin"

     }

  } else {

      package { ["bacula-client", "bacula-common"] :

      ensure => present,

      require => [ File["/var/bacula"], File["/backup/tapes"]]

      }

  }

}

Seems pretty straight forward. But how can I get the exec command to run only once if it hasn't been run previously? 

Thanks!

Tim

Thanks

Hi Tim,

The exec type has some attributes that can control this, such as "onlyif", "unless", and "creates".

Please review the documentation here:
