Puppet - 如果源不可用则静默退出

Question

Is it possible to silently exit if the source file is not available.

For example:

file {"/tmp/skin-${version}_${theme}.zip":
        source => "${file_location}/skin-${version}_${theme}.zip",
        ensure  => file,
        mode    => '0700'
    }
->
exec {"commands":  
         Here I will be processing the above downloaded file, if the url is not valid this block should not execute.
    }

In the above example if the file -> source url is not available, this should silently exit without any error.

Answer 1

With an onlyif on your exec it will only trigger if the test succeeds.

  exec { 'command':
    onlyif => "test -f /tmp/skin-${version}_${theme}.zip"
  }
