how can I call ruby function basename in puppet

  • 772

I'd like to call function File.basename which is available in Ruby. Is it possible in puppet?

Something like:

$filename = basename($download_url)
puppet

    Ruby functions are not directly available in Puppet, but you can use inline_template:

    $filename = inline_template('<%= File.basename(download_url) %>')

  2. meanwhile it is possible to use the puppetlabs-stdlib which provides a basename() function.

    Returns the basename of a path (optionally stripping an extension). 

    basename('/path/to/a/file.ext') returns 'file.ext'
basename('relative/path/file.ext') returns 'file.ext'
basename('/path/to/a/file.ext', '.ext') returns 'file'

  3. No, you can not call arbitrary Ruby functions in a Puppet manifest, but you can do so in Puppet templates which use ERB. Have a look at the inline_template function, which might be useful for your use case.
