Replace multiple expression with a variable in a selector

[Francisco José Bejarano]

Greetings to all

I have a question about the use of selectors. I am using 3.4.2

I have this selector in my code

  $testing = $::hostname ? {
    /(host1|host2|host3)/  => 'filetest',
    default                => 'file',
  }

I would like to use a variable as a multiple expression in a selector like this

$VARIABLE ='/(host1|host2|host3)/'

  $testing = $::hostname ? {
    $VARIABLE  => 'filetest',
    default    => 'file',
  }

¿Is that possible?

I've tried different ways but does not work. With quotes, without quotes, etc.. It always select the default file (file) if I put variable, but if I do not put variable (first code) it works ok and FileTest is used if hostname is in expression.

I would like to use VARIABLE in hiera to use the name of hosts (not in hard code)

¿Is that possible?

Thanks in advance :-)

try $VARIABLE ='(host1|host2|host3)'

$testing = $::hostname ? {

    /$VARIABLE/  => 'filetest',
    default    => 'file',
  }

Not runs

I have tried with all combinatios of quotes, arrays, hiera, etc. Only runs with literal values in the expression even I have replaced the selector with if statement

if $::hostname [ $variable ] {

and neither runs only with literal values

if $::hostname [ "host1","host2","host3" ] {

If anyone knows how it is done...

With this runs

hiera yaml

HOSTS_TESTING:
        - 'host1'
        - 'host2'
        - 'host3'

and manifest

$HOSTS_TESTING = hiera_array('HOSTS_TESTING')

  if $::hostname in $HOSTS_TESTING {

    $testing = 'filetest'
  } else {
      $testing = 'file'
  }

General remark: You should use hiera() to retrieve that value.
hiera_array() is only useful in very specific situations, and only if
you have a non-trivial hierarchy.
