    Given a 
    $vhosts
    hash we use to create Apache VirtualHosts, I’m trying to extract all the 
    servername
    values to make a list of SANs for a host-wide SSL key. Testing with printing out the 
    servername
    values:
    Copy code
    $vhosts.map |String $key, Hash $vhost| {
  notify { "$key":
    message => $vhost['servername']
  }
}
    prints one message per vhost entry with the defined 
    servername
    value, no problem:
    Copy code
    Notice: <http://phpappst1.tntech.edu|phpappst1.tntech.edu>
Notice: /Stage[main]/Profile::Apache/Notify[phpapps]/message: defined 'message' as '<http://phpappst1.tntech.edu|phpappst1.tntech.edu>'
Notice: <http://phpappst1.tntech.edu|phpappst1.tntech.edu>
Notice: /Stage[main]/Profile::Apache/Notify[phpapps-ssl]/message: defined 'message' as '<http://phpappst1.tntech.edu|phpappst1.tntech.edu>'
Notice: <http://ttupaapp-test.tntech.edu|ttupaapp-test.tntech.edu>
Notice: /Stage[main]/Profile::Apache/Notify[ttupaapp]/message: defined 'message' as '<http://ttupaapp-test.tntech.edu|ttupaapp-test.tntech.edu>'
...
    But trying to convert that into an array of names:
    Copy code
    $servernames = $vhosts.map |String $key, Hash $vhost| {
    $vhost['servername']
}
notify { "servernames":
  message => $servernames
}
    appears to only return the first value:
    Copy code
    Notice: <http://phpappst1.tntech.edu|phpappst1.tntech.edu>
Notice: /Stage[main]/Profile::Apache/Notify[servernames]/message: defined 'message' as '<http://phpappst1.tntech.edu|phpappst1.tntech.edu>'
    Where can I narrow this down? Puppet 6.27 if that makes any difference.

    The Notify resource type only outputs the first value of a given array. You need to build the string yourself. You can use the 
    join()
    function to join the names with commas for example.

    Copy code
    puppet apply -e 'notify {blah: message => [a, b, c].join(", ")}'
Notice: Compiled catalog for localhost in environment production in 0.03 seconds
Notice: a, b, c
Notice: /Stage[main]/Main/Notify[blah]/message: defined 'message' as 'a, b, c'
Notice: Applied catalog in 0.01 seconds
  • b
    that's why I often embed the array into a string:
    Copy code
    $ary = ['1', 2, 'bla']
notify { 'foo':
  message => "${ary}",
}
    Copy code
    Notice: [1, 2, bla]
Notice: /Stage[main]/Main/Notify[foo]/message: defined 'message' as '[1, 2, bla]'
Notice: Applied catalog in 0.01 seconds

    Thanks. Makes sense in retrospect.

    lookup('<lookup value>', Hash)
    is a lookup that returns the first value found, instead of all possible values, and fails if that value is not a 
    Hash
    type.

    lookup('<lookup value>', Hash)
    is a lookup that returns the first value found, instead of merging all possible values, and fails if that value is not a 
    Hash

    i have a question related to the 
    host
    resource. every time the agent runs, it updates the timestamp inside the 
    /etc/hosts
    file: 
    HEADER: This file was autogenerated at *2022-06-03 11:06:26 -0400*
    Is there a way to stop the timestamp being updated inside the 
    /etc/hosts
    file every time the agent runs or use something other that the 
    host
    resource?

    i wish services had a

    parameter in addition to the restart one, would potential make it way cleaner
  • t
    This works
    Copy code
    minute  => [13,28,43,58]
  • j
    ah, i think you put an array in an array
  • j
    hmm no, nm.
  • j
    i would double check the value of $minutes via a notify

    The README for zypprepo isn’t great, so you may want to refer to https://github.com/voxpupuli/puppet-zypprepo/blob/master/lib/puppet/type/zypprepo.rb for what the parameters control.

    I'm doing an if statement against a version string, I want to do if equal or greater the version string has points in it - will the greater than respect the points eg: understand that 1.9.11 is less than 1.9.12, or 1.10.1 and how do I correctly 'quote' the string, as I don't want it to be literal,
  • m
    eg: currently looks like if $::sw_version >= 1.9.11 {
  • m
    I know that's wrong though
  • g
    Check 
    versioncmp
    function - https://puppet.com/docs/puppet/6/function.html#versioncmp, so for your example:
    Copy code
    if versioncmp($::sw_version, '1.9.11') >= 0) {
   [...do stuff here...]
}
    would do stuff if version was 1.9.11 or greater
  • m
    ooooh
  • m
    that's a different way. thank you
  • m
    having a look at that function now
    👍 1
  • g
    the function is useful for comparing versions in the format you've mentioned - otherwise you'd have to split the version string into components to check 1.9.12 < 1.10.1 etc (if you just did >= on the strings directly from memory that's a string comparison, which most of the time isn't what you want)
  • m
    that's much better way, evaluating the return value based on the versioncmp test
