    puppet lookup profile::stream_web::config
  • p
    Then I get
    Copy code
    Notice: {developmentb => {someattribute => here, anotherattribute => here}}
  • p
    Copy code
    Notice: {developmentc => {someattribute => here, anotherattribute => here}}

    https://github.com/betadots/hdm will make this debugging so much easier

    Looks like I can’t access value via $value[‘someattribute’] but I don’t understand why
  • p
    Sorry - this must be painful for you experienced puppet guys…

    I also recommend: • typing the lambda in the 
    each
    loop, so that Puppet validates that each element matches that data type.

    You don't have to use arrays in your data. I would use
    Copy code
    profile::stream_web::config:
  developmentb:
    someattribute: 'here'
    anotherattribute: 'here'
  developmentc:
    someattribute: 'here'
    anotherattribute: 'here'

config.each | $deployment, $attrs | {
  notify { "${deployment}: someattribute: ${attr['someattribute']}": }
}

    The Hash’s first-level key is 
    developmentb
    , not 
    someattribute
  • b
    you need to iterate on | $key, $value |
  • b
    you’re getting an array of single items instead of keys and values
  • p
    ah right!
  • b
    yes, what @vchepkov said
  • p
    I will try @vchepkov’s suggestion

    What @natemccurdy said is what your problem is.
  • h
    if you do what @binford2k suggests on the array you will get 0, then 1, then 2 etc in $key.
  • b
    (and then fix the yaml so it’s the intended hash 😁)
  • p
    Hmmm - So have changed my hiera to:
  • p
    Copy code
    profile::stream_web::config:
  muc:
    'developmentb':
       someattribute: 'here'
       anotherattribute: 'here'
    'developmentc':
       someattribute: 'here'
       anotherattribute: 'here'
  • p
    And my full manifest is currently:
  • p
    Copy code
    class profile::stream_web (
  $config = [],
) {

  $muc = $config['muc']
  $muc.each | $value | {
    $d1 = $value['someattribute']
    notify { "$d1": }
  }
  • v
    do you need 'muc' ? is there anything else on that level ?
  • p
    Possibly making progress, but that results in: Evaluation Error: The value ‘someattribute’ cannot be converted to Numeric.

    start with one piece. The Hiera data is probably the easiest. What are you trying to achieve?
  • b
    the ability do do something like “get config data for deployment ‘developmentb’“?
    ✅ 1
  • b
    paste that yaml into something like https://codebeautify.org/yaml-parser-online and parse it
  • b
    see what data structure shows up on the right
