將數組中的元素作為鍵傳遞給hiera查找

Question

嘗試執行人偶模塊時出現錯誤：

Error 400 on SERVER: certificatefqdn is not a hash or array when accessing it with certificatefile

這是我的hiera文件的樣子：

testmodule::install::certificates:
  test1.domain.com:
    certificatefile: 'certificate1.crt'
    certificatepass: 'testpass1'
  test2.domain.com:
    certificatefile: 'certificate2.crt'
    certificatepass: 'testpass2'
  test3.domain.com:
    certificatefile: 'certificate3.crt'
    certificatepass: 'testpass3'

我模塊中的init.pp看起來像這樣：

class testmodule (
  $certificates = hiera('testmodule::install::certificates'), 
 )
{
    $domains = [
      test1.domain.com',
      test2.domain.com',
      test3.domain.com',
    [

  testmodule::install { $domains:
    certificates => $certificates,
  }
}

我模塊中的install.pp看起來像這樣：

define testmodule::install ($certificates)

    {
       $domain = $name
       $certificatefqdn = $certificates["$domain"]
       $certificatefile = $certificatefqdn['certificatefile']
       $certificatepass = $certificatefqdn['certificatepass']
       notify{"This is the certificate file: $certificatefile" :}
    }

我期望為域數組中的每個元素看到這樣的輸出：

Notice: This is the certificate file: certificate2.crt
Notice: /Stage[main]/Testmodule/Testmodule::Install[certificate2.crt]/Notify[This is the certificate file: certificate2.crt]/message: defined 'message' as 'This is the certificate file: certificate2.crt'

相反，我看到了這個：

Notice: This is the certificate file: test2.domain.com['certificatefile']
Notice: /Stage[main]/Testmodule/Testmodule::Install[test2.domain.com]/Notify[This is the certificate file: test2.domain.com['certificatefile']]/message: defined 'message' as 'This is the certificate file: test2.domain.com['certificatefile']'

如何使用域中的元素作為初始密鑰正確訪問hiera中嵌套哈希中的密鑰？

Answer 1

該代碼似乎已經正確。

我已經根據您的問題進行了設置：

1 /

# manifests/init.pp
class test (
  $certificates = hiera('test::install::certificates'), 
) {
  $domains = [
    'test1.domain.com',
    'test2.domain.com',
    'test3.domain.com',
  ]

  test::install { $domains:
    certificates =>  $certificates,
  }
}

2 /

# manifests/install.pp 
define test::install ($certificates) {
  $domain = $name
  $certificatefqdn = $certificates["$domain"]
  $certificatefile = $certificatefqdn['certificatefile']
  $certificatepass = $certificatefqdn['certificatepass']
  notify{"This is the certificate file: $certificatefile" :}
}

3 /

# spec/fixtures/hiera/data/common.yaml 
---
test::install::certificates:
  test1.domain.com:
    certificatefile: 'certificate1.crt'
    certificatepass: 'testpass1'
  test2.domain.com:
    certificatefile: 'certificate2.crt'
    certificatepass: 'testpass2'
  test3.domain.com:
    certificatefile: 'certificate3.crt'
    certificatepass: 'testpass3'

4 /

# spec/fixtures/hiera/hiera.yaml 
---
version: 5
defaults:
  datadir: data
  data_hash: yaml_data
hierarchy:
  - name: "All levels"
    paths:
    - common.yaml

編譯並應用：

$ bundle exec puppet apply --modulepath spec/fixtures/modules --hiera_config spec/fixtures/hiera/hiera.yaml -e 'include test'

所以我無法重現。
