Среда Chef 11.10.4, работающая в AWS Opsworks.
Я не могу понять, как передать значение переменной блока "each do", "lyr", ниже, с атрибутом узла node['aws-tag'][#{lyr}]?
Приведенный ниже блок кода работает со строками 02-06, но НЕ со строками 07-14.
[01] include_recipe "aws"
[02] unless node['aws-tag']['tags'].empty? || node['aws-tag']['tags'].nil?
[03] aws_resource_tag node['ec2']['instance_id'] do
[04] tags(node['aws-tag']['tags'])
[05] action :update
[06] end
[07] node['opsworks']['instance']['layers'].each do |lyr|
[08] unless node['aws-tag'][#{lyr}].empty? || node['aws-tag'][#{lyr}].nil?
[09] aws_resource_tag node['ec2']['instance_id'] do
[10] tags(node['aws-tag'][#{lyr}])
[11] action :update
[12] end
[13] end
[14] end
[15] end
Вот результаты chef-shell, показывающие значения атрибутов, упомянутых в приведенном выше коде:
повар> узел ['opsworks'] ['экземпляр'] ['слои'] => ["mongodb"]
chef> node ['aws-tag'] => {"tags" => {"application" => "app1", "environment" => "dev"}, "mongodb" => {"service" => " mongodb "}}"
ПРИМЕЧАНИЕ: я изменяю chef-aws-tag поваренная книга, чтобы пометить все экземпляры ec2 тегами в node['aws-tag']['tags'] и в дополнение к тегам для каждого экземпляра ec2, специфичных для уровня opsworks тегов, которые включены в пользовательский json, передаваемый в opsworks по слоям, в данном случае содержимое node['aws-tag']['mongodb'] или node['aws-tag']['LAYER'], в общем.
Если я запускаю приведенный выше код, я получаю ошибку компиляции рецепта: «неожиданно keyword_do_block, ожидая ']'» - подробное сообщение об ошибке от opsworks см. Ниже:

Строка 8 кажется мне подозрительной, должна вызывать ошибки, как указано ...
unless node['aws-tag'][#{lyr}].empty? || node['aws-tag'][#{lyr}].nil?
Должна быть строковая интерполяция, но это не так.
Попробуйте эту строку:
unless node['aws-tag']["#{lyr}"].empty? || node['aws-tag']["#{lyr}"].nil?
Если lyr уже является строкой, тогда просто используйте lyr вот так:
unless node['aws-tag'][lyr].empty? || node['aws-tag'][lyr].nil?
