Я использую Chef 11.10.4, работающий в AWS Opsworks.
Я не могу понять, как объединить элемент lyr
с атрибутом узла node['aws-tag'][#{lyr}]
в строках 07-14 ниже.
Я использую подстановку строк в качестве псевдокода, чтобы показать, что я пытаюсь сделать, но в данной ситуации это явно не работает. Строки 02-06 работают отлично, я просто пытаюсь заставить работать строки 07-14, и я не знаю, как это сделать.
include_recipe "aws"
unless node['aws-tag']['tags'].empty? || node['aws-tag']['tags'].nil?
aws_resource_tag node['ec2']['instance_id'] do
tags(node['aws-tag']['tags'])
action :update
end
node['opsworks']['instance']['layers'].each do |lyr|
unless node['aws-tag'][#{lyr}].empty? || node['aws-tag'][#{lyr}].nil?
aws_resource_tag node['ec2']['instance_id'] do
tags(node['aws-tag'][#{lyr}])
action :update
end
end
end
end
Вот результаты от chef-shell, показывающие значения атрибутов, упомянутых в приведенном выше коде:
chef > node['opsworks']['instance']['layers']
=> ["mongodb"]
chef > node['aws-tag']
=> {"tags"=>{"application"=>"app1", "environment"=>"dev"}, "mongodb"=>{"service"=>"mongodb"}}
Я изменяю кулинарную книгу chef-aws-tag, чтобы пометить все экземпляры ec2 с помощью теги в node['aws-tag']['tags']
и в дополнение к тегам каждого экземпляра ec2, специфичные теги уровня opsworks, которые включены в пользовательский JSON, передаваемый в opsworks по уровням, в данном случае содержимое node['aws-tag']['mongodb']
или node['aws-tag']['LAYER']
, как правило.
Если я запускаю приведенный выше код, я получаю сообщение об ошибке компиляции рецепта: «неожиданное ключевое слово_do_block, ожидающее ']'» — подробное сообщение об ошибке от opsworks см. ниже:
