Ambiente do Chef 11.10.4 em execução no AWS Opsworks.
Não consigo descobrir como passar o valor da variável de bloqueio "cada um", "lyr", abaixo, com o atributo do nó node['aws-tag'][#{lyr}] ?
O bloco de código abaixo funciona das linhas 02-06, mas NÃO das linhas 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
Aqui estão os resultados do chef-shell mostrando os valores dos atributos mencionados no código acima:
chef > node ['opsworks'] ['instance'] ['camadas'] = > ["mongodb"]
chef > node ['aws-tag'] = > {"tags" = > {"aplicativo" = > "app1", "ambiente" = > "dev"}, "mongodb" = > {"serviço" = > "mongodb"}}
OBSERVAÇÃO: estou modificando o livro de receitas chef-aws-tag para marcar todas as instâncias do ec2 com as tags em node['aws-tag']['tags'] e, além disso, marca cada tag ec2 de instância opsworks que são incluídas no json personalizado passado para opsworks por camada, nesse caso, o conteúdo de node['aws-tag']['mongodb'] ou node['aws-tag']['LAYER'] , genericamente.
Se eu executar o código acima recebo um erro de compilação de receita: "keyword_do_block inesperado, esperando ']'" - veja abaixo a mensagem de erro detalhada do opsworks:

A linha 8 parece suspeita para mim, deve causar erros, conforme indicado ...
unless node['aws-tag'][#{lyr}].empty? || node['aws-tag'][#{lyr}].nil?
Deve ser uma interpolação de string, mas não é.
Experimente esta linha:
unless node['aws-tag']["#{lyr}"].empty? || node['aws-tag']["#{lyr}"].nil?
Se lyr já for uma string, basta usar lyr da seguinte forma:
unless node['aws-tag'][lyr].empty? || node['aws-tag'][lyr].nil?
