我有大型的cloudformation json文件，我用它來創建新的vpc，子網，ec2實例。 基本上打破文件分成多個小文件，以方便維護。將雲信息文件分解爲更小的腳本
如何創建 a）create_vpc.json和vpc_param.json文件。 b）如何從aws cli獲取vpc列表並將vpc名稱/ id傳遞給create_subnet.json並定義subnet_param.json。 c）使用aws cli獲取vpc的子網列表，並將其作爲參數傳遞給create_routetable.json和routetable_param.json。
同樣想要爲ec2/elb /其他東西創建其他腳本。
aws cloudformation create-stack --stackname startmyinstance --template-body file:///some/local/path/templates/startmyinstance.json --parameters file:///some/local/path/params/startmyinstance-parameters.json
我的當前文件是：
