将云形成文件分解为较小的脚本

Question

我有大型的cloudformation json文件，我用它来创建新的VPC，子网，ec2实例。基本上是研究将文件分解成多个小文件以便于维护。

如何创建a( create_vpc.json 和 vpc_param.json 文件。b( 如何从 AWS CLI 获取 VPC 列表并将 VPC 名称/ID 传递给 create_subnet.json 并定义 subnet_param.json。c( 使用 AWS CLI 获取 VPC 的子网列表，并将其作为参数传递给 create_routetable.json 和 routetable_param.json

同样想为 ec2/elb/其他东西创建其他脚本。

aws cloudformation create-stack --stackname startmyinstance  --template-body file:///some/local/path/templates/startmyinstance.json --parameters file:///some/local/path/params/startmyinstance-parameters.json

我当前的文件是：

Answer 1

您可以使用嵌套堆栈 - (此链接解释了它们是什么或何时使用(。如果您想查看示例模板或代码段，请访问此 AWS 页面以查看示例模板。

Answer 2

您可以使用cfpack.js来实现此目的。它允许您使用多个较小的模板，这些模板将内置到一个较大的模板中并部署到您的 CloudFormation 堆栈中。
