我们可以在System Manager 的 Parameter Store里面定义一些参数，然后在我们的cloudformation 模板文件里面直接调用这些参数。下面给两个例子进行说明。
例1. 通过 Parameter Store来传入参数。
来看看下面的模板文件，这是一个标准的模板文件，他会创建一个EC2实例和一个安全组。参数部分，我们定义了KeyName， InstanceType 和SSHLocation。作为对照，我们尝试把InstanceType这部分通过Parameter Store的参数替换。

}首先在AWS System Manager里面的Parameter Store里面创建两个参数
这两个参数都是string类型，devinstance 我定义为 t2.micro; prodinstance我定义为 t3.micro
然后我们可以在模板文件的parameters 部分，通过 "AWS::SSM::Parameter::Value<String>" 这种方式来直接调用参数，这里我设置了一个默认值
执行看看
1分钟左右就创建好了
可以看见EC2的类型和我定义的参数是一致的
例2 在Resource部分调用Parameter Store的参数
同样的，我们做一个对照性的修改。这个是原始的模板，创建一个publicread 的S3 Bucket。ACL权限是写死的，我们把他改成parameter store的参数
AWSTemplateFormatVersion: 2010-09-09
Description: >-
AWS CloudFormation Sample Template S3_Website_Bucket_With_Retain_On_Delete:
Sample template showing how to create a publicly accessible S3 bucket
configured for website access with a deletion policy of retail on delete.
**WARNING** This template creates an S3 bucket that will NOT be deleted when
the stack is deleted. You will be billed for the AWS resources used if you
create a stack from this template.
Resources:
S3Bucket:
Type: ‘AWS::S3::Bucket‘
Properties:
AccessControl: PublicRead
WebsiteConfiguration:
IndexDocument: index.html
ErrorDocument: error.html
DeletionPolicy: Retain
Outputs:
WebsiteURL:
Value: !GetAtt
- S3Bucket
- WebsiteURL
Description: URL for website hosted on S3
S3BucketSecureURL:
Value: !Join
- ‘‘
- - ‘https://‘
- !GetAtt
- S3Bucket
- DomainName
Description: Name of S3 bucket to hold website content先定义一个参数
新的参数S3Access
然后在我们的模板文件里面，这次我们需要在Resource部分调用，这里需要使用另外一个方式调用 resolve:ssm:S3Access:1
执行看看
我们的S3 bucket的 Access 是PublicRead的，这和我们在Parameter Store里面配置的是一致的
