# SSM Parameter Store helper for CloudFormation templates

You know what's lame? CloudFormation not (yet) having support for storing values 

in [Parameter Store][aws-pstore]. You know what's less lame? [Lambda-backed custom resources][cfn-res]

so that we can polyfill this ourselves. Simply deploy [`cfn.yml`](cfn.yml) into

your AWS region and use like this:

```yaml

AWSTemplateFormatVersion: "2010-09-09"

Parameters:

  SecretValue:

    Description: Sssh, it's a secret

    Type: String

    NoEcho: true

Resources:

  SecureParam:

    Type: Custom::CfnParamStore

    Properties:

      ServiceToken: !ImportValue CfnParamStore

      Type: SecureString

      Value: !Ref SecretValue

Outputs:

  ParamArn:

    Description: Arn of param in SSM param store

    Value: !GetAtt SecureParam.Arn

```

Note that neither CloudFormation, Lambda nor Parameter Store are global resources,

so you will have to deploy the helper stack into each region

that you wish to use this in.
