将参数添加到 AWS CloudFormation / CodePipeline 堆栈

Question

I created an application from the AWS Console, in Lambda:

That app uses sam, cloud formation, code pipeline, etc. It comes with a parameter defined in template.yml :

Parameters:
  AppId:
    Type: String

but now I added a few more:

Parameters:
  AppId:
    Type: String
  CognitoUserPoolName:
    Type: String
  CognitoUserPoolClientName:
    Type: String

Where in AWS should I define the values for those?

Answer 1

You set Parameter Overrides in the sam deploy command or in samconfig.toml , both of which apply the values at deploy-time.

The --parameter-overrides option is a string of key-value pairs corresponding to the parameters in your SAM template.

sam deploy --parameter-overrides 'AppId=MyReallySuperApp,CognitoUserPoolName=AppPool' ...etc

BTW, the option is called Parameter Overrides because you can set a default template value for each Parameter.

Parameters:
  AppId:
    Type: String
    Default: MySuperApp
