Add parameter to an AWS CloudFormation / CodePipeline stack-CodePudding

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

That app uses sam, cloud formation, code pipeline (deploying automatically on each push to Github), 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?

Note: I don't deploy by running sam deploy, Code Pipeline deploys automatically for me. That's how that "Serverless API backend" template works out of the box.

CodePudding user response：

SAM

You set Parameter Overrides in the sam deploy command or in samconfig.toml locally.

# 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

CodePipeline

CodePipeline,pipeline deploy stages also accept parameter overrides, in the console or with the update-pipeline api command. You can create additional deploy stages for each combination of a stack's parameter values you wish to deploy.

However you provide them, parameter values are set at deploy-time. You can view a deployed stack's parameter values in the CloudFormation console.

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

Parameters:
  AppId:
    Type: String
    Default: MySuperApp
