We can store values as plain text or encrypted data. However, the documentation does not say that pseudo parameters can be used in conjunction with other variables ie. when you have such a setup, you can easily do some checks before the execution. Did you enjoy reading this article?Would you like to learn more about software craft in data engineering and MLOps? If you define many state machines in serverless.yml you may reach the CloudFormation limit of 60 outputs. The generated CloudWatch alarms would have the following configurations: You can also override the default treatMissingData setting for a particular alarm by specifying an override: By default, the CloudFormation assigns names to the alarms based on the CloudFormation stack and the resource logical Id, and in some cases and these names could be confusing. Alternatively, you can also provide the raw ARN, or SQS queue URL, or DynamoDB table name as a string. Your application needs configuration data. $ sls invoke stepf --name --data '{"foo":"bar"}'.
