You can use custom actions like this: Request template is not used when action is set because there're a bunch of actions. Configuring in such way adds "DeletionPolicy" : "Retain" to the state machine within CloudFormation template. # serverless.yml# Stage parametersparams:# Values for the "prod" stageprod:my-parameter:foo# Values for the "dev" stagedev:my-parameter:bar Provider General settings How to inject serverless parameter from environment variables?

To implement a blue-green deployment with Step Functions you need to reference the exact versions of the functions. !Sub, !Ref) is not supported at the moment. Use --data and pass is any format of data you want to send it to the local lambda. Please check the page of Event Types for CloudWatch Events. The default values are always mentioned in the provider. Alternatively, you can also provide the raw ARN, or SQS queue URL, or DynamoDB table name as a string. Thanks so much @str3tch for the quick turnaround and the pointers. What does and doesn't count as "mitigating" a time oracle's curse? In my serverless.yaml, I specify environment variables to be loaded from a file based on the stage parameter ( dev is default): provider: stage: $ {opt:stage, 'dev'} environment: FOO: $ {file (./config.$ {self:provider.stage}.js):getEnvVars.FOO} BAR: $ {file (./config.$ {self:provider.stage}.js):getEnvVars.BAR} Refresh the page, check Medium 's site status, or find something.
