serverless stage parameters

I'm guessing that because the parameter is empty (null), it is recognized as non . When we use Serverless, the only distinction between production deployment and the testing environment is the configuration we use during the deployment. Typically, you will have a staging environment that replicates the same configuration as the production environment. Clients connecting to this Rest API will then need to set any of these API keys values in the x-api-key header of their request. Its pretty quick! Your function's stage is set to 'dev' by default. You dont have the same level of flexibility to fine tune the IAM policies for stages of the same API, when compared to tuning different APIs. In this article, we are going to see how to store all these variables in AWS Parameter Store, which is a service under the AWS Systems Manager. rev2023.1.18.43172. It was developed to help users build and deploy web, mobile, and IoT applications on a variety of cloud services. This allows for an IAM role to be created, and applied to the state machines all within the serverless file.

"A Hello World example of the Amazon States Language using an AWS Lambda Function", arn:aws:sns:us-east-1:1234567890:NotifyMe, # imports a table name from an external stack, # enable pre-deployment definition validation (disabled by default), sendMessageFunc-${self:custom.service}-${opt:stage}, $[stateMachineName]-$[cloudWatchMetricName]-alarm, mycustom-name-${self:stage.region}-Failed-alarm, # for FIFO queues, which requires you to configure the message group ID, # used to choose the parition key from payload, myStateMachine-${self:service}-${opt:stage}, MyStateMachineDash${self:service}Dash${opt:stage}, # REST API resource ID. What you can do in serverless.yml is: What this says is to use the stage CLI option if it exists, if not, use the default stage (which lives in provider.stage). It is also possible to use the CloudFormation intrinsic functions to reference resources from elsewhere. Variables in AWS Secrets Manager can be referenced using SSM, just use the ssm:/aws/reference/secretsmanager/secret_ID_in_Secrets_Manager syntax. You can use CloudFormation intrinsic functions such as Ref and Fn::GetAtt to reference Lambda functions, SNS topics, SQS queues and DynamoDB tables declared in the same serverless.yml.
