CloudFormation doesn't deploy to API gateway stages on update

Question

When I run CloudFormation deploy using a template with API Gateway resources, the first time I run it, it creates and deploys to stages. The subsequent times I run it, it updates the resources but doesn't deploy to stages. How can i solve this issue.

Answer

The reason that a deployment doesn't happen is because the Deployment in the template hasn't changed. CloudFormation changes resources based on modifications to the template and because the AWS::ApiGateway::Deployment isn't updated it doesn't trigger a new deployment is triggered in APi Gateway.

You can create a new deployment or you might try updating the Description or StageDescription - I haven't tried those last two but changing them might work.
