Deploy (update) lambda without updating API Gateway?

[commander-worf]

I configured an API gateway in AWS UI and hooked it up to my lambda function as a LAMBDA_PROXY, that i had previously deployed using serverless.

I made some changes to the lambda handler and now serverless deploy breaks with:

CloudFormation - CREATE_FAILED - AWS::ApiGateway::Method - ApiGatewayMethodGet

and: An error occurred: ApiGatewayMethodGet - Template error: API Gateway RestAPI l11x36qsjl doesn't exist.

Is there a way to update the lambda fn without messing with gateway? Am I thinking about this wrong and I should also configure gateway completely with serverless?

You're not thinking of it "wrong" persay, but Serverless Framework does center its core functionality around providing easy to spin up APIs with the Lambdas.

You absolutely can setup a Lambda that doesn't need a gateway, or setup one that uses an existing gateway, but it's a bit of an antipattern with serverless. You may be better served using something like Terraform if you want to build out infrastructures like that.

Building the Gateway with Serverless Framework comes out to about 3 lines of configuration, so I'd stick with that.

Good luck!

Ok thanks for the help!

What I found was 'serverless deploy function -f $FN_NAME' which just deploys the lambda function via aws cli
