Just deploy cloudformation changes with serverless framework for AWS

Question

I am making changes just to custom resources in my serverless.yml with an AWS provider. The package from the lambda code is not changing, it's already uploaded to S3 from a previous deploy.

How can I say "use the artifacts already in S3, just upload the changed cloudformation template and update the stack using that"?

Updating only the infrastructure with the Serverless Framework is not something achievable as of right now. You will need to perform a full deployment even if there were no code changes.

However, executing a regular sls deploy won't do the trick if no code has changed as the framework won't detect infrastructure changes only. If you want to force a redeployment (i.e you have hooked up a new trigger for your Lambda function in your serverless.yml file), you must force the deployment by using the --force flag

sls deploy --force
