How to automatize NET 6 Lambda deployment?

Hi

for Lambda you should look into AWS SAM: https://aws.amazon.com/serverless/sam/, which should fix the part about how to deploy Lambda functions.

Here is a guide about how to set it up with Github actions, as an example: https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/deploying-using-github.html

In regards about the part about the rest of the infrastructure (RDS/api gw, etc..) you should look into an Infrastructure as Code tool such as CDK, Terrraform or others.

Hope it helps and if it does I d appreciate the answer to be accepted so that community can benefit for clarity, thanks ;)
