From Serverless 1.X, I can't found API Gateway settings in serverless.yml or web search results. It include only lambda settings, and I deployed Hello World template to my AWS, actually only lambda was deployed.
How to deploy and configure API Gateway on Serverless 1.X?
I found the answer of this by myself.
It is written in document here,
https://serverless.com/framework/docs/providers/aws/events/apigateway/
and also, I was so careless, there are some sample of setting commented out in template.
This API Gateway setting is written like this:
functions:
hello:
handler: handler.hello
events:
- http:
path: hello
method: get
So, API Gateway deploy setting is part of "functions=>events" setting.
