Add API endpoint to invoke AWS Lambda function running docker

Serverless Framework
1

Im using Serverless Framework to deploy a Docker image running R to an AWS Lambda.

service: r-lambda

provider:
  name: aws
  region: eu-west-1
  timeout: 60
  environment:
    stage: ${sls:stage}
    R_AWS_REGION: ${aws:region}
  ecr:
    images:
      r-lambda:
        path: ./

functions:
  r-lambda-hello:
    image:
      name: r-lambda
      command:
        - functions.hello

This works fine and I can log into AWS and invoke the lambda function. But I also want to invoke by doing a curl to it, so I added an “events” property to the functions section:

functions:
  r-lambda-hello:
    image:
      name: r-lambda
      command:
        - functions.hello
    events:
      - http: GET r-lambda-hello

Howevr, when I deploy with serverkless, it does not output the API endpoint. And when I go to API Gateway in AWS, I dont see any APIs here. What am I doing wrong?
