I’m trying to use this in start-api mode with docker-compose. I have this in my docker-compose.yml file:

version: '3'

services:
  amazon:
    image: cnadiminti/aws-sam-local
    command: local start-api --host 0.0.0.0 --docker-volume-basedir /var/opt
    ports:
      - '3000:3000'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./amazon:/var/opt

With the code from https://github.com/awslabs/aws-sam-local/tree/develop/samples/api-event-source in ./amazon. The container starts up, and seems to load template.yml just fine:

amazon_1   | nodejs6.10: Pulling from lambci/lambda

But hitting http://localhost:3000/ throws an error:

The files in that folder work fine via sam local start-api, so it’s not a file path issue.

I got this to work. --docker-volume-basedir needs to reference a path on the host, e.g. /Users/Geoffrey/Sites/project/amazon on my Mac, not /var/opt inside the container as I expected it to be. Submitted #2 to document this as an example for others.
