how to connect to local dynamo DB in docker compose?

[davidxiao]

Hi, it can connect to separate dynamoDB, while when all the service and DynamoDB in one docker compose, then local seems not work, maybe need to update some logic update fixed localhost when region is local?

[davidxiao]

can not connect to dynamoDB from docker-compose:

{
  credentials: {
    accessKeyId: "DynamoDBLocal",
    secretAccessKey: "DoesNotDoAnyAuth",
    sessionToken: "preferTemporaryCredentials"
  },
  region: "local",
  host: "dynamodb",
  port: 8001,
  cache: {
    _credentialScope: "",
    _signingKey: null,
    _accessKeyId: "",
    _sessionToken: "",
    refresh: [AsyncFunction: refresh],
    signingKey: null,
    credentialScope: "",
    accessKeyId: "",
    sessionToken: ""
  },
  method: "POST",
  endpoint: "http://dynamodb:8001/"
}

got error:

error: Uncaught Http: error sending request for url (http://dynamodb:8001/): error trying to connect: tcp connect error: Connection refused (os error 111)
    at unwrapResponse ($deno$/ops/dispatch_json.ts:43:11)
    at Object.sendAsync ($deno$/ops/dispatch_json.ts:98:10)
    at async fetch ($deno$/web/fetch.ts:591:27)

it works outside of docker-compose, the only difference I made is, in docker-compose, i use dynamodb, but it uses localhost outside of docker-compose,
