Hi everyone, i have this issue. When i run sls dynamodb migrate I have this error:

My serverless.yml

I am using docker and this is my configuration:

Dockefile

FROM node:10-alpine

RUN mkdir -p /var/www/app
WORKDIR /var/www/app

RUN apk update && apk add openjdk7-jre
RUN npm install -g serverless

COPY . /var/www/app
RUN npm install
RUN npm run db:install

    command: npm run db:start
    networks:
      - net

The table is not being created. When I make a connection in the code it gives me timeout.

The docker container lifts well, and even the dynamodb shell.

My dynamodb client configuration:

'use strict';

const AWS = require('aws-sdk');

let options = {};

// connect to local DB if running offline
if (process.env.IS_OFFLINE) {
  options = {
    region: 'localhost',
    accessKeyId: 'xxxx',
    secretAccessKey: 'xxxx',
    endpoint: 'http://dynamodb:8000',
  };
}

const client = new AWS.DynamoDB.DocumentClient(options);
module.exports = client;

I don't know what I may be missing. Thanks!

Hi there, I have an example of using serverless-dynamodb-local together with docker here https://github.com/jch254/serverless-node-dynamodb-api. I am using Amazon's dynamodb-local image to run Dynamo in a separate container and the Serverless API in another.

Doing a similar thing and seem to be having the same issue 😞. @mapeveri have you manage to figure this out since?

have a look at this pr, it helped me. Just need to add the host as an option in index.js of the plugin https://github.com/99xt/serverless-dynamodb-local/pull/235
