Connecting to DynamoDB

[justinmchase]

I also connect to dynamo from my local lambda and it works for me, so it is possible. I use docker-compose to setup links because its easier but from first glance based on what you have there you need to expose the port on your dynamodb container and you also need to create a network and have them both join it:

docker network create test
docker run -d --name dynamodb --network test -p 8000:8000 deangiberson/aws-dynamodb-local
docker run --links dynamodb:dynamodb --network test -v "$PWD":/var/task lambci/lambda index.handler

do you have resolution ?

The trick is to put them on the same network --network test

Thanks for this @justinmchase !! Also FYI for anyone trying to link to another docker container that is running an API via docker-compose:

docker network
docker network <container-network-name> inspect

Then you can use the IP address exposed by that command to test, for example, your Lambda API client locally from a container run by the the commands in the docker-lambda Readme.

Now with the new docker version use of --link is deprecated. Do you guys have any other approach for this?

AFAICT this isn't docker-lambda specific – general docker network settings should work here.
