Explanation

When terraform creates Exercism's infrastructure, it writes endpoints and DNS entries to DynamoDB. This gem allows you to trivially retrieve that data.

When running on AWS, simply ensure the machine has read-access to the relevant table (currently hardcoded to config).

Local AWS

This requires a local version of AWS to work. We use localstack for this. To start localstack use the following command:

docker run -dp 3042:8080 -p 3040:4566 -p 3041:4566 localstack/localstack
