AWS 推出了 Amazon DynamoDB 的相容 Docker Image，讓開發者可以在本地端測試 DynamoDB 的 API：「Use Amazon DynamoDB Local More Easily with the New Docker Image」，在 amazon/dynamodb-local 這邊可以拉到，裡面其實是包 Java：
DynamoDB local is now available to download as a self-contained Docker image or a .jar file that can run on Microsoft Windows, Linux, macOS, and other platforms that support Java.
這樣在 Continuous Integration (CI) 的過程裡面也可以拉起 service 測試...
