AWS Amplify Console Updates Build image with SAM CLI and Custom Container Support

The default build image is now using Amazon Linux 2 with Node 10 and SAM CLI pre-installed. Custom containers allow developer to swap out the default container with their own build environment. At build time, Amplify will retrieve the Docker image from the container registry specified in the project configuration and use the environment to compile your source code, run your tests, and deploy your application. With the SAM CLI, developers can run SAM commands as part of their backend deployment without installing any other dependencies.
