Creating DynamoDB tables using the aws CLI

sudo apt-get install aws-cli

aws dynamodb --endpoint-url http://localhost:8000 create-table --table-name loyalty-service-member --attribute-definitions AttributeName=memberID,AttributeType=N AttributeName=namespace,AttributeType=S AttributeName=date,AttributeType=S --key-schema AttributeName=memberId,KeyType=HASH AttributeName=namespace,KeyType=RANGE --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

aws dynamodb --endpoint-url http://localhost:8000 create-table --table-name loyalty-service-order --attribute-definitions AttributeName=orderID,AttributeType=N AttributeName=namespace,AttributeType=S AttributeName=createDate,AttributeType=S --key-schema AttributeName=orderId,KeyType=HASH AttributeName=namespace,KeyType=RANGE --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

Note

If the DynamoDB endpoint is not provided as a command line parameter, a locally running DynamoDB is considered by default.

The AWS credentials and the AWS region must be provided even for the local DynamoDB. The AWS_ACCESS_KEY_ID and the region are used for naming the database. The AWS_SECRET_ACCESS_KEY is ignored but must be provided.
