[AWS Lab] CloudFormation – DynamoDB

In this lab, we will learn how to create a DynamoDB table using CloudFormation.

    1. Create a Template File

    • Please review the following YAML template file and save it “myDynamoDB.yaml“.
    AWSTemplateFormatVersion: "2010-09-09"
Description: "AWS CloudFormation Sample Template DynamoDB."

Parameters:
  ReadCapacityUnits:
    Description: "Provisioned read throughput"
    Type: "Number"
    Default: "1"
    MinValue: "1"
    MaxValue: "1000"
    ConstraintDescription: "must be between 1 and 1000"
  WriteCapacityUnits:
    Description: "Provisioned write throughput"
    Type: "Number"
    Default: "1"
    MinValue: "1"
    MaxValue: "10000"
    ConstraintDescription: "must be between 1 and 1000"

Resources:
  OrdersTable:
    Type: AWS::DynamoDB::Table
    Properties:
      TableName: "Orders"
      AttributeDefinitions:
        - AttributeName: "OrderId"
          AttributeType: "N"
        - AttributeName: "Item"
          AttributeType: "S"
        - AttributeName: "Price"
          AttributeType: "N"
        - AttributeName: "OrderDate"
          AttributeType: "S"  
      KeySchema:
        - AttributeName: "OrderId"
          KeyType: "HASH"
        - AttributeName: "Item"
          KeyType: "RANGE"
      ProvisionedThroughput:
        ReadCapacityUnits: !Ref ReadCapacityUnits
        WriteCapacityUnits: !Ref WriteCapacityUnits
      LocalSecondaryIndexes:
        - IndexName: "PriceIndex"
          KeySchema:
            - AttributeName: "OrderId"
              KeyType: "HASH"
            - AttributeName: "Price"
              KeyType: "RANGE"
          Projection:
            ProjectionType: "KEYS_ONLY"
      GlobalSecondaryIndexes:
        - IndexName: "OrderDateIndex"
          KeySchema:            
            - AttributeName: "OrderDate"
              KeyType: "HASH"
            - AttributeName: "OrderId"
              KeyType: "RANGE"
          Projection:
            ProjectionType: "ALL"
          ProvisionedThroughput:
            ReadCapacityUnits: !Ref ReadCapacityUnits
            WriteCapacityUnits: !Ref WriteCapacityUnits
 
Outputs:
  TableName:
      Value: !Ref OrdersTable
      Description: "Name of the newly created DynamoDB table"

    2. CloudFormation – Create a Stack

    • Click “Create stack”
      • Click “with new resources (standard)“
    • Create Stack
      • Check “Template is ready“
      • Check “Upload a template file”
        • Choose “myDynamoDB.yaml“
      • Click “View In Designer”
        • Click the “Validate Template” button
        • Click the “Create Stack” button – cloud shape
      • Click “Next“
    • Stack Details
      • Stack name: “DynamoDBStack“
      • parameters
        • “ReadCapacityUnits“: 2
        • “WriteCapacityUnits“: 2
      • Click “Next“
    • Stack Options
      • Accept all defaults
      • Click “Next“
    • Review
      • Click “Submit“

    3. CloudFormation – Create Resources

    • The stack is creating a DynamoDB table with indexes.
      • Wait until the process completes.
    • Check the “Events” tab
    • Check the “Outputs” tab
      • You can see the table name.
    • Check the “Resources” tab
      • Navigate to the DynamoDB table and check the properties
