🚀 DynamoDB Local with Docker Setup

This guide will help you get a local version of DynamoDB running with Docker and show you how to interact with it using the AWS CLI. Perfect for testing your app or playing around with AWS DynamoDB without any AWS charges.

🛠️ What's in this Setup?

We can use Docker Compose to launch two services:

1. DynamoDB Local

• Purpose: A local version of DynamoDB running inside a Docker container.
• Port: Accessible on your machine at http://localhost:8000.
• Why: You can test DynamoDB operations without connecting to the AWS Cloud.

2. AWS CLI (App-Node)

• Purpose: Runs the AWS CLI inside Docker to interact with DynamoDB Local.
• Command: Runs a sample command to check DynamoDB limits (describe-limits).
• Environment: Uses dummy AWS credentials (since you're working locally).

🏃 How to Get Started

1. Install Docker 🐳
   Make sure you’ve got Docker installed on your machine.
   👉 Get Docker here

2. Clone or Download this Repo
   Copy the docker-compose.yml file to your project folder.

3. Run the services
   Open a terminal, navigate to your project folder, and run:

   docker-compose up
   

   🟢 This starts DynamoDB on http://localhost:8000 and runs the AWS CLI command to check DynamoDB’s limits.

4. Check DynamoDB Tables
   In a new terminal, run this command to see the tables in your local DynamoDB:

   aws dynamodb list-tables --endpoint-url http://localhost:8000 --region us-west-2
   

   You should get an empty list if no tables are created yet.

5. Stop the services
   When you're done, shut everything down with:

   docker-compose down
