Deploying DynamoDB locally on your computer
- Download locally
-
DynamoDB local is provided as an executable
.jar
file. The application runs on Windows, Linux, macOS, and other platforms that support Java.Follow these steps to set up and run DynamoDB on your computer.
Note
DynamoDB local v1.20 and greater is required for use on M1 and newer Apple processors.
To set up DynamoDB on your computer
Download DynamoDB for free from one of the following locations.

DynamoDB is also available as part of the AWS Toolkit for Eclipse. For more information, see AWS Toolkit for Eclipse
. Important
To run DynamoDB on your computer, you must have the Java Runtime Environment (JRE) version 8.x or newer. The application doesn't run on earlier JRE versions.
-
After you download the archive, extract the contents and copy the extracted directory to a location of your choice.
To start DynamoDB on your computer, open a command prompt window, navigate to the directory where you extracted
DynamoDBLocal.jar
, and enter the following command.java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb
Note
If you're using Windows PowerShell, be sure to enclose the parameter name or the entire name and value like this:
java -D"java.library.path=./DynamoDBLocal_lib" -jar DynamoDBLocal.jar
DynamoDB processes incoming requests until you stop it. To stop DynamoDB, press Ctrl+C at the command prompt.
DynamoDB uses port 8000 by default. If port 8000 is unavailable, this command throws an exception. For a complete list of DynamoDB runtime options, including
-port
, enter this command.java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -help
-
Before you can access DynamoDB programmatically or through the AWS Command Line Interface (AWS CLI), you must configure your credentials to enable authorization for your applications. Downloadable DynamoDB requires any credentials to work, as shown in the following example.
AWS Access Key ID: "fakeMyKeyId" AWS Secret Access Key: "fakeSecretAccessKey"
You can use the
aws configure
command of the AWS CLI to set up credentials. For more information, see Using the AWS CLI. -
Start writing applications. To access DynamoDB running locally with the AWS CLI, use the
--endpoint-url
parameter. For example, use the following command to list DynamoDB tables.aws dynamodb list-tables --endpoint-url http://localhost:8000
- Docker

The downloadable version of Amazon DynamoDB is available as a Docker image. For more information, see dynamodb-local
. For an example of using DynamoDB local as part of a REST application built on the AWS Serverless Application Model (AWS SAM), see SAM DynamoDB application for managing orders
. This sample application demonstrates how to use DynamoDB local for testing. If you want to run a multi-container application that also uses the DynamoDB local container, use Docker Compose to define and run all the services in your application, including DynamoDB local.
To install and run DynamoDB local with Docker compose:
-
Download and install Docker desktop
. -
Copy the following code to a file and save it as
docker-compose.yml
.version: '3.8' services: dynamodb-local: command: "-jar DynamoDBLocal.jar -sharedDb -dbPath ./data" image: "amazon/dynamodb-local:latest" container_name: dynamodb-local ports: - "8000:8000" volumes: - "./docker/dynamodb:/home/dynamodblocal/data" working_dir: /home/dynamodblocal
If you want your application and DynamoDB local to be in separate containers, use the following yaml file.
version: '3.8' services: dynamodb-local: command: "-jar DynamoDBLocal.jar -sharedDb -dbPath ./data" image: "amazon/dynamodb-local:latest" container_name: dynamodb-local ports: - "8000:8000" volumes: - "./docker/dynamodb:/home/dynamodblocal/data" working_dir: /home/dynamodblocal app-node: depends_on: - dynamodb-local image: amazon/aws-cli container_name: app-node ports: - "8080:8080" environment: AWS_ACCESS_KEY_ID: 'DUMMYIDEXAMPLE' AWS_SECRET_ACCESS_KEY: 'DUMMYEXAMPLEKEY' command: dynamodb describe-limits --endpoint-url http://dynamodb-local:8000 --region us-west-2
This docker-compose.yml script creates an
app-node
container and adynamodb-local
container. The script runs a command in theapp-node
container that uses the AWS CLI to connect to thedynamodb-local
container and describes the account and table limits.To use with your own application image, replace the
image
value in the example below with that of your application.version: '3.8' services: dynamodb-local: command: "-jar DynamoDBLocal.jar -sharedDb -dbPath ./data" image: "amazon/dynamodb-local:latest" container_name: dynamodb-local ports: - "8000:8000" volumes: - "./docker/dynamodb:/home/dynamodblocal/data" working_dir: /home/dynamodblocal app-node: image:
location-of-your-dynamodb-demo-app:latest
container_name: app-node ports: - "8080:8080" depends_on: - "dynamodb-local" links: - "dynamodb-local" environment: AWS_ACCESS_KEY_ID: 'DUMMYIDEXAMPLE' AWS_SECRET_ACCESS_KEY: 'DUMMYEXAMPLEKEY' REGION: 'eu-west-1'Note
The YAML scripts require that you specify an AWS access key and an AWS secret key, but they are not required to be valid AWS keys for you to access DynamoDB local.
-
Run the following command-line command:
docker-compose up

- Apache Maven
-
Follow these steps to use Amazon DynamoDB in your application as a dependency.
To deploy DynamoDB as an Apache Maven repository
-
Download and install Apache Maven. For more information, see Downloading Apache Maven
and Installing Apache Maven . -
Add the DynamoDB Maven repository to your application's Project Object Model (POM) file.
