If you are new to DynamoDb I highly recommend using NoSQL Workbench for DynamoDB to model, visualize, and query your new database.

Here is the fulling working code on my Github Enjoy - Cheers! Pro Tip This can also be useful if you just want to dump JSON into a database and do some aggregation. That's it! You now have an instance of DynamoDb running locally! You can use this to persist data for your latest application or just spin it up to toy around with it. Start Your Database! docker-compose up dev is used to tell the jar to use the current directory for the shared database. The -sharedDb option simply creates a shared database inside the container. We are using Java's -jar command to execute the DynamoDBLocal jar file.

command - This is the command that is run when we start the container.

This allows the data in your database to persist after you stop and restart your container!

We are creating a volume named dynamodata and initializing it to an empty object.

volumes - Volumes are created and managed by Docker.

ports - Here we are simply mapping port 8000 on our host system to port 8000 inside the container.

A good use case for multiple services would be if you want to start up an Express server and a DynamoDb instance for your local API to interact with.

services - You can have docker start multiple containers for full-stack applications.

Newer versions add improved capabilities.

version - This is the version of docker-compose to use.

yml version: '3.7' services:Д¬ommand: '-jar DynamoDBLocal.jar -sharedDb -dbPath. Let's get started by creating a docker-compose.yml file. Create DockerfileДЄmazon has been kind enough to create a DynamoDb Docker image for us! We will be using the amazon/dynamodb-local image. However, for this tutorial that will not be necessary. Since DynamoDb is an AWS service you would first need to create an AWS account.

I typically start these posts off by saying to install the framework locally.

TLDR: Here is the fulling working code on my Github. DynamoDB exposes a similar data model to and derives its name from Dynamo, but has a different underlying implementation.

I will be starting a series on DynamoDb soon so stay tuned!ДЄmazon DynamoDB is a fully managed proprietary NoSQL database service that supports key-value and document data structures and is offered by as part of the Amazon Web Services portfolio. Also, if you do plan on using DynamoDb in production this is an easy way to get started without needing to pay AWS. Since DynamoDb is a NoSQL database it gives developers a lot of flexibility.

And should I mention that it is free of charge We also donвЂ™t need to worry about the provisioned. One of the benefits of having a local Dy n amoDB instance is that you can test your application code that interacts with DynamoDB locally instead of pointing to a real DynamoDB in AWS cloud. This can very useful for prototyping an application where you need to persist some data. Benefits of having a local DynamoDB instance. I am going to show you how you can use Docker to spin up a DynamoDb. This is going to be a very quick tutorial.
