AWS LOCAL DYNAMODB INSTALL

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:Ĭommand: "-jar DynamoDBLocal.jar -sharedDb -dbPath.

Let's get started by creating a docker-compose.yml file. Create DockerfileĪmazon 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!Īmazon 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. This can very useful for prototyping an application where you need to persist some data. 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.
