It will then spin a DynamoDB container within the same directory and make a DynamoDB instance available for usage. Once you have created the file with the above script, open the terminal/command line interface (CLI) and browse to the directory where you have created docker-compose.yaml file. dynamodb_data:/home/thegeekyasian/dynamodblocal/dataĬommand: -jar DynamoDBLocal.jar -sharedDb -dbPath /home/thegeekyasian/dynamodblocal/data/

Local dynamodb unable to create table install#

Install DynamoDBĬopy the below script and place it on your local machine in an empty file names docker-compose.yaml version: '2' To be able to set up DynamoDB locally, you must have Docker installed on your local machine.

Here is a quick tutorial how you can do that: Prerequisite

It turned out to the best thing! Long story short, I was able to set up DynamoDB locally using Docker. That is when I found out that Amazon Web Services (AWS) provides a downloadable version of DynamoDB. He didn’t feel like providing me a DynamoDB instance on his AWS account, (security concerns, yeaahh!!) and I was too lazy to get one by myself. The client I was working for expected me to have a separate DynamoDB account.

Local dynamodb unable to create table free#

Since the free port can be different each time you trigger this code, you need to retrieve the port.Lets have a look on how we can set up DynamoDB locally in 5 minutes!įor one of my recent projects, I had to use DynamoDB. Testcontainers will automatically start the given Docker container by choosing a free port on your system and mapping it to 8000 (DynamoDB Local’s default port).

Local dynamodb unable to create table code#

This code is using JUnit 4’s annotation to trigger the Testcontainers start process. New GenericContainer("amazon/dynamodb-local:1.11.477") mapping will be wrong -> see the docs: static GenericContainer dynamoDBLocal = make sure to specify the exposed port as 8000, otherwise the port To start a DynamoDB Local instance, simply add the following code to your tests: // This declaration will start a DynamoDB Local Docker container before the unit tests run -> It allows you starting Docker containers, e.g.

For this case, Testcontainers is a really good library that can be integrated into your automated tests. Since you don’t want to start a Docker container each time you run a unit test, you need to automate this step. Automatically Start DynamoDB Local Before Running The Tests If you want, you can further customize DynamoDB Local as described in the usage notes. withEndpointConfiguration(endpointConfig) Then, you only need to adapt the DynamoDB client from the AWS SDK and point it to the localhost endpoint: AwsClientBuilder.EndpointConfiguration endpointConfig =ĪwsClientBuilder.EndpointConfiguration(" "us-west-2") ĪmazonDynamoDB dynamodb = AmazonDynamoDBClientBuilder.standard() It spins up a Docker container and makes DynamoDB available on port 8000. Running it locally only requires this command: docker run -p 8000:8000 amazon/dynamodb-local For the next sections the DynamoDB Local Docker image is used.

This blog post explains all required steps with Java and helps with typical pitfalls.Īll the code is available in a Bitbucket repository providing various examples how to combine the approaches below. Unfortunately, setting up DynamoDB Local and combining it with Testcontainers and Bitbucket Pipelines in your automated tests can lead to some headache. This makes unit testing cloud services a lot easier if you’re relying on DynamoDB. Thankfully DynamoDB provides a local version of their database. Running cloud services on your local machine is often a problem because there is no local version available.
