DynamoDB

Since v0.34.0

Introduction

The Testcontainers module for DynamoDB.

Adding this module to your project dependencies

Please run the following command to add the DynamoDB module to your Go dependencies:

go get github.com/testcontainers/testcontainers-go/modules/dynamodb

Usage example

Creating a DynamoDB container

ctx := context.Background()

ctr, err := tcdynamodb.Run(ctx, "amazon/dynamodb-local:2.2.1")
defer func() {
    if err := testcontainers.TerminateContainer(ctr); err != nil {
        log.Printf("failed to terminate container: %s", err)
    }
}()
if err != nil {
    log.Printf("failed to run dynamodb container: %s", err)
    return
}

Module Reference

Run function

The DynamoDB module exposes one entrypoint function to create the DynamoDB container, and this function receives three parameters:

func Run(ctx context.Context, img string, opts ...testcontainers.ContainerCustomizer) (*DynamoDBContainer, error)
  • context.Context, the Go context.
  • string, the Docker image to use.
  • testcontainers.ContainerCustomizer, a variadic argument for passing options.

Image

Use the second argument in the Run function to set a valid Docker image. In example: Run(context.Background(), "amazon/dynamodb-local:2.2.1").

Container Options

When starting the DynamoDB container, you can pass options in a variadic way to configure it.

WithSharedDB

The WithSharedDB option tells the DynamoDB container to use a single database file. At the same time, it marks the container as reusable, which causes that successive calls to the Run function will return the same container instance, and therefore, the same database file.

WithDisableTelemetry

You can turn off telemetry when starting the DynamoDB container, using the option WithDisableTelemetry.

The following options are exposed by the testcontainers package.

Basic Options

Lifecycle Options

Files & Mounts Options

Build Options

Logging Options

Image Options

Networking Options

Advanced Options

Experimental Options

Container Methods

The DynamoDB container exposes the following methods:

ConnectionString

The ConnectionString method returns the connection string to the DynamoDB container. This connection string can be used to connect to the DynamoDB container from your application, using the AWS SDK or any other DynamoDB client of your choice.

Creating a client

var errs []error

hostPort, err := c.ConnectionString(context.Background())
if err != nil {
    errs = append(errs, fmt.Errorf("get connection string: %w", err))
}

cfg, err := config.LoadDefaultConfig(context.Background(), config.WithCredentialsProvider(credentials.StaticCredentialsProvider{
    Value: aws.Credentials{
        AccessKeyID:     "DUMMYIDEXAMPLE",
        SecretAccessKey: "DUMMYEXAMPLEKEY",
    },
}))
if err != nil {
    errs = append(errs, fmt.Errorf("load default config: %w", err))
}

require.NoError(t, errors.Join(errs...))

return dynamodb.NewFromConfig(cfg, dynamodb.WithEndpointResolverV2(&dynamoDBResolver{HostPort: hostPort}))

The above example uses github.com/aws/aws-sdk-go-v2/service/dynamodb to create a client and connect to the DynamoDB container.
