+# DynamoDB
+
+Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+## 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
+
+<!--codeinclude-->
+[Creating a DynamoDB container](../../modules/dynamodb/examples_test.go) inside_block:runDynamoDBContainer
+<!--/codeinclude-->
+
+## Module Reference
+
+### Run function
+
+- Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+The DynamoDB module exposes one entrypoint function to create the DynamoDB container, and this function receives three parameters:
+
+```golang
+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.
+
+### Container Options
+
+When starting the DynamoDB container, you can pass options in a variadic way to configure it.
+
+#### Image
+
+If you need to set a different DynamoDB Docker image, you can set a valid Docker image as the second argument in the `Run` function.
+E.g. `Run(context.Background(), "amazon/dynamodb-local:2.2.1")`.
+
+{% include "../features/common_functional_options.md" %}
+
+#### WithSharedDB
+
+- Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+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
+
+- Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+You can turn off telemetry when starting the DynamoDB container, using the option `WithDisableTelemetry`.
+
+### Container Methods
+
+The DynamoDB container exposes the following methods:
+
+#### ConnectionString
+
+- Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+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.
+
+<!--codeinclude-->
+[Creating a client](../../modules/dynamodb/dynamodb_test.go) inside_block:createClient
+<!--/codeinclude-->
+
+The above example uses `github.com/aws/aws-sdk-go-v2/service/dynamodb` to create a client and connect to the DynamoDB container.
