 The following guide describes how to setup the OpenTelemetry demo with Elastic Observability using [Docker compose](#docker-compose) or [Kubernetes](#kubernetes). This fork introduces several changes to the agents used in the demo:
 
-- The Java agent within the [Ad](../src/adservice/Dockerfile.elastic) and [Fraud Detection](../src/frauddetectionservice/Dockerfile.elastic) services have been replaced with the Elastic distribution of the OpenTelemetry Java Agent. You can find more information about the Elastic distribution in [this blog post](https://www.elastic.co/observability-labs/blog/elastic-distribution-opentelemetry-java-agent).
+- The Java agent within the [Ad](../src/adservice/Dockerfile.elastic), the [Fraud Detection](../src/frauddetectionservice/Dockerfile.elastic) and the [Kafka](../src/kafka/Dockerfile.elastic) services have been replaced with the Elastic distribution of the OpenTelemetry Java Agent. You can find more information about the Elastic distribution in [this blog post](https://www.elastic.co/observability-labs/blog/elastic-distribution-opentelemetry-java-agent).
 - The .NET agent within the [Cart service](../src/cartservice/src/Directory.Build.props) has been replaced with the Elastic distribution of the OpenTelemetry .NET Agent. You can find more information about the Elastic distribution in [this blog post](https://www.elastic.co/observability-labs/blog/elastic-opentelemetry-distribution-dotnet-applications).
 - The Elastic distribution of the OpenTelemetry Node.js Agent has replaced the OpenTelemetry Node.js agent in the [Payment service](../src/paymentservice/package.json). Additional details about the Elastic distribution are available in [this blog post](https://www.elastic.co/observability-labs/blog/elastic-opentelemetry-distribution-node-js).
