By following these steps, you can easily master how to develop Dubbo services that comply with the Service Mesh architecture and deploy them to Kubernetes while integrating with Istio’s traffic management system. Here you can view the complete example source code.

1 Overall Goal

Deploy Dubbo applications to Kubernetes
Istio automatically injects Envoy and implements traffic interception
Implement traffic governance based on Istio rules

2 Basic Process and Working Principle

This example demonstrates how to deploy applications developed with Dubbo under the Istio framework to achieve automatic proxying of Dubbo services by Envoy. The overall architecture of the example is shown in the figure below.

You can easily deploy Dubbo services to a Kubernetes cluster by following the steps below, with the full code example available here.

1 Overall Goals

Deploy Dubbo applications to Kubernetes
Implement service discovery based on Kubernetes built-in Service
Integrate Dubbo applications with Kubernetes lifecycle

2 Basic Workflow

Create a Dubbo application (dubbo-samples-kubernetes)
Build container images and push to the image repository (dubbo-demo example image)
Deploy Dubbo Provider and Dubbo Consumer to Kubernetes
Verify service discovery and calls are normal

3 Detailed Steps

3.1 Environment Requirements

Ensure that the following environment is installed locally to provide container runtime, Kubernetes cluster, and access tools.
