Admin Overall Architecture and Installation Steps

Mon, 01 Jan 0001 00:00:00 +0000

Reviewing the overall architecture of the Dubbo service governance system, Admin is a core component in the service governance control plane, responsible for service governance and visualization display for microservice clusters.

Admin Deployment Architecture

Overall, the Admin deployment architecture is divided into the following parts:

The Admin main process, including service discovery metadata management, a visualization console, security authentication policy control, and other customized service governance capabilities.
Strong dependency components, including Mysql database, registration/configuration/metadata centers (which can be Kubernetes, Nacos, Zookeeper, etc.)
Optional dependency components, including Prometheus, Grafana, Zipkin, etc.

Install Admin

Dubboctl Installation

Download

Currently, Dubboctl is not formally released and can be tried as follows. Pull Dubbo Admin and compile Dubboctl

Admin Service Query

The Admin supports a visual display of the status of the Dubbo microservice cluster, making it easy for users to globally grasp the distribution of applications, services, and instances in the cluster. Admin can also obtain more detailed information about a specific service through queries:

Home page cluster dashboard, displaying the overall distribution of cluster applications, services, instances, and overall traffic conditions.
Supports querying detailed information based on application name, service name (can include version & group), instance IP.
Supports automatic completion of service name/application name.
Supports viewing the details of a single service instance.

Overview of Admin Service Testing Features

Mon, 01 Jan 0001 00:00:00 +0000

The service testing feature is usually provided for developers of Dubbo services to perform self-testing on their published services. By simulating a real consumer process on the Admin console, calls can be made to the service provider, and the results can be verified to meet expectations.

Usage

Prepare Test Cases

Start the test case

You can refer to Quick Start to start a simple Dubbo service. For service testing, you only need to start the provider.

Introduction to Admin Service Mock Functionality

Mon, 01 Jan 0001 00:00:00 +0000

The mock functionality is designed to enhance the efficiency of microservices development and testing. It can short circuit remote calls initiated by the consumer side and return pre-set mock values in advance, allowing the consumer to continue development and testing even when no provider is available. Additionally, mocking can be used for quickly simulating test data responsible for return values and simulating server exceptions.

It is important to note that the mock capability is limited to the testing environment and should be avoided in the production environment.
