⚙️ Config Service

Github: github.com/le-minh-duc-dev/chat-system-config-server.git

📘 Overview

The Config Service acts as a centralized configuration server that manages and serves externalized configuration for all microservices in the system. It allows dynamic updates and consistent configurations across environments (development, staging, production), supporting both versioning and Git-backed configuration.

This service is built using Spring Cloud Config Server, which reads configurations from a Git repository and exposes them via HTTP endpoints to client applications.

🚀 Responsibilities

Centralize and externalize configurations for all services.
Support environment-specific configurations.
Enable dynamic refresh of configurations using Spring Cloud Bus (optional).
Secure configuration access via role-based permissions (optional).

🛠️ Technologies

Spring Boot
Spring Cloud Config Server
GitHub (for configuration storage)

🔧 How Clients Connect

Each microservice (e.g., chat-service, auth-service, etc.) connects to the Config Service by setting:

spring:
  config:
    import: optional:configserver:http://localhost:8080

And by setting the service name so it pulls the corresponding config:

spring:
  application:
    name: chat-service

This will fetch chat-service.yml or chat-service-{profile}.yml chat-service.properties or chat-service-{profile}.properties from the Git repo.
