Nacos Server 多数据源镜像

镜像概述

本镜像基于 https://github.com/nacos-group/nacos-plugin 构建，通过修改Application.properties的注入方式，实现了对多数据源配置的适配。主要用于提供支持多数据源的Nacos服务注册与配置中心功能。

核心功能与特性

• 多数据源支持：优化配置注入方式，适配多数据源场景
• PostgreSQL兼容：默认支持PostgreSQL数据库连接
• 认证功能：集成Nacos认证机制，支持身份验证与授权
• 完整保留Nacos核心功能：包含服务发现、配置管理、动态配置等原生功能
• 灵活部署：支持单机模式、集群模式部署

使用场景

• 微服务架构中的服务注册与发现中心
• 需要多数据源管理的配置中心场景
• 对数据存储有高可用、多源需求的企业级应用
• Kubernetes、Docker Compose等容器化环境部署

使用方法

1. Docker Run 部署

docker
docker run -it --name nacos-quick \

-p 8848:8848 \
-p 9848:9848 \
-p 8080:8080 \
-d fuhouyu/nacos-server:3.0.3-postgresql

2. Docker Compose 部署

      DB_USER: ${database_username}
      DB_PASSWORD: ${database_password}
      NACOS_AUTH_ENABLE: "true"
      DRIVER_CLASS_NAME: "org.postgresql.Driver"
    ports:
      - "8848:8848"  # Nacos服务端口
      - "9848:9848"  # 客户端RPC端口
