Nacos: Dynamic Naming and Configuration Service

---

What does it do

Nacos (official site: nacos.io) is an easy-to-use platform designed for dynamic service discovery and configuration and service management. It helps you to build cloud native applications and microservices platform easily.

Service is a first-class citizen in Nacos. Nacos supports almost all type of services，for example，Dubbo/gRPC service, Spring Cloud RESTFul service or Kubernetes service.

Nacos provides four major functions.

• Service Discovery and Service Health Check

  Nacos makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. Nacos also provides real-time health checks of services to prevent sending requests to unhealthy hosts or service instances.

• Dynamic Configuration Management

  Dynamic Configuration Service allows you to manage configurations of all services in a centralized and dynamic manner across all environments. Nacos eliminates the need to redeploy applications and services when configurations are updated, which makes configuration changes more efficient and agile.

• Dynamic DNS Service

  Nacos supports weighted routing, making it easier for you to implement mid-tier load balancing, flexible routing policies, flow control, and simple DNS resolution services in the production environment within your data center. It helps you to implement DNS-based service discovery easily and prevent applications from coupling to vendor-specific service discovery APIs.

• Service and MetaData Management

  Nacos provides an easy-to-use service dashboard to help you manage your services metadata, configuration, kubernetes DNS, service health and metrics statistics.

Quick Start

It is super easy to get started with your first project.

Deploying Nacos on cloud

You can deploy Nacos on cloud, which is the easiest and most convenient way to start Nacos.

Use the following Nacos deployment guide to see more information and deploy a stable and out-of-the-box Nacos server.

Start by the provided startup package

Step 1: Download the binary package

You can download the package from the latest stable release.

Take release nacos-server-1.0.0.zip for example:

unzip nacos-server-1.0.0.zip
cd nacos/bin 

Step 2: Start Server

On the Linux/Unix/Mac platform, run the following command to start server with standalone mode:

sh startup.sh -m standalone

On the Windows platform, run the following command to start server with standalone mode. Alternatively, you can also double-click the startup.cmd to run NacosServer.

startup.cmd -m standalone
