Architecture HighLights
- All registration information will be stored in NacosSync DB.
- Multiple NacosSync instances will perform the same job.
- Multiple NacosSync instances ensure high availability.
- Multiple NacosSync instances performing the same job ensure the simplicity.
- NacosCluster target will dedup the synchronization information from Nacos.
Quick Start:
- Swagger API: http://127.0.0.1:8083/swagger-ui.html#/

Initialize The DB
The default is Mysql database, which can support other relational databases
- Build db schema, the default schema name nacos_sync.
- Tables do not need to be created separately, which is conducive to hibernate's automatic table creation function.
- If the automatic table creation fails, you can build the table nacosSync.sql, the table statement is in the bin folder.
DB Configuration
In the bin folder, application.properties:
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/nacos_sync?characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=root
Start Server
$ nacosSync/bin:
sh startup.sh start
Admin Console
http://127.0.0.1:8083/#/serviceSync
Advanced Configuration
Full Synchronization from Zookeeper to Nacos (Dubbo)
When “*” is entered in the “Service Name” field of this form, it will fully synchronize all services from Zookeeper to Nacos, but only when using Dubbo.
Full Synchronization from Nacos to Nacos
When “All” is entered in the “Service Name” field of this form, it will automatically synchronize all registered services within the default group of the current cluster.
This description explains the functionality clearly for English-speaking users.
