Creating Static Information for a Microservice

Function

This API is used to create static information for a microservice before registering a microservice instance. The registered instance is associated with the static information based on serviceId. One service corresponds to multiple instances.

serviceId can be customized. If serviceId is not customized, the system generates a random service ID.
