Kuuhaku空白Spring PetClinic Microservices, mapped from the code.
The Spring PetClinic split into Spring Cloud microservices: a config server, discovery, an API gateway and the customers, vets and visits services. Kuuhaku read its source at commit a05f4fb, with no configuration and no hand-fixing, and found 7 services in Java and 14 connections: 14 over HTTP. Each one below says how it was found.
Services
Every repo or deployable the scanner found, with how many connections leave it and reach it.

Connections
config: the address is written in configuration (an env file, a compose file, a proxy route) and the call is matched to it. inferred: the call's path matches a route of the target and nothing contradicts it. Call sites count the places in the code that make the call.
