ServiceID: trust-service
Trust computation service in the NIMBLE Microservice Infrastructure.
A prototype implementation of a NIMBLE trust computation service. The service computes a trust score for NIMBLE entities (e.g. providers/sellers) by evaluating their trust-related characteristics in regards to the trust expectations (trust policy defined by a platform manager)
Micro-service implementation using the Spring Boot framework and Java language.
Base configuration can be found at src/main/resources/application.properties and bootstrap.yml. Spring Cloud Config is used for central configuration management. A central configuration is hosted on https://github.com/nimble-platform/cloud-config and injected during startup.
For database configuration, Hibernate will create the database schema using JPA settings from bootstrap.yml and application.properties. However, before Hibernate creates the schema, the database (Postgres) must be installed and bootstrap.yml configured with the database connection details.
After trust-service is started and database schema created please execute the /sql/initialConfig.sql
The Trust Scoring and Ranking API is designed using the swagger.io editor (file: src/main/resources/api.yml) and the code generator for the Spring framework. The Maven plugin (swagger-codegen-maven-plugin) is used to generate defined interfaces automatically in each Maven build.
mvn clean spring-boot:run
It will be possible to run the service in docker environment from core cloud infrastructure, but this part is still under configuration.
Start the local example setup with
docker-compose upget
curl http://localhost:8081/version
http://localhost:8081/swagger-ui.html
Example calls will be added soon.
