Nowadays, when microservices quickly overcome the legacy style of monolithic applications, it’s only natural to deploy Business Decision Models as Decision Microservices. We’ve just published a new tutorial that in a step-by-step manner explains how to convert OpenRules-based decision models, created and tested by business users, to decision microservices with Spring Boot and then containerize them with Docker. Following the tutorial you will learn how to:

• “Mavenize” the standard OpenRules configuration
• Create a simple Maven project in Eclipse which will be used to invoke OpenRules-based service “Vacation Days” with business logic represented in Excel decision tables
• Test it from Java
• Convert this decision service to a simple REST web application built using Spring Boot and test it with POSTMAN using JSON and Java
• Containerize this decision service using Docker and test it using POSTMAN and/or a Java-based client.
• Add more decision services.

In the end, you will be ready to create and containerize your own OpenRules decision services. For your convenience, we added a new workspace “openrules.services” to the standard evaluation version. Link
