Red Hat Summit第2章 Project deployment in Business Central
You can use Business Central to develop your business assets and services and to manage Decision Servers configured for project deployment. When your project is developed, you can build the project in Business Central and deploy it automatically to the Decision Server. To enable automatic deployment, Business Central includes a built-in Maven repository. From Business Central, you can start, stop, or remove the deployment units (KIE containers) that contain the services and their project versions that you have built and deployed.
You can also connect several Decision Servers to the same Business Central instance and group them into different server configurations (in Menu
For example, you could have test servers in the Test configuration and production servers in a Production configuration. As you develop business assets and services in a project, you deploy the project on the Test server configuration and then, when a version of the project is sufficiently tested, you can deploy it on the Production server configuration. In this case, to keep developing the project, change the version in the project settings. Then the new version and the old version are seen as different artifacts in the built-in Maven repository. You can deploy the new version on the Test server configuration and keep running the old version on the Production server configuration. This deployment process is simple but has significant limitations. Notably, there is not enough access control: a developer can deploy a project directly into a production environment.
You cannot move a Decision Server into a different server configuration using Business Central. You must change the configuration file of the server to change the server configuration name for it.
2.1. Configuring a Decision Server to connect to Business Central
If a Decision Server is not already configured in your Red Hat Decision Manager environment, or if you require additional Decision Servers in your Red Hat Decision Manager environment, you must configure a Decision Server to connect to Business Central.
If you are deploying Decision Server on Red Hat OpenShift Container Platform, see Deploying a Red Hat Decision Manager authoring or managed server environment on Red Hat OpenShift Container Platform for instructions about configuring it to connect to Business Central.
Prerequisites
- Decision Server is installed. For installation options, see Planning a Red Hat Decision Manager installation.
Procedure
-
In your Red Hat Decision Manager installation directory, navigate to the
standalone-full.xmlfile. For example, if you use a Red Hat JBoss EAP installation for Red Hat Decision Manager, go to$EAP_HOME/standalone/configuration/standalone-full.xml. Open
standalone-full.xmland under the<system-properties>tag, set the following properties:- org.kie.server.controller.user: The user name of a user who can log in to the Business Central.
- org.kie.server.controller.pwd: The password of the user who can log in to the Business Central.
-
org.kie.server.controller: The URL for connecting to the API of Business Central. Normally, the URL is
http://<centralhost>:<centralport>/decision-central/rest/controller, where<centralhost>and<centralport>are the host name and port for Business Central. If Business Central is deployed on OpenShift, removedecision-central/from the URL. -
org.kie.server.location: The URL for connecting to the API of Decision Server. Normally, the URL is
http://<serverhost>:<serverport>/kie-server/services/rest/server, where<serverhost>and<serverport>are the host name and port for Decision Server. - org.kie.server.id: The name of a server configuration. If this server configuration does not exist in Business Central, it is created automatically when Decision Server connects to Business Central.
Example:
<property name="org.kie.server.controller.user" value="central_user"/> <property name="org.kie.server.controller.pwd" value="central_password"/> <property name="org.kie.server.controller" value="http://central.example.com:8080/decision-central/rest/controller"/> <property name="org.kie.server.location" value="http://kieserver.example.com:8080/kie-server/services/rest/server"/> <property name="org.kie.server.id" value="production-servers"/>- Start or restart the Decision Server.
