Chapter 2. Comparison: Intelligent Process Server for OpenShift and Intelligent Process Server

This topic details the differences between Intelligent Process Server for OpenShift and the full, non-PaaS release of JBoss BPMS, and provides instructions specific to running and configuring Intelligent Process Server for OpenShift.
Documentation for other Intelligent Process Server functionality not specific to Intelligent Process Server for OpenShift can be found in the Red Hat JBoss BPM Suite documentation on the Red Hat Customer Portal.

2.1. Functionality Differences for Intelligent Process Server for OpenShift images

There are several major functionality differences between the regular release of Intelligent Process Server and the Intelligent Process Server for OpenShift:

  • Intelligent Process Server for OpenShift extends the OpenShift EAP image, and any capabilities or limitations it has are also found in the Intelligent Process Server for OpenShift.
  • Business Central is not included in Intelligent Process Server for OpenShift. To connect to the Intelligent Process Server web console, click the Open Java Console button in OpenShift 3.2.
  • There is no support for authoring any content through the BPMS Console or API.
  • There is no support for the Singleton strategy for maintaining a single instance of the RuntimeEngine.

2.2. Version Compatibility and Support

For more information on OpenShift image version compatibility, see the xPaaS part of the OpenShift and Atomic Platform Tested Integrations page.

2.3. Deprecated Image Streams and Application Templates for Intelligent Process Server for OpenShift

Important

The Intelligent Process Server for OpenShift image version number 6.2 is deprecated and it will no longer receive updates of image and application templates.

The Intelligent Process Server for OpenShift image version number 6.3 is deprecated and it will no longer receive updates of image and application templates.

It is recommended to use the version 6.4 of Intelligent Process Server for OpenShift image and application templates to deploy new applications.

2.4. Managing Intelligent Process Server for OpenShift

As Intelligent Process Server for OpenShift is built off EAP for OpenShift, the JBoss EAP Management CLI is accessible from within the container for troubleshooting purposes.

  1. First open a remote shell session to the running pod: 

    $ oc rsh <pod_name>

  2. Then run the following from the remote shell session to launch the JBoss EAP Management CLI: 

    $ /opt/eap/bin/jboss-cli.sh
Warning

Any configuration changes made using the JBoss EAP Management CLI on a running container will be lost when the container restarts.

2.5. Security in Intelligent Process Server for OpenShift

Access is limited to users with the kie-server authorization role. A user with this role can be specified via the KIE_SERVER_USER and KIE_SERVER_PASSWORD environment variables.

Note

The HTTP/REST endpoint is configured to only allow the execution of KIE containers and querying of KIE Server resources. Administrative functions like creating or disposing Containers, updating ReleaseIds or Scanners, etc. are restricted. The JMS endpoint currently does not support these restrictions. In the future, more fine-grained security configuration should be available for both endpoints.

2.6. Initial Setup

The Tutorials in this guide follow on from and assume an OpenShift instance similar to that created in the OpenShift Primer.
