Preface

As a system engineer, you can deploy a Red Hat Process Automation Manager freeform managed server environment on Red Hat OpenShift Container Platform to provide an infrastructure to execute services, process applications, and other business assets. You can deploy any number of managed KIE Servers and control them using the same Business Central Monitoring. You can add and remove the KIE Servers as necessary; Business Central Monitoring establishes a connection to them automatically. You can also use the same Business Central Monitoring instance to monitor immutable KIE Servers.

Prerequisites

  • Red Hat OpenShift Container Platform version 3.11 is deployed.
  • At least four gigabytes of memory are available in the OpenShift cluster/namespace.
  • The OpenShift project for the deployment is created.
  • You are logged in to the project using the oc command. For more information about the oc command-line tool, see the OpenShift Container Platform CLI Reference. If you want to use the OpenShift Web console to deploy templates, you must also be logged on using the Web console.

  • Dynamic persistent volume (PV) provisioning is enabled. Alternatively, if dynamic PV provisioning is not enabled, enough persistent volumes must be available. By default, the deployed components require the following PV sizes:

    • Business Central Monitoring requires a 64Mi PV.
    • Each KIE Server deployment by default requires one 1Gi PV for the database. You can change the database PV size in the template parameters. If you deploy multiple separate KIE Servers, each of the servers requires a separate database PV. This requirement does not apply if you use an external database server.
  • Your OpenShift environment supports persistent volumes with ReadWriteMany mode. If your environment does not support this mode, you can use NFS to provision the volumes. For information about access mode support in OpenShift public and dedicated clouds, see Access Modes.
Note

Since Red Hat Process Automation Manager version 7.5, images and templates for Red Hat OpenShift Container Platform 3.x are deprecated. These images and templates do not get new features, but remain supported until the end of full support for Red Hat OpenShift Container Platform version 3.x. For more information about the full support lifecycle phase for Red Hat OpenShift Container Platform version 3.x, see Red Hat OpenShift Container Platform Life Cycle Policy (non-current versions).

Note

Do not use Red Hat Process Automation Manager templates with Red Hat OpenShift Container Platform 4.x. To deploy Red Hat Process Automation Manager on Red Hat OpenShift Container Platform 4.x, see the instructions in Deploying a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform using Operators.
