Preface

As a system engineer, you can deploy a Red Hat Process Automation Manager immutable server environment on Red Hat OpenShift Container Platform to provide an infrastructure to execute services, process applications, and other business assets. You can use standard integration tools to manage the immutable Process Server image. You can create new server images to add and update the business assets.

Prerequisites

  • Red Hat OpenShift Container Platform version 3.11 is deployed.
  • At least four gigabytes of memory are available in the OpenShift cluster/namespace.

    • If you do not deploy monitoring infrastructure but only deploy an immutable Process Server, three gigabytes can be sufficient.
  • 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 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:

    • Each immutable server deployment includes a replicated set of Process Server pods, which, by default, requires one 1Gi PV for the database. You can change the database PV size in the template parameters. You can deploy multiple immutable servers; each requires a separate database PV. This requirement does not apply if you use an external database server.
    • If you deploy the immutable monitoring template, two 64Mi PVs are also required (one for Business Central Monitoring and one for Smart Router).
  • If you intend to deploy the immutable monitoring template, 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 Online volume plug-ins, see Access Modes.

    Important

    ReadWriteMany mode is not supported on OpenShift Online and OpenShift Dedicated.

Note

Since Red Hat Process Automation Manager version 7.5, support for Red Hat OpenShift Container Platform 3.x is deprecated, including using templates to install Red Hat Process Automation Manager. This functionality will be removed in a future release.

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.
