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

  • 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 has been 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 following sizes are required:

    • 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. For information about access mode support in OpenShift Online volume plug-ins, see Access Modes.
