Preface

Prerequisites

• At least four gigabytes of memory must be available in the OpenShift cluster/namespace.
• The OpenShift project for the deployment must be created.
• You must be 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 must be enabled. Alternatively, if dynamic PV provisioning is not enabled, a sufficient persistent volume must be available. By default, Decision Central requires one 1Gi PV. You can change the PV size for Decision Central persistent storage in the template parameters.

• If you intend to use the Authoring High Availability template, which scales the Decision Central pod:

  • The image streams for Red Hat AMQ version 7.1 or later must be available in your OpenShift environment.
  • Your OpenShift environment must support persistent volumes with ReadWriteMany mode. For information about access mode support in OpenShift Online volume plug-ins, see Access Modes.
