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, enough persistent volumes must be available. By default, the following sizes are required:

  • The replicated set of Process Server pods requires one 1Gi PV for the database by default. You can change the database PV size in the template parameters. This requirement does not apply if you use an external database server.
  • Business Central requires one 1Gi PV by default. You can change the PV size for Business Central persistent storage in the template parameters.

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

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