Preface

Prerequisites

• A Red Hat OpenShift Container Platform environment is available. The Operator is supported on Red Hat OpenShift Container Platform version 4.1 and 4.2.
• At least four gigabytes of memory are available in the OpenShift environment.
• The OpenShift project for the deployment is created.
• You are logged in to the project using the OpenShift 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 deployed replicated set of Process Server pods, by default, requires one 1Gi PV for the database. You can change the database PV size. You can deploy multiple immutable servers; each requires a separate database PV. This requirement does not apply if you use an external database server.
  • By default, Business Central requires one 1Gi PV. You can change the PV size for Business Central persistent storage.
  • Business Central Monitoring requires one 64Mi PV.
  • Smart Router requires one 64Mi PV.

• If you intend to scale any of the Business Central or Business Central Monitoring pods, 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.

  Important

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