Preface

As a system engineer, you can deploy a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform to provide an infrastructure to develop or execute processes and other business assets. You can use the Automation Broker to deploy the environment in an interactive process, setting all parameters as necessary. A Red Hat Process Automation Manager Ansible Playbook for the Automation Broker is available.

Prerequisites

  • At least four gigabytes of memory must be available in the OpenShift environment.
  • The OpenShift Ansible Broker must be installed and started in the OpenShift environment.
  • The OpenShift project for the deployment must be created.

  • You must be logged in to the project using the OpenShift web console and using the oc command.

    • Administrator access is required if Red Hat Process Automation Manager 7.2 image streams are not already available in the OpenShift enfironment.

  • 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:

    • Each deployed replicated set of Process Server pods, by default, requires one 1Gi PV for the database. You can change the database PV size in the playbook 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.
    • By default, Business Central requires one 1Gi PV. You can change the PV size for Business Central persistent storage in the playbook parameters.
    • 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.

    Important

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