5.4. Installing Red Hat OpenShift Data Foundation Operator

You can install Red Hat OpenShift Data Foundation Operator using the Red Hat OpenShift Container Platform Operator Hub.

Prerequisites

Access to an OpenShift Container Platform cluster using an account with cluster-admin and Operator installation permissions.
You must have at least four worker nodes evenly distributed across two data centers in the Red Hat OpenShift Container Platform cluster.
For additional resource requirements, see Planning your deployment.

重要

When you need to override the cluster-wide default node selector for OpenShift Data Foundation, you can use the following command in command-line interface to specify a blank node selector for the openshift-storage namespace (create openshift-storage namespace in this case):
```
$ oc annotate namespace openshift-storage openshift.io/node-selector=
```
Taint a node as infra to ensure only Red Hat OpenShift Data Foundation resources are scheduled on that node. This helps you save on subscription costs. For more information, see How to use dedicated worker nodes for Red Hat OpenShift Data Foundation chapter in the Managing and Allocating Storage Resources guide.

Procedure

Log in to the OpenShift Web Console.
Click Operators OperatorHub.
Scroll or type OpenShift Data Foundation into the Filter by keyword box to search for the OpenShift Data Foundation Operator.
Click Install.
Set the following options on the Install Operator page:
1. Update Channel as stable-4.14.
2. Installation Mode as A specific namespace on the cluster.
3. Installed Namespace as Operator recommended namespace openshift-storage. If Namespace openshift-storage does not exist, it is created during the operator installation.
4. Select Approval Strategy as Automatic or Manual.
  If you select Automatic updates, then the Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator without any intervention.
  If you selected Manual updates, then the OLM creates an update request. As a cluster administrator, you must then manually approve that update request to update the Operator to a newer version.
Ensure that the Enable option is selected for the Console plugin.
Click Install.

Verification steps

Verify that the OpenShift Data Foundation Operator shows a green tick indicating successful installation.
