Chapter 5. Deploy standalone Multicloud Object Gateway

Deploying only the Multicloud Object Gateway component with the OpenShift Data Foundation provides the flexibility in deployment and helps to reduce the resource consumption. You can deploy the Multicloud Object Gateway component either using dynamic storage devices or using the local storage devices.

5.1. Deploy standalone Multicloud Object Gateway using dynamic storage devices

Use this section to deploy only the standalone Multicloud Object Gateway component, which involves the following steps:

  • Installing Red Hat OpenShift Data Foundation Operator
  • Creating standalone Multicloud Object Gateway

5.1.1. 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 three worker nodes in the Red Hat OpenShift Container Platform cluster.
  • For additional resource requirements, see the Planning your deployment guide.
Important

  • When you need to override the cluster-wide default node selector for OpenShift Data Foundation, you can use the following command in the 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

  1. Log in to the OpenShift Web Console.
  2. Click Operators → OperatorHub.
  3. Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator.
  4. Click Install.

  5. Set the following options on the Install Operator page:

    1. Update Channel as stable-4.10.
    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 select 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.

    5. Ensure that the Enable option is selected for the Console plugin.
    6. Click Install.

Verification steps

  • After the operator is successfully installed, a pop-up with a message, Web console update is available appears on the user interface. Click Refresh web console from this pop-up for the console changes to reflect.

  • In the Web Console:

    • Navigate to Installed Operators and verify that the OpenShift Data Foundation Operator shows a green tick indicating successful installation.
    • Navigate to Storage and verify if Data Foundation dashboard is available.
