Red Hat Summit2장. Deploy OpenShift Data Foundation using dynamic storage devices
You can deploy OpenShift Data Foundation on OpenShift Container Platform using dynamic storage devices provided by Amazon Web Services (AWS) EBS (type, gp2-csi or gp3-csi) that provides you with the option to create internal cluster resources. This results in the internal provisioning of the base services, which helps to make additional storage classes available to applications.
Also, it is possible to deploy only the Multicloud Object Gateway (MCG) component with OpenShift Data Foundation. For more information, see Deploy standalone Multicloud Object Gateway.
Only internal OpenShift Data Foundation clusters are supported on AWS. See Planning your deployment for more information about deployment requirements.
Also, ensure that you have addressed the requirements in Preparing to deploy OpenShift Data Foundation chapter before proceeding with the below steps for deploying using dynamic storage devices:
2.1. 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-adminand operator installation permissions. - You must have at least three worker or infrastructure nodes in the Red Hat OpenShift Container Platform cluster.
- For additional resource requirements, see the Planning your deployment guide.
When you need to override the cluster-wide default node selector for OpenShift Data Foundation, you can use the following command to specify a blank node selector for the
openshift-storagenamespace (createopenshift-storagenamespace in this case):$ oc annotate namespace openshift-storage openshift.io/node-selector=-
Taint a node as
infrato ensure only Red Hat OpenShift Data Foundation resources are scheduled on that node. This helps you save on subscription costs. For more information, see the How to use dedicated worker nodes for Red Hat OpenShift Data Foundation section in the Managing and Allocating Storage Resources guide.
Procedure
- Log in to the OpenShift Web Console.
-
Click Operators
OperatorHub. -
Scroll or type
OpenShift Data Foundationinto the Filter by keyword box to find the OpenShift Data Foundation Operator. - Click Install.
Set the following options on the Install Operator page:
- Update Channel as stable-4.14.
- Installation Mode as A specific namespace on the cluster.
-
Installed Namespace as Operator recommended namespace openshift-storage. If Namespace
openshift-storagedoes not exist, it is created during the operator installation. 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.
- Ensure that the Enable option is selected for the Console plugin.
- Click Install.
Verification steps
-
After the operator is successfully installed, a pop-up with a message,
Web console update is availableappears 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 the Data Foundation dashboard is available.
