红帽全球峰会第 3 章 Deploy standalone Multicloud Object Gateway
Deploying only the Multicloud Object Gateway component with OpenShift Data Foundation provides the flexibility in deployment and helps to reduce the resource consumption. 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
The Multicloud Object Gateway only has a single copy of the database (NooBaa DB). This means if NooBaa DB PVC gets corrupted and we are unable to recover it, can result in total data loss of applicative data residing on the Multicloud Object Gateway. Because of this, Red Hat recommends taking a backup of NooBaa DB PVC regularly. If NooBaa DB fails and cannot be recovered, then you can revert to the latest backed-up version. For instructions on backing up your NooBaa DB, follow the steps in this knowledgabase article.
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. - 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-4.15.
- 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.
