Chapter 3. Installing Data Grid Operator Install Data Grid Operator into a OpenShift namespace to create and manage Data Grid clusters. 3.1. Installing Data Grid Operator on Red Hat OpenShift Create subscriptions to Data Grid Operator on OpenShift so you can install different Data Grid versions and receive automatic updates. Automatic updates apply to Data Grid Operator first and then for each Data Grid node. Data Grid Operator updates clusters one node at a time, gracefully shutting down each node and then bringing it back online with the updated version before going on to the node. Prerequisites Access to OperatorHub running on OpenShift. Some OpenShift environments, such as OpenShift Container Platform, can require administrator credentials. Have an OpenShift project for Data Grid Operator if you plan to install it into a specific namespace. Procedure Log in to the OpenShift Web Console. Navigate to OperatorHub . Find and select Data Grid Operator. Select Install and continue to Create Operator Subscription . Specify options for your subscription. Installation Mode You can install Data Grid Operator into a Specific namespace or All namespaces. Update Channel Get updates for Data Grid Operator 8.4.x. Approval Strategies Automatically install updates from the 8.4.x channel or require approval before installation. Select Subscribe to install Data Grid Operator. Navigate to Installed Operators to verify the Data Grid Operator installation. 3.2. Installing Data Grid Operator with the native CLI plugin Install Data Grid Operator with the native Data Grid CLI plugin, kubectl-infinispan . Prerequisites Have kubectl-infinispan on your PATH . Procedure Run the oc infinispan install command to create Data Grid Operator subscriptions, for example: Verify the installation. Tip Use oc infinispan install --help for command options and descriptions. 3.3. Installing Data Grid Operator with an OpenShift client You can use the oc client to create Data Grid Operator subscriptions as an alternative to installing through the OperatorHub or with the native Data Grid CLI. Prerequisites Have an oc client. Procedure Set up projects. Create a project for Data Grid Operator. If you want Data Grid Operator to control a specific Data Grid cluster only, create a project for that cluster. 1 Creates a project into which you install Data Grid Operator. 2 Optionally creates a project for a specific Data Grid cluster if you do not want Data Grid Operator to watch all projects. Create an OperatorGroup resource. Control all Data Grid clusters Control a specific Data Grid cluster Create a subscription for Data Grid Operator. Note If you want to manually approve updates from the 8.4.x channel, change the value of the spec.installPlanApproval field to Manual . Verify the installation.
