Data Grid Operator, available from the Operator Hub on Red Hat OpenShift, simplifies the process of creating and managing Data Grid clusters on OpenShift.

Data Grid Operator watches for the Infinispan Custom Resources (CR) that you use to instantiate and configure Data Grid clusters and manage OpenShift resources, such as StatefulSets and Services. In this way, the Infinispan CR is your primary interface to Data Grid on OpenShift.

If you’re new to OpenShift, try some quick exercises in the Interactive Learning Portal.

Install Data Grid Operator into OpenShift projects from the Operator Hub.

You can create Data Grid clusters from:

Data Grid Operator creates a minimal Infinispan CR with new cluster instances:

apiVersion: infinispan.org/v1 1
kind: Infinispan 2
metadata:
  name: example-infinispan 3
  namespace: rhdg-helloworld 4
spec:
  replicas: 2 5

Applying the minimal Infinispan CR creates a cluster of two Cache service nodes that provide a volatile, low-latency data store with a default configuration.

Data Grid Operator lets you configure Data Grid cluster properties such as:

When you instantiate a Data Grid cluster instance, Data Grid Operator brings the nodes up. When the nodes are running, navigate back to the Infinispan tab to access the Infinispan CR and view available resources like authentication secrets and services.
