5장. Configuring Data Grid clusters

Procedure

1. Add Data Grid configuration to a infinispan-config.[xml|yaml|json] key in the data field of your ConfigMap.

   XML

   apiVersion: v1
   kind: ConfigMap
   metadata:
      name: cluster-config
      namespace: rhdg-namespace
   data:
      infinispan-config.xml: >
        <infinispan>
          <!-- Custom configuration goes here. -->
        </infinispan>

   YAML

   apiVersion: v1
   kind: ConfigMap
   metadata:
      name: cluster-config
      namespace: rhdg-namespace
   data:
      infinispan-config.yaml: >
        infinispan:
          # Custom configuration goes here.

   JSON

   apiVersion: v1
   kind: ConfigMap
   metadata:
      name: cluster-config
      namespace: rhdg-namespace
   data:
      infinispan-config.json: >
        {
          "infinispan": {
          }
        }

2. Create the ConfigMap from your YAML file.

   oc apply -f cluster-config.yaml

3. Specify the name of the ConfigMap with the spec.configMapName field in your Infinispan CR and then apply the changes.

   spec:
     configMapName: "cluster-config"
