Chapter 1. Installing Data Grid Operator

download PDF

Install Data Grid Operator into a OpenShift namespace to create and manage Data Grid clusters.

1.1. 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 next 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

  1. Log in to the OpenShift Web Console.
  2. Navigate to OperatorHub.
  3. Find and select Data Grid Operator.
  4. Select Install and continue to Create Operator Subscription.
  5. 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 8.1.x.
    Approval Strategies
    Automatically install updates from the 8.1.x channel or require approval before installation.
  6. Select Subscribe to install Data Grid Operator.
  7. Navigate to Installed Operators to verify the Data Grid Operator installation.

1.2. Installing Data Grid Operator from the Command Line

As an alternative to installing Data Grid Operator through the OperatorHub on OpenShift, use the oc client to create subscriptions.

Prerequisites

  • Have an oc client.

Procedure

  1. Set up projects.

    1. Create a project for Data Grid Operator.
    2. If you want Data Grid Operator to control a specific Data Grid cluster only, create a project for that cluster.

      $ oc new-project ${INSTALL_NAMESPACE} 1
      $ oc new-project ${WATCH_NAMESPACE} 2
      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.
  2. Create an OperatorGroup resource.

    Control all Data Grid clusters

    $ oc apply -f - << EOF
    apiVersion: operators.coreos.com/v1
    kind: OperatorGroup
    metadata:
     name: datagrid
     namespace: ${INSTALL_NAMESPACE}
    EOF

    Control a specific Data Grid cluster

    $ oc apply -f - << EOF
    apiVersion: operators.coreos.com/v1
    kind: OperatorGroup
    metadata:
     name: datagrid
     namespace: ${INSTALL_NAMESPACE}
    spec:
     targetNamespaces:
     - ${WATCH_NAMESPACE}
    EOF

  3. Create a subscription for Data Grid Operator.

    $ oc apply -f - << EOF
    apiVersion: operators.coreos.com/v1alpha1
    kind: Subscription
    metadata:
     name: datagrid-operator
     namespace: ${INSTALL_NAMESPACE}
    spec:
     channel: 8.1.x
     installPlanApproval: Automatic 1
     name: datagrid
     source: redhat-operators
     sourceNamespace: openshift-marketplace
    EOF
    1
    Specify Manual if you want to manually approve updates from the 8.1.x channel.
  4. Verify the installation.

    $ oc get pods -n ${INSTALL_NAMESPACE}
    NAME                                   READY   STATUS
    infinispan-operator-<id>               1/1     Running
