In this tutorial, you’ll deploy an instance of Management Center using Operator.

For more information about Management Center, see https://docs.hazelcast.com/management-center/latest/getting-started/overview.

Prerequisites

  • A Kubernetes or OpenShift cluster.

  • The kubectl or oc command line tools, configured to communicate with your cluster.

  • Operator installed and running.

Deploy Management Center

  1. Create a Kubernetes secret to hold your license key:

    For Kubernetes
    kubectl create secret generic hazelcast-license-key --from-literal=license-key=<YOUR_LICENSE_KEY>
    For Openshift
    oc create secret generic hazelcast-license-key --from-literal=license-key=<YOUR_LICENSE_KEY>

  2. Create the ManagementCenter custom resource file and name it management-center.yaml:

    apiVersion: hazelcast.com/v1alpha1
kind: ManagementCenter
metadata:
  name: managementcenter-sample
spec:
  repository: 'hazelcast/management-center'
  version: '5.9.0'
  licenseKeySecretName: hazelcast-license-key
  externalConnectivity:
    type: LoadBalancer
  hazelcastClusters:
  - address: hazelcast-sample
    name: dev

  3. Apply the custom resource file to start Management Center:

    For Kubernetes
    kubectl apply -f management-center.yaml
    For Openshift
    oc apply -f management-center.yaml

  4. After a moment, you can verify that Management Center is up and running by checking the Management Center logs:

    For Kubernetes
    kubectl logs pod/managementcenter-sample-0
    For Openshift
    oc logs pod/managementcenter-sample-0

2021-08-26 15:21:07,234 [ INFO] [main] [c.h.w.Launcher]: Hazelcast Management Center successfully started at http://localhost:8080/

  1. To access the Management Center dashboard, navigate to http://<management-center-ip-address>:8080 in a browser.

  • Kubernetes

  • Openshift

MANCENTER_IP=$( kubectl get service managementcenter-sample -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
MANCENTER_IP=$( oc get service managementcenter-sample -o jsonpath='{.status.loadBalancer.ingress[0].ip}')

Or if the external IP address of the service is a hostname:

  • Kubernetes

  • Openshift

MANCENTER_IP=$( kubectl get service managementcenter-sample -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
MANCENTER_IP=$( oc get service managementcenter-sample -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')

Next steps

Configure external access to Management Center.
