Hazelcast Management Center for OpenShift

Hazelcast Management Center enables you to monitor and manage your cluster members running Hazelcast IMDG. In addition to monitoring the overall state of your clusters, you can also analyze and browse your data structures in detail, update map configurations and take thread dumps from members. You can run scripts (JavaScript, Groovy, etc.) and commands on your members with its scripting and console modules.

You can check Hazelcast IMDG Documentation and Management Center Documentation for more information.

Note: This repository contains Dockerfile only for the RHEL image available at Red Hat Container Catalog: registry.connect.redhat.com/hazelcast/management-center-4-rhel8. For any other OpenShift use cases, please use the standard Docker image: hazelcast/management-center.

Quick Start

You can launch Hazelcast Management Center by running the following command (please check available versions for $MC_VERSION on Docker Store):

$ oc new-app hazelcast/management-center:${MC_VERSION}

To access Management Center from outside of the container, you need to expose it using oc expose svc/management-center, then its accessible via the exposed route + /hazelcast-mancenter (which you can check by oc get route).

Using Persistent Volume for Management Center Data Directory

Management Center uses the file system to store persistent data. However, that is by default a temporary storage and destroyed in case the container restarts. If you want to store Management Center data externally, you need to create a Persistent Volume Claim and mount it into Management Center.

$ oc volume deploymentconfigs/management-center --remove --confirm
$ oc volume deploymentconfigs/management-center --add --claim-size 2G --mount-path /data --name mc-data

You can read more about OpenShift Persistent Volumes here.

Management Center License

To provide a license key the system property hazelcast.mc.license can be used (requires version >= 3.9.3):

$ oc set env deploymentconfigs/management-center JAVA_OPTS='-Dhazelcast.mc.license=<key>'
