Configure external access to Management Center

You can expose Management Center outside Kubernetes to remotely manage your Hazelcast deployment.

Management Center supports several options for external access.

Configure external access

Operator supports the following configuration for Management Center external access.

Field Description

Field	Description
`externalConnectivity.type`	Management Center external access methods: `LoadBalancer` (default): On cloud providers that support external load balancers, setting `LoadBalancer` provisions a load balancer for your Management Center. `NodePort`: If you set `NodePort`, the Kubernetes control plane allocates a port from a reserved range (default: 30000-32767). Each node proxies that port (the same port number on every node) into your Kubernetes service. `ClusterIP`: Assigns an IP address from a pool of internal IP addresses that your Kubernetes cluster has reserved for that purpose.
`externalConnectivity.ingress`	Ingress exposes HTTP and HTTPS routes from outside the Kubernetes cluster to Management Center. Traffic routing is controlled by rules defined on the Ingress resource.
`externalConnectivity.route`	An OpenShift Container Platform Route exposes a service at a host name so that external clients can reach it by name.

Management Center external access methods:

LoadBalancer (default): On cloud providers that support external load balancers, setting LoadBalancer provisions a load balancer for your Management Center.
NodePort: If you set NodePort, the Kubernetes control plane allocates a port from a reserved range (default: 30000-32767). Each node proxies that port (the same port number on every node) into your Kubernetes service.
ClusterIP: Assigns an IP address from a pool of internal IP addresses that your Kubernetes cluster has reserved for that purpose.

externalConnectivity.ingress

Ingress exposes HTTP and HTTPS routes from outside the Kubernetes cluster to Management Center. Traffic routing is controlled by rules defined on the Ingress resource.

externalConnectivity.route

An OpenShift Container Platform Route exposes a service at a host name so that external clients can reach it by name.

Example Management Center load balancer configuration

The following example exposes Management Center using a dedicated load balancer.

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

Example Management Center ingress configuration

The following example exposes Management Center using Ingress.

apiVersion: hazelcast.com/v1alpha1
kind: ManagementCenter
metadata:
  name: managementcenter
spec:
  repository: "hazelcast/management-center"
  licenseKeySecretName: hazelcast-license-key
  externalConnectivity:
    type: ClusterIP
    ingress:
      hostname: "example.hostname"
      ingressClassName: nginx
      path: "/mancenter"
      annotations:
        nginx.ingress.kubernetes.io/enable-opentelemetry: "true"
  hazelcastClusters:
    - address: hazelcast
      name: dev

Example Management Center route configuration

kind: ManagementCenter
metadata:
  name: managementcenter
spec:
  repository: "hazelcast/management-center"
  licenseKeySecretName: hazelcast-license-key
