Expose services

• Pulsar Proxy
• StreamNative Console
• Grafana

​

Access types

• ClusterIP exposes services through the internal IP of the cluster. When selecting this type of service, you can only access it within the cluster by the following methods:
  • ClusterIP + ServicePort
  • Service domain name (${serviceName}.${namespace}) + ServicePort
• LoadBalancer: clients connect to Pulsar proxies, Grafana, StreamNative Console using the Kubernetes provider’s load balancer.
• NodePort: If there is no LoadBalancer, you can choose to expose the service through NodePort. NodePort exposes services through the node’s IP address and static port. You can access a NodePort service from outside of the cluster by requesting NodeIP + NodePort

kubectl get services pulsar-broker -n snpe
NAME                         TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                       AGE
pulsar-broker           ClusterIP      None             <none>        8080:31062/TCP,6650:32198/TCP             2m22s

Access Pulsar cluster using load balancer

1. Set the following in the Pulsar configuration YAML file.
   # Ingresses for exposing Pulsar services
   ingress:
   # Ingresses for exposing pulsar service publicly
   proxy:
      enabled: true
      type:
      tls:
      # If you enable proxy tls, you should enable this too.
      enabled: true
      annotations:
      # If you use aws lb, recommend to add this
      service.beta.kubernetes.io/aws-load-balancer-type: nlb
   
2. Apply the new configuration.
   helm upgrade -f /path/to/your/file.yaml <release_name> streamnative/sn-platform -n <k8s_namespace>
   
3. Get the external IP address or the URL.
   kubectl get svc/<release_name>-sn-platform-proxy-ingress -n <k8s_namespace>
   
   Then you can access the Pulsar cluster through the proxy-ingress HOST/IP address. The relative port should be 8080/6650 for non-TLS access and 443/6651 for TLS access.

​

Access StreamNative Console and Grafana using load balancer

1. Set the following in the Pulsar configuration YAML file.
   # Ingresses for exposing monitoring/management services publicly
   controller:
     enabled: true
     annotations:
     # If you use aws lb, recommend to add this
     service.beta.kubernetes.io/aws-load-balancer-type: nlb
   control_center:
     enabled: true
     # Set external domain of the load balancer of ingress controller
     # external_domain:
   
2. Apply the new configuration.
   helm upgrade -f /path/to/your/file.yaml <release_name> streamnative/sn-platform -n <k8s_namespace>
   
3. Get the external IP address or the URL.
   kubectl get svc/<release_name>-sn-platform-nginx-ingress-controller -n <k8s_namespace>
   
   You can access StreamNative Console and Grafana through nginx-ingress-controller HOST/IP address. The relative port is 80.
   • StreamNative Console URL: http://[nginx-ingress-HOST]/
   • Grafana URL: http://[nginx-ingress-HOST]/grafana
