Azure AKS - LoadBalancer instead of ClusterIP

[klemen-df]

I'm trying to use the operator to configure a single node EMQX 5. I use terraform so don't mind the exact syntax.

I install the operator with helm and create a single instance EMQX 5 👍

    "spec" = {
      "image" = "emqx/emqx:5.0.17"
      "coreTemplate" = {
        "spec" = {
          "replicas" = 1
        }
      }
      "replicantTemplate" = {
        "spec" = {
          "replicas" = 0
        }
      }

I configure the bootstrapConfig to include listening on the tls/8883 port :

        listeners.ssl.mqtts {
          bind = "0.0.0.0:8883"
          max_connections = 1024000
          ssl_options {
            keyfile = "/etc/certs/key.pem"
            certfile = "/etc/certs/cert.pem"
            versions = ["tlsv1.3", "tlsv1.2"]
          }
        }  

A service of type ClusterIP is created, it listens on 8883/TCP and 1883/TCP.

Is there a way to tell the operator that this should be of LoadBalancer type?

You can set .spec.listenersServiceTemplate.spec.type = LoadBalancer, and if need add some annotations from Azure, you can set .spec.listenersServiceTemplate.metadata.annotations

Many thanks, this works.

Would it be also possible to setup a ClusterIP for 1883 and LoadBalancer for 8883 or do they have to be of the same type?

[Rory-Z]

It must the same type. but you can create a new service resource by yourself, and use .spec.selector to match EMQX pod

[klemen-df]

Should we just match :
apps.emqx.io/db-role=core
apps.emqx.io/instance=emqx
apps.emqx.io/managed-by=emqx-operator
?

In EMQX 5, there are two types of nodes: core nodes and replicant nodes. We recommend accessing the dashboard (port 18083) through a core node and connecting MQTT clients to a replicant node (port 1883). Therefore, our CR provides dashboardServiceTemplate and listenerServiceTemplate, which you can set according to your needs.
