Integrating Hono and Enmasse

I am trying to deploy hono with enmasse. For this, I already installed enmasse and created address spaces and addresses following this repository.

As described in hono-doc on artifacthub. First I created a secret.

my_secret.yaml

apiVersion: v1
kind: Secret
metadata:
  name: mysecret
stringData:
  amqp-credentials.properties: |
    username: hono
    password: HONO

and applied it into the hono-namespace:

kubectl apply -f ./hono/my_secret.yaml -n hono

After that, I created my own values.yaml file to overwrite the hono default values, as described in "Integrating with an existing AMQP Messaging Network".

my_values.yaml

amqpMessagingNetworkExample:
  enabled: false

adapters:
  extraSecretMounts:
  - amqpNetwork:
      secretName: "mysecret"
      mountPath: "/etc/custom"

  amqpMessagingNetworkSpec:
    host: messaging-5355a0a.enmasse-infra
    port: 5672
    credentialsPath: /etc/custom/amqp-credentials.properties

  commandAndControlSpec:
    host: messaging-5355a0a.enmasse-infra
    port: 5672
    credentialsPath: /etc/custom/amqp-credentials.properties

  amqp:
    enabled: false

deviceRegistryExample:
  enabled: true
  type: mongodb
  addExampleData: false

mongodb:
  createInstance: true

grafana:
  enabled: false

prometheus:
  createInstance: false

At least I installed hono with:

helm install -n hono -f ./hono/my_values.yaml c2e eclipse-iot/hono

But unfortunately, I get errors and pods do not run well, In particular I get these errors from all pods, that try to connect to the enmasse-Amqp network:

Mount-Error: Secret file "amqp-credentials.properties" is not getting mounted: The pod's logfiles says "No such a file or directory":

10:47:45.645 [vert.x-eventloop-thread-0] WARN o.e.h.config.ClientConfigProperties - could not load client credentials for [messaging-5355a0a.enmasse-infra:5672, role: Command & Control] from file [/etc/custom/amqp-credentials.properties] java.io.FileNotFoundException: /etc/custom/amqp-credentials.properties (No such file or directory)

Wrong AMQP connection: For some reason, all pods try to connect to enmasse through "amqps" even though I am explicitly saying they should use "amqp" through port number and not providing crt-keys! Am I wrong?

What am I doing wrong here?

Also, that would be great if someone could provide an exemplary "Hono+Enmasse" integration repository.

Thanks

Solution

You cannot specify extra secret mounts at the adapters level. You need to specify the extraSecretMounts property for each adapter individually, e.g. for the HTTP and MQTT adapter:

adapters:
  http:
    extraSecretMounts:
      amqpNetwork:
        secretName: "mysecret"
        mountPath: "/etc/custom"
  mqtt:
    extraSecretMounts:
      amqpNetwork:
        secretName: "mysecret"
        mountPath: "/etc/custom"

Also note that extraSecretMounts value is not an array but an object, i.e. there must not be a - character before the amqpNetwork property.
