How can I explicitly specify NodePort int for Kafka listener / kafka-external-bootstrap ?

[brsolomon-deloitte]

I have e.g.

      - name: external
        port: 9094
        type: nodeport
        tls: false

to enable my-cluster-kafka-external-bootstrap.

This results in the following spec for a kind: Service:

  ports:
    - name: tcp-external
      nodePort: 32426
      port: 9094
      protocol: TCP
      targetPort: 9094

where nodePort is randomly chosen from the available range.

How can I explicitly specify the NodePort port value under a listeners item rather than letting it get its randomly assigned value?

I have checked out kubectl explain kafka.spec.kafka.listeners and am not seeing anything there.

Answering my own question: set kafka.spec.listeners[x]. configuration.bootstrap.nodePort

as described in https://strimzi.io/blog/2019/04/23/accessing-kafka-part-2/#pre-configured-node-port-numbers

spec:
  kafka:
    version: {{ .Values.kafka.version }}
    replicas: {{ .Values.kafka.replicas }}
    listeners:
      - name: plain
        port: 9092
        type: internal
        tls: false
      - name: tls
        port: 9093
        type: internal
        tls: true
      - name: external
        port: 9094
        type: nodeport
        tls: false
        configuration:
          bootstrap:
            nodePort: 31094
