我用follow yaml设置了一个Strimzi集群。

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: kafka
spec:
  kafka:
    replicas: 3
    listeners:
      - name: plain
        port: 9092
        type: internal
        tls: false
      - name: tls
        port: 9093
        type: internal
        tls: true
        authentication:
          type: tls
      - name: external
        port: 9094
        type: route
        authentication:
          type: scram-sha-512
        tls: true

豆荚运行良好，我使用SCRAM-512创建了一个KafkaUserCR，如下所示-

apiVersion: kafka.strimzi.io/v1beta1
kind: KafkaUser
metadata:
  name: scram-user
  labels:
    strimzi.io/cluster: kafka
spec:
  authentication:
    type: scram-sha-512

我已经正确地从秘密中提取了SCRAM密码，并从集群证书秘密中获取了ca. crt文件。我正在尝试遵循这个示例中的Go Sarama代码-https://github.com/Shopify/sarama/blob/master/examples/sasl_scram_client/main.go

我也从OpenShift路由中正确获取了引导服务器地址，但我似乎无法连接。

go run sarama.go scram_client.go -brokers bootstrap-address:443  -username scram-user -passwd esoy2WksWRBp -topic test-topic -algorithm sha512 -tls true -ca /path/ca.crt

我已经尝试了上述命令的一些变体，添加了 -certificate 或 -key 标志，但似乎都不起作用。我的侦听器设置有误吗？

编辑-忘记包括和提到它，但这是我从Go Sarama代码中得到的错误。

[Sarama] 2021/08/18 09:22:36 Failed to send SASL handshake kafka-broker:443: x509: certificate signed by unknown authority
[Sarama] 2021/08/18 09:22:36 Closed connection to broker kafka-broker:443

[Producer] 2021/08/18 09:22:36 failed to create producer:  kafka: client has run out of available brokers to talk to (Is your cluster reachable?)
exit status 1

因此，这看起来是一个证书问题，但我似乎遵循了正确的说明来获得证书。我的Kafka经纪人刚刚命名为Kafka，所以这个秘密刚刚命名为Kafka-cluster-ca-cert。＜code＞ca.crt＜/code＞文件是我提供给Sarama代码的路径。

oc get secret kafka-cluster-ca-cert -o jsonpath='{.data.ca\.crt}' | base64 -d > ca.crt

如果重要的话，描述一下秘密——
