我部署了 ksqlDB kubernetes群集上的服务器（带有kafka群集，v2.4.0，已使用strimzi部署），部署文件如下：

apiVersion: v1
kind: Pod
metadata:
  name: ksqldb-server
  labels:
    app: ksqldb-server
spec:
  containers:
    - name: ksqldb-server
    # get latest version of image
    image: confluentinc/ksqldb-cli:latest
 imagePullPolicy: IfNotPresent
 command: ["/bin/bash"]
 args: ["-c","echo Waiting for Kafka to be ready... && \
                    cub kafka-ready -b my-kafka-brokers:9092 1 20 && \
                    echo Waiting a few seconds for topic creation to finish... && \
                    sleep 2 && \
                    /usr/bin/ksql-server-start /etc/ksqldb/ksql-server.properties"]
 env:
 - name: KSQL_CONFIG_DIR
   value: "/etc/ksqldb"
 - name: KSQL_OPTS
   value: "-Dbootstrap.servers=my-kafka-brokers:9092 -Dksql.streams.auto.offset.reset=earliest"
 - name: KSQL_LOG4J_OPTS
   value: "-Dlog4j.configuration=file:/etc/ksqldb/log4j-rolling.properties"
 ports:
 # containerPort is the port exposed by the container (where ksql server is listening)
 - containerPort: 8088

当我跑的时候 ksql , ksql-cli 开始但我得到 Couldn't connect to the KSQL server: KSQL is not yet ready to serve requests 以及 Server Status: <unknown> . 我无法成功执行任何语句( LIST TOPICS; CREATE STREAMS ecc）。我在另一个kubernetes集群（kafka cluster v2.3.0）上部署了以前的配置，一切正常（我可以创建流、连接器和ecc）。以前部署的 ksql-server v5.1.2会产生冲突吗？我用删除了这个豆荚 kubectl 之前 ksqlDB-server 部署。先谢谢你。
