Question

我在Kubernetes集群（带有Kafka集群，v2.4.0，已经与Strimzi一起部署）上部署了ksqlDB服务器，具有以下部署文件：

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

当我运行ksql时，ksql-cli开始运行，但是我得到Couldn't connect to the KSQL server: KSQL is not yet ready to serve requests和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（使用Kafka集群v2.3.0）上部署了先前的配置，并且一切正常（我可以创建流，连接器ecc）。 ksql-server v5.1.2的先前部署是否可能产生冲突？在部署kubectl之前，我用ksqlDB-server删除了此窗格。预先谢谢你。

无法连接到KSQL服务器：KSQL尚未准备好处理请求
