我的docker-compose.yml文件是：

version: '3'
services:
  kafka1:
    image: confluentinc/cp-kafka:7.3.2
    volumes:
      - ./init-scripts/kafka:/docker-entrypoint-initdb.d
    ports:
      - "9092:9092"
    environment:
      KAFKA_ZOOKEEPER_CONNECT: zoo1:2181
      KAFKA_LISTENERS: INTERNAL://:9092,EXTERNAL://:9093
      KAFKA_ADVERTISED_LISTENERS: INTERNAL://kafka1:9092,EXTERNAL://localhost:9093
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INTERNAL:PLAINTEXT,EXTERNAL:PLAINTEXT
      KAFKA_INTER_BROKER_LISTENER_NAME: INTERNAL
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
    depends_on:
      - zoo1
    networks:
      - mynetwork

  zoo1:
    image: confluentinc/cp-zookeeper:7.3.2
    ports:
      - "2181:2181"
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
    networks:
      - mynetwork

  cassandra:
    image: cassandra:latest
    volumes:
      - ./init-scripts/cassandra:/docker-entrypoint-initdb.d
    ports:
      - "9042:9042"

  flask-app:
    build: .
    volumes:
      - .:/app
    ports:
      - "5000:5000"
    depends_on:
      - kafka1
      - cassandra

networks:
  mynetwork:
    driver: bridge

我有一个flask服务器在此运行，但它给了我NoBrokersAvaliable错误。即使我的Kafka和应用程序运行在同一个网络上，它们也无法相互通信。
我有另一个名为esp32_simulator的容器，它有一个像这样的docker-compose文件：

version: '3'
services:

  esp32_simulator:
    build: .
    volumes:
      - ./:/app
    networks:
      - mynetwork

networks:
  mynetwork:
    external:
      name: bitirmetam_mynetwork

但是当我用kafka 1：9092运行这个应用程序时，它也显示NoBrokersAvaliable。我尝试了localhost和一切，但仍然给出错误。
