kafka连接码头工人与外部服务

Question

我遵循了在本地网络中使用此模式的教程的工作原理，现在，我想尝试将生产者从本地服务更改为外部服务（生产）。

docker-compose.yml

version: '2'
services:
  zookeeper:
    image: debezium/zookeeper:${DEBEZIUM_VERSION}
    ports:
     - 2181:2181
     - 2888:2888
     - 3888:3888
  kafka:
    image: debezium/kafka:${DEBEZIUM_VERSION}
    ports:
     - 9092:9092
    links:
     - zookeeper
    environment:
     - ZOOKEEPER_CONNECT=zookeeper:2181
  mysql:
    image: debezium/example-mysql:${DEBEZIUM_VERSION}
    ports:
     - 3306:3306
    environment:
     - MYSQL_ROOT_PASSWORD=debezium
     - MYSQL_USER=mysqluser
     - MYSQL_PASSWORD=mysqlpw 
  postgres:
    image: debezium/postgres:9.6
    ports:
     - "5432:5432"
    environment:
     - POSTGRES_USER=postgresuser
     - POSTGRES_PASSWORD=postgrespw
     - POSTGRES_DB=inventory
  connect:
    image: debezium/connect-jdbc-es:${DEBEZIUM_VERSION}
    build:
      context: debezium-jdbc-es
    ports:
     - 8083:8083
     - 5005:5005
    links:
     - kafka
     - mysql
     - postgres
    environment:
     - BOOTSTRAP_SERVERS=kafka:9092
     - GROUP_ID=1
     - CONFIG_STORAGE_TOPIC=my_connect_configs
     - OFFSET_STORAGE_TOPIC=my_connect_offsets

那个kafka连接链接mysql ( producer )，那么如何将生产者更改为外部服务？删除mysql，connect中的链接又如何呢？谢谢
