我编写了一个基于java的微服务，它将（producer）写入kafka队列。当我测试我的微服务时，它正在将数据正确地写入Kafka。
这些都是我的设置。

"bootstrap.servers":"localhost:9092",
        "TOPIC":"my.data",
        "PARTITION":"0",
        "key.deserializer":"org.apache.kafka.common.serialization.StringDeserializer",
        "value.deserializer":"org.apache.kafka.common.serialization.StringDeserializer",
        "enable.auto.commit":"false"

当我在docker上安装microservice时，我将设置更改为

"bootstrap.servers":"host.docker.internal:9092",
        "TOPIC":"my.data",
        "PARTITION":"0",
        "key.deserializer":"org.apache.kafka.common.serialization.StringDeserializer",
        "value.deserializer":"org.apache.kafka.common.serialization.StringDeserializer",
        "enable.auto.commit":"false"

microservice失败，出现以下错误。

2020-11-19 18:41:14,958 WARN [org.apa.kaf.cli.NetworkClient] (kafka-producer-network-thread | producer-1) [Producer clientId=producer-1] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available.

我遗漏了什么吗？任何帮助都将不胜感激。
