使用docker使用fast data dev将Kafka主题连接到elasticsearch

我将使用和elasticsearch latest，kibana latest将数据从kafka发送到elasticsearch。但我得到了以下错误：

以下是elasticsearch的接收器连接器配置

connector.class=io.confluent.connect.elasticsearch.ElasticsearchSinkConnector
type.name=kafka-connect
tasks.max=1
topics=elastic
topic.index.map="elastic:index1"
topic.key.ignore=true
value.converter=org.apache.kafka.connect.json.JsonConverter
connection.url=http://127.0.0.1:9200
key.converter=org.apache.kafka.connect.json.JsonConverter
topic.schema.ignore=true

我想链接同一网络中的所有容器，这样我就不必处理连接问题，但似乎我遗漏了一些东西。 任务未运行。

任何建议都会很有帮助。

使用网络后，它将不再是本地主机。您需要将服务名称用作

connection.url

。你能试试

connection.url吗=http://elasticsearch:9200

也许没有

http

谢谢@Mustafa Guler的回答，它起作用了。请接受回答并结束问题。
