Question

我正在尝试使用curl命令为kafka创建JDBC连接器。请帮助我纠正此命令。

curl -X POST -H "Content-Type: application/json"  --data "{ \"name\": 
\"ib_connector\",\"config\": { \"connector.class\": \"io.confluent.connect.jdbc.JdbcSourceConnector\", \"tasks.max\": 1,
\"connection.url\": \"jdbc:interbase://ip:3050;Database=TEST2;user=SYSDBA;password=masterkey\",\"mode\": \"timestamp+incrementing\", \"incrementing.column.name\": \"id\",\"timestamp.column.name\": \"modified\", \"topic.prefix\": \"test-interbase-\", \"poll.interval.ms\": 1000 } }"
http://localhost:8083/connectors

在命令提示符下显示以下错误

curl: (52) Empty reply from server

我正在这样运行docker-compose.yml文件

kafka正在运行，并且我已经使用命令docker-compose up -d来运行它，并且得到了成功消息。我在Windows上运行它。下面是容器的状态。

当我运行docker-compose up -d时，它显示为Kafka_manager正在启动。但是，一旦我检查状态，它就会显示出口255。这是否会影响将配置保存到端口8083。

可能是什么原因。 Kafka-connect处于活动状态并且正在端口8083中运行。请帮助

Answer 1

kafka在9092上运行，而connect worker在8083上运行。

您要在8083上发布配置，因此请确保您的工作人员已启动并正在运行。
