在花了一天时间尝试各种配置选项之后,我还没能让debeziumsqlserver连接器与ksqldb embedded kafka connect一起工作。在ksqldb或debezium网站上似乎都没有关于如何设置这个的明确指导。
有什么文件表明,一个只需要安装相关的Kafka连接插件到一个指定的位置,一切都应该神奇的开箱即用。。。但不幸的是,我没有这样的运气和错误消息,我收到的是没有给我任何反馈工作。
我的docker-compose.yml如下所示,我的.env文件中有debezium_version=1.3和ksqldb_version=0.11.0:

我的上述ksqldb sqlserver服务的dockerfile基本上只获取默认映像,然后将debezium sql server connector插件的内容复制到/usr/share/confluent hub组件,如下所示:
ARG KSQLDB_VERSION
FROM confluentinc/ksqldb-server:${KSQLDB_VERSION}
ARG DEBEZIUM_VERSION=1.3.0.Beta2
ENV PLUGINS_DIR=/usr/share/confluent-hub-components/
ENV CONNECT_PLUGIN_PATH="/usr/share/confluent-hub-components"
USER root
RUN mkdir -p $PLUGINS_DIR && chown -R appuser: $PLUGINS_DIR
USER appuser
RUN cd $PLUGINS_DIR \
&& curl -sO https://repo1.maven.org/maven2/io/debezium/debezium-connector-sqlserver/$DEBEZIUM_VERSION/debezium-connector-sqlserver-$DEBEZIUM_VERSION-plugin.tar.gz \
&& tar -xzf debezium-connector-sqlserver-$DEBEZIUM_VERSION-plugin.tar.gz \
&& rm debezium-connector-sqlserver-$DEBEZIUM_VERSION-plugin.tar.gz
最后,我用于在ksqldb cli中创建连接器的语句如下:
CREATE SOURCE CONNECTOR accounts_reader WITH (
'connector.class' = 'io.debezium.connector.sqlserver.SqlServerConnector',
'database.hostname' = 'host.docker.internal',
'database.port' = '1433',
'database.user' = '******',
'database.password' = ''******',
'database.dbname' = ''******',
'database.server.name' = ''******',
'table.whitelist' = ''******',
'database.history.kafka.bootstrap.servers' = 'kafka:9092',
'database.history.kafka.topic' = ''******',
'tasks.max' = '1'
);
ksqldb cli返回“http error 500 request failed”,在检查ksqldb服务器的docker日志时,我看到以下神秘消息(由于stackoverflow字符限制,我不得不稍微截断它):
[2020-09-17 21:34:15,983] INFO Received: KsqlRequest{ksql='CREATE SOURCE CONNECTOR accounts_reader WITH (

这是一个正在工作的 Docker 。从它可以提炼出如何建立自己的码头形象,如果你想
您可以在这里找到docker compose的完整副本,包括为cdc配置的示例ms sql容器
