即使在配置了 confluent kafka docker-compose 的机器重新启动后，如何保持所有配置的设置？
How to keep all the settings configured even after restarting a machine with confluent kafka docker-compose configured?
这是我用于 kafka 和 ksqldb 设置的 docker-compose 文件，

我添加了 mysql 作为我的源连接器和 elasticsearch 作为接收器连接器，我已经使用 ksqldb 来处理所有 t运行sformation 的东西，这是我在 ksqldb 中 运行 的命令.
docker-compose up --build成功后，我运行这个命令去ksqldb，
docker exec -it ksqldb-cli ksql http://ksqldb-server:8088
进入 ksqldb 后，我 运行 以下代码的顺序与此处相同
CREATE SOURCE CONNECTOR `source_mysql_connector` WITH(<CONFIG>);
SET 'auto.offset.reset' = 'earliest';
CREATE STREAM candidate_input WITH (KAFKA_TOPIC='test.AF.candidate', KEY_FORMAT='JSON', VALUE_FORMAT='AVRO');
CREATE STREAM candidate_target WITH (KAFKA_TOPIC='test.AF.candidate.target', KEY_FORMAT='JSON', VALUE_FORMAT='AVRO') FROM candidate_input;
SET 'auto.offset.reset' = 'earliest';
# sink connector
CREATE SINK CONNECTOR `sink_elasticsearch` WITH (<CONFIG>);
假设我已经在我的机器上配置了所有这些并且一切正常。我可以看到数据正在从我的源 mysql 传输 运行 到 elasticsearch 接收器。
现在的问题是，如果我关闭我的电脑，当我重新打开它时。所有容器将被关闭。
所以我做到了，docker-准备启动所有服务。
现在，当我去控制中心检查所有创建的主题和 ksqldb 流时，所有连接器都被删除了。
有什么方法可以让我在每次拆机后都保持完好无损。
Docker 卷是临时的，因此这是预期的行为。
你需要mount host volumes for at least the Kafka and Zookeeper containers
例如
# zookeeper
volumes:
- /some/host/path/zk:/var/lib/zookeeper/data
# broker
volumes:
- /some/host/path/kafka:/var/lib/kafka/data
