I'm using confluentinc/cp-server-connect (https://hub.docker.com/r/confluentinc/cp-server-connect) with elasticsearch sink connector (https://www.confluent.io/hub/confluentinc/kafka-connect-elasticsearch) i added trough dockerfile and rebuilding the image and it works just fine. I'm configuring the connector using http requests like it's done in this tutorial https://www.confluent.io/blog/kafka-elasticsearch-connector-tutorial/. My problem is that I couldn't find a way to keep the connector configuration i set during removing and stopping again the docker container with this image.

I couldn't find any mentions of keeping configuration in docker image's documentation on docker hub or by googling it. I also tried manually searching in the image for where this configuration may be stored but i had no luck. Where should I point with docker volume to save this configuration, or maybe the configuration is kept somewhere else like in a specific topic in kafka?

CodePudding user response：

Yes, the configurations are kept on Kafka topic. The Connect container doesn't store them.

Therefore, don't restart the Kafka (or Zookeeper) container(s), and your configs will be maintained.
