Yeah, that won't work. You have to restart Connect process for any plugin to be discovered. You would have to write your own Dockerfile. See https://github.com/confluentinc/cp-docker-images/blob/5.3.1-post/debian/kafka-connect/Dockerfile#L41 for example

Is there a specific reason you need to use host network mode?

Have you tried submitting this ticket to the proper, current schema registry docker repo?

Please refer Readme for correct repo. Your issue is in the base, which is in the kafka images repo https://github.com/confluentinc/cp-docker-images/blob/5.3.3-post/README.md#deprecation-notice

Can these not be added from Java properties?

Better to use either - `docker network create ` and `docker run --network= -e KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181` with zookeeper on same network - Docker Compose ([provided in repo](https://github.com/confluentinc/cp-docker-images/blob/5.3.3-post/examples/kafka-single-node/docker-compose.yml))
