testcontainers-spring-boot: Kafka container can not submit metrics to Confluent

I have Spring Boot based web app with Kafka integration and I use embedded-kafka to spin up Kafka container.

I use typical configuration:

spring.kafka.bootstrap-servers=${embedded.kafka.brokerList}
embedded.kafka.topicsToCreate=tickets

and confluentinc-cp-kafka:5.4.1 docker image

https://hub.docker.com/r/confluentinc/cp-kafka/tags

docker pull confluentinc/cp-kafka:5.4.1

When I run test in Gitlab CI, it fails to spin up Kafka container:

Is it possible to turn off ConfluentSubmitter? Is there any way how to overcome this issue? Different docker image?
