Thanks, @eddumelendez. A few notes and things for us to think about prior to merging this (plenty of time as this is just too late for 3.3 unfortunately):

• Should we rename our existing KafkaContainerConnectionDetailsFactory to ConfluentKafkaContainerConnectionDetailsFactory, and similar for the existing KafkaContainerConnectionDetails?
• Should we rename org.springframework.boot.testsupport.testcontainers.DockerImageNames.kafka()?

In addition to these, we'll also need to do something about the docs. When we upgrade to Testcontainers 1.19.8, "Containers of type KafkaContainer" will become ambiguous as there will be two types named KafkaContainer. I've opened #40699 for that. We'll then need to make some further changes here so that it's clear that both KafkaContainer types are supported.

Hi @wilkinsona,

Should we rename our existing KafkaContainerConnectionDetailsFactory to ConfluentKafkaContainerConnectionDetailsFactory, and similar for the existing KafkaContainerConnectionDetails?

We are planning to deprecate the existing one under org.testcontainers.container.KafkaContainer and provide a Confluent module with org.testcontainers.confluent.KafkaContainer. So, with those changes I think we can add a new ConfluentKafkaContainerConnectionDetailsFactory and ConfluentKafkaContainerConnectionDetails when available and deprecate existing Kafka* implementations in SB.

Should we rename org.springframework.boot.testsupport.testcontainers.DockerImageNames.kafka()?

Yes.

Thanks very much, @eddumelendez.
