If you want to deploy a Kafka Streams application, then essentially you only need the (fat) jar of your application and a JRE in your container. In other words, it's the same setup you'd use to deploy *any* kind of Java application.
You do not need to containerize "Kafka", which I assume you meant as containerizing "a Kafka cluster or broker". > And after I have the container running, in my container should I run Java -cp ... same as > https://github.com/confluentinc/examples/blob/3. 2.x/kafka-streams/src/main/java/io/confluent/examples/streams/WordCountLambdaExample.java#L55-L62?
