How to use the Kafka project?
I'm relatively new to Kafka and I want to publish and consume events to the Kafka running in a kafka zookeeper railway project from external code.
How should I do this? Also how do I get the api key need to gett logs from kafka to graphana?

I when I try to hit the domain for the service with a port number I get these errors
{"level":"ERROR","timestamp":"2023-08-23T15:23:18.425Z","logger":"kafkajs","message":"[BrokerPool] Failed to connect to seed broker, trying another broker from the list: Connection timeout","retryCount":2,"retryTime":1150}
am I doing something wrong? is my broker not "kafka-production.up.railway.app:29092"
How do I set this up so that It can get external messages?
Looking it up it seems Like I need to play around with the env variables

You need to set advertised.listeners (or KAFKA_ADVERTISED_LISTENERS if you’re using Docker images) to the external address (host/IP) so that clients can correctly connect to it. Otherwise, they’ll try to connect to the internal host address—and if that’s…
but when I add something like EXTERNAL:kafka-production.up.railway.app:29092 kafka crashes bc it can't bind to that

Oh wow I didn’t know they did kafka too!
