Requirements

You will need to have:

• docker compose

How to start?

Start kafka:

docker pull spotify/kafka
docker run -d -p 2181:2181 -p 9092:9092 --env ADVERTISED_HOST=kafka --env ADVERTISED_PORT=9092 --name kafka spotify/kafka

Create topics:

docker exec kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic telegram_in
docker exec kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic telegram_out
docker exec kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic telegram_ids
docker exec kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic facebook_in
docker exec kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic facebook_out

List topics:

docker exec kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-topics.sh --list --zookeeper localhost:2181

Add kafka to /etc/hosts:

127.0.0.1   kafka

Modules

Kafka

All the messaging clients will subscribe/publish to kafka, so we can abstract all the logic from the different platforms and languages.

We initially will have two topics:

• Telegram
• Facebook

Node library for Kafka: https://www.npmjs.com/package/kafka-node

More info: https://github.com/spotify/docker-kafka/pull/64/files

How to test Kafka

Start a producer (in a new terminal window)

docker run -it --rm --link kafka spotify/kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-console-producer.sh --broker-list kafka:9092 --topic test

Start a consumer (in a new terminal window)

docker run -it --rm --link kafka spotify/kafka /opt/kafka_2.11-0.10.1.0/bin/kafka-console-consumer.sh --bootstrap-server kafka:9092 --topic test --from-beginning
