Running

With Docker Compose - Nerdctl Compose

  1. You need to have docker installation locally. With containerd backend, if you want to bring single node Kafka replacement use:
$ nerdctl compose up

If you want to bring Confluent Kafka single node. You can:

$ nerdctl compose -f docker-compose.kafkasn.yml

If you want to bring full blown Confluent Kafka cluster. Use:

$ nerdctl compose -f docker-compose.kafkacluster.yml

Mind that nerdctl command is interchangeable with docker.

With K8S

  1. You need to have K8S installation locally.
$ cd k8s && kubectl apply -f . && kubectl port-forward svc/redpanda 9092:9092
  1. Now you can run the producers in Python.
$ virtualenv venv
$ source venv/bin/activate
$ which pip3 # check that it is pointing to venv
$ pip3 install aiokafka -U
$ python examples/producer.py
  1. Now you can spawn the double agent example (without durability).
$ RUST_LOG="info,rdkafka::client=warn" RUST_BACKTRACE=full cargo run --example double-agent

Environment variables passed above is optional, but suggested for development.
