Kafka Helm chart

The kafka helm chart is not maintained by CORD, but it is available online at: https://github.com/kubernetes/charts/tree/master/incubator/kafka

To install kafka you can use:

helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
helm install -f examples/kafka-single.yaml --version 0.8.8 -n cord-kafka incubator/kafka
helm install -f examples/kafka-single.yaml --version 0.8.8 -n voltha-kafka incubator/kafka

Viewing events with kafkacat

As a debugging tool you can deploy a container containing kafkacat and use that to listen for events:

helm install -n kafkacat xos-tools/kafkacat/

Once the container is up and running you can exec into the pod and use various commands. For a complete reference, please refer to the kafkacat guide

A few examples:

• List available topics:

  kafkacat -L -b <kafka-service>
  

• Listen for events on a particular topic:

  kafkacat -C -b <kafka-service> -t <kafka-topic>
  

• Some common topics to listen for on cord-kafka and voltha-kafka:

  kafkacat -b cord-kafka -t onu.events
  kafkacat -b cord-kafka -t authentication.events
  kafkacat -b cord-kafka -t dhcp.events
  kafkacat -b voltha-kafka -t voltha.events
