Knative Apache Kafka installation

A to run Knative with Apache Kafka Source and Channel as default channels.

Installer

Use the 00-installer* scripts for either minikube or kind.

Knative Kafka pack:

The script gets you an installation, that runs:

• Apache Kafka test cluster, using Strimzi
• Knative Serving CORE
• Kourier Ingress
• Knative Eventing (No InMemoryChannel)
• Knative Eventing components for Apache Kafka

The KafkaChannel is used as the default channel, including for the MT Knative Broker.

Run it:

./kn-eventing-kafka.sh

Accessing a service

To extract the host & port for accessing a Knative service via Minikube you can use the following expression:

$(minikube ip):$(kubectl get svc kourier --namespace kourier-system --output 'jsonpath={.spec.ports[?(@.port==80)].nodePort}')

For example:

# Get host:port for acessing a service
ADDR=$(minikube ip):$(kubectl get svc kourier --namespace kourier-system --output 'jsonpath={.spec.ports[?(@.port==80)].nodePort}')

# Create a sample service
kn service create random --image rhuss/random:1.0

# Access the Knative service
curl -sH "Host: random.default.example.com" http://$ADDR | jq .

kn is the official CLI from the Knative project. Get it here!

Have fun!
