How was this tested?

A local Kubernetes cluster was created using kind. The urunc runtime class, Kourier ingress, and the patched Knative Serving components were deployed on the cluster.

  1. Container-based Knative service (hellocontainerc)

Applied the example service:

kubectl apply -f https://raw.githubusercontent.com/nubificus/c-httpreply/refs/heads/main/service.yaml

Verification:

curl -H "Host: hellocontainerc.default.127.0.0.1.nip.io" \
  http://<INGRESS_IP>:80

Result:

  • Knative service reached READY=True.
  • The service correctly returned Hello, World!.
  1. Unikraft-based Knative service (hellounikernelfc)

Applied the updated service manifest:

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: hellounikernelfc
spec:
  template:
    spec:
      runtimeClassName: urunc
      containers:
        - name: user-container
          image: harbor.nbfc.io/nubificus/knative-example-functions/httpreply-fc:latest
          imagePullPolicy: Always
          env:
            - name: RUNTIMECLASS
              value: "urunc"

Verification:

curl -v -H "Host: hellounikernelfc.default.127.0.0.1.nip.io" \
  http://<INGRESS_IP>:80

Result:

  • The pod successfully booted the Helene 0.18.0 unikernel VM.
  • The queue-proxy sidecar successfully completed readiness checks.
  • The Knative service reached READY=True.
  • Requests were successfully served by the Unikraft guest.

Example response:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Unikraft Boot Time Demo</title>
</head>
<body>
  <h1>Hello from Unikraft!</h1>
  ...
</body>
</html>
