Can not deploy whoami in kubernetes/traefik

Traefik Traefik v2
,

I have traefik running tuning in my kubernetes cluster at a namespace labeled purelb:

$ kubectl get pods -n purelb
NAME                         READY   STATUS    RESTARTS     AGE

$ kubectl get services -n purelb

I am trying to deploy the whoami example using:

$ cat deploy_whoami.yaml
# whoami.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: whoami
  namespace: purelb
spec:
  replicas: 2
  selector:
    matchLabels:
      app: whoami
  template:
    metadata:
      labels:
        app: whoami
    spec:
      containers:
        - name: whoami
          image: traefik/whoami
          ports:
            - containerPort: 80
---
# whoami-service.yaml
apiVersion: v1
kind: Service
metadata:
  name: whoami
  namespace: purelb
spec:
  ports:
    - port: 80
  selector:
    app: whoami


---
# whoami-ingressroute.yaml
apiVersion: traefik.io/v1alpha1
kind: IngressRoute
metadata:
  name: whoami
  namespace: purelb
spec:
  entryPoints:
    - websecure
  routes:
    - match: Host(`kbapache.cn.lan`)
      kind: Rule
      services:
        - name: whoami
          port: 80
  tls:
    secretName: purelb-selfsigned-tls

After applying the yaml using:

$ kubectl create -f deploy_whoami.yaml -n purelb
deployment.apps/whoami created
service/whoami created
ingressroute.traefik.io/whoami created

and:

$ kubectl get services -n purelb
NAME          TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)                      AGE

traefik       LoadBalancer   10.96.141.166   192.168.0.231   80:32525/TCP,443:30543/TCP   3h24m

$ kubectl describe service whoami -n purelb

I am getting the error:

2025-07-14T10:04:51Z ERR error="kubernetes service not found: purelb/whoami" ingress=whoami namespace=purelb providerName=kubernetescrd

showing that the whoami service can not be found.

What am I missing? Thanks in advance
