Getting started with Kubernetes Gateway API and Traefik

Blog

I was able to get things working after doing the following:

  1. installing the Traefik RBAC
  2. creating a namespace
kubectl create namespace whoami
  1. commenting out hostnames section and applying whoami application YAML to the cluster
# Application to expose
kind: Deployment
apiVersion: apps/v1
metadata:
  name: whoami
  namespace: whoami
spec:
  replicas: 3
  selector:

      app: whoami
  template:

      labels:
        app: whoami
    spec:
      containers:
        - name: whoami
          image: traefik/whoami
