I am trying to configure Basic Authentication on a Nginx example with Traefik as Ingress controller.

I just create the secret "mypasswd" on the Kubernetes secrets.

This is the Ingress I am using:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginxingress
  annotations:
    ingress.kubernetes.io/auth-type: basic
    ingress.kubernetes.io/auth-realm: traefik
    ingress.kubernetes.io/auth-secret: mypasswd
spec:
  rules:
  - host: nginx.mycompany.com
    http:
      paths:
      - path: /
        backend:
          serviceName: nginxservice
          servicePort: 80

I check in the Traefik dashboard and it appear, if I access to nginx.mycompany.com I can check the Nginx webpage, but without the basic authentication.

This is my nginx deployment:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80

Nginx service:

apiVersion: v1
kind: Service
metadata:
  labels:
    name: nginxservice
  name: nginxservice
spec:
  ports:
    # The port that this service should serve on.
    - port: 80
  # Label keys and values that must match in order to receive traffic for this service.
  selector:
    app: nginx
  type: ClusterIP
