Ingress Controller

Install with: helm install ingress-nginx ingress-nginx/ingress-nginx

You can watch the status by running kubectl --namespace default get services -o wide -w ingress-nginx-controller

An example Ingress that makes use of the controller:

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
  name: example
  namespace: foo
spec:
  rules:
    - host: www.example.com
      http:
        paths:
          - backend:
              serviceName: exampleService
              servicePort: 80
            path: /
  # This section is only required if TLS is to be enabled for the Ingress
  tls:
      - hosts:
          - www.example.com
        secretName: example-tls

If TLS is enabled for the Ingress, a Secret containing the certificate and key must also be provided:

apiVersion: v1
kind: Secret
metadata:
  name: example-tls
  namespace: foo
data:
  tls.crt: <base64 encoded cert>
  tls.key: <base64 encoded key>
type: kubernetes.io/tls
