Lab 7 review ingress controller

Hello,

Were you able to find YAML examples of working with an existing ingress controller when looking among the allowed domains?

Regards,

There doesn't seem to be one good example of apiversion v1 with an annotation (e.g. kubernetes.io/ingress.class: traefik ) and an ImplementationSpecific pathType.

Hi @chrispokorni ,

Unfortunately, I can not find any ingress installation section in the Kubernetes documentation.
Even not in https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/.
Will there be some guide in the exam, in case I need to install an ingress controller during the exam?

Best regards,
Benni

Hello,

This info may also help. The nginx folks had a breaking change 2 days ago:

https://github.com/kubernetes/ingress-nginx/releases/tag/controller-v1.0.0

If you miss the ingressclass the controller gives you:

"Ignoring ingress because of error while validating ingress class" ingress="default/ingress-test" error="ingress does not contain a valid IngressClass"

So a quick fix is adding the annotation for the ingress class to your ingress.yaml Otherwise the whole ingress part of lab 7 will not work.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-test
  namespace: default
  annotations:
    kubernetes.io/ingress.class: "nginx"
spec:
  rules:
  - host: www.example.com
    http:
      paths:
      - backend:
          service:
            name: secondapp
            port:
              number: 80
        path: /
        pathType: ImplementationSpecific
  - host: thirdpage.org
    http:
      paths:
      - backend:
          service:
            name: thirdpage
            port:
              number: 80
        path: /
        pathType: ImplementationSpecific
