Exercise 10.1: Advanced Service Exposure - error in the code

shinhf

I am using kubernetes v1.20.

I noticed that in point 8 (creating ingress yaml) the structure of the rule yaml looks like that:
http:
paths:
- backend:
serviceName: secondapp
servicePort: 80
path: /

After starting ingress. In point 15 there is the task to edit the rules.
It looks like kubernetes reformatted the configuration (code from pdf is not working)

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

Hi @shinhf,

As Kubernetes matures, minor changes in the API are expected, especially when a resource advances from beta to stable level of support. Comparing lab exercises with the documentation is recommended to catch such minor changes in the API resource definitions, commands, arguments, flags, and options.

Yep, this ingress.rule.yaml worked for me:

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

Hi @guillermotti,

The Code markups from the Format menu help to preserve the YAML indentation.

Sorry for that, this is the preserved YAML:

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