Exercise 10.1: Advanced Service Exposure - error in the code
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: ImplementationSpecific1 -
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

Please update that info in the course. Even though the API gets changed rather frequently it's your responsibility as the course provider to keep this information up to date. The issue was posted some time ago and the course is still not up to date. This wastes time for your students to go and look for this information. One thing is when something new pops up and you are not aware of it and another is to deliberately avoid adding value to the course and keeping it up to date when a new issue is brought to light.
I would also recommend reviewing the whole course since as of 6/9/2021 there are dozens of typos and other mistakes. For example, in this very same lab point 6 says to issue the following command:
student@master: ̃$ cp ./LFS458/SOLUTIONS/s_10/traefik-ds.yaml .
I think it's obvious that the name of the course as well as the tarball is wrong. I found a lot of other typos and grammar mistakes. The course needs further review.
Thank you for the solution, cheers!

Hello,
A new version of the course will be released soon.
What version of the course are you using? In my version it is very clear to use the output of the find command. Does your direct you to use that or not?

There is no archive like LFS458 - https://training.linuxfoundation.org/cm/LFS258/. I believe the correct one is LFS258_V2021-02-05_SOLUTIONS.tar.xz. Once you unzip it the name is LFS258. Anyway, the version I use is the latest available. My point was that there are a lot of typos and grammar mistakes in the course. I remember seeing wrong pod names in commands, I didn't write all of it down.
