Exercise 10.1

Hi all,
I upgraded K8s to 1.18.2 and I'm still getting an error while running:
$ kubectl edit ingress ingress test
# ingresses.extensions "ingress-test" was not valid: # * : Invalid value: "The edited file failed validation": ValidationError(Ingress.spec.rules[0].http.paths[0]): unknown field "pathType" in io.k8s.api.extensions.v1beta1.HTTPIngressPath

Hi @tduszyk,
From the error provided, it seems to be an issue with the yaml of your ingress. Such issues are not fixed by cluster upgrades, but by carefully examining the yaml for incorrect indentation or unexpected configuration fields.
I suggest starting with the yaml file included in the SOLUTIONS tarball and start making edits to that in order to preserve as much of the correct indentation as possible.
In addition, I recommend reviewing the official documentation as well:
https://kubernetes.io/docs/concepts/services-networking/ingress/

I am using the file provided in the SOLUTIONS tarball, plus the necessary edits. This unknown field pathType is actually what we are being asked to add to the file.

It seems to be an older version of the file. The apiVersion is incorrect.
apiVersion
should benetworking.k8s.io/v1beta1
. You can see that in the documentation too following the link provided earlier.Have you downloaded the most up-to-date
SOLUTIONS
tarball, supporting the current course version 1.18.1? Because the latest tarball includes the file with the correctapiVersion
.Regards,
-Chris0 -
Yes, I downloaded the newest SOLUTIONS.
I rankubectl delete ingress ingress-test
to delete and recreate it usingkubectl create -f ./ingress.rule.yaml
but it didn't help. When I am trying to edit ingress, I have the wrong apiVersion. What am I doing wrong?0 -
The lab exercise works as expected on Kubernetes 1.18.1, as it is presented in the lab manual. I just ran the Ingress exercise and it all worked fine. I also downloaded a new copy of the SOLUTIONS tarball and the included
ingress.rule
file shows the correctapiVersion
.What was your Kubernetes version before the upgrade to 1.18.2? Did you upgrade all your nodes to 1.18.2? Things may change between minor versions also, so expect things to behave differently when running the labs on a different version than the one presented in the manual.
You can also try editing the
ingress.rule
file right before creating the ingress resource. Have you tried that instead?Regards,
-Chris0 -
Thank you Chris.
I ended up redeploying fresh Ubuntu 18.04 VMs and installing K8s 1.18.1-00. It's working now as expected.
