kubectl describe ingress not working (1.15.0 against 1.12.7 server)

[dustin-decker]

$ k get ingress some-app

It works if I downgrade kubectl to 1.12.7

[dustin-decker]

https://github.com/kubernetes/kubernetes/pull/74057 seems to be related.

kube-apiserver logs indicate that get uses the extensions/v1beta1 api, and describe uses the networking.k8s.io/v1beta1 api:

I0709 01:37:46.517128       1 wrap.go:47] GET /apis/extensions/v1beta1/namespaces/some-namespace/ingresses/some-app: (5.16454ms) 200 [kubectl/v1.15.0 (linux/amd64) kubernetes/e8462b5 52.11.64.245:51960]

This is the yaml output of the resource (using the deprecated ingress):

Same problem! Version 1.12.7 works fine.

[otakumike]

I also encountered this problem running client 1.15.0 against a 1.13.7-gke.8 server:

Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.0", GitCommit:"e8462b5b5dc2584fdcd18e6bcfe9f1e4d970a529", GitTreeState:"clean", BuildDate:"2019-06-20T04:49:16Z", GoVersion:"go1.12.6", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"13+", GitVersion:"v1.13.7-gke.8", GitCommit:"7d3d6f113e933ed1b44b78dff4baf649258415e5", GitTreeState:"clean", BuildDate:"2019-06-19T16:37:16Z", GoVersion:"go1.11.5b4", Compiler:"gc", Platform:"linux/amd64"}

Downgrading to client 1.14.3 solved it:

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/fcb6cce3bdd37db3c53c2fcbdf9a47671a592c96/Formula/kubernetes-cli.rb

Please note that Kubernetes version skew policy is to provide a kubectl that is guaranteed to work against an API Server that is +/- 1 version. So for the initial scenario of a 1.12 API Server, kubectl version 1.11, 1.12, and 1.13 are guaranteed to work. Closing this issue.

[clehene]

@seans3 perhaps a version compatibility warning would be useful to avoid time spent troubleshooting this..

[Prakashreddy134]

@seans3: Closing this issue.

Hi,
I'm getting "Error from server (NotFound): the server could not find the requested resource" while running describe ingress command . Client and server versions is v1.15.0 ,v1.13.6
Please help me.

[demisx]

@Prakashreddy134 Try matching your kubectl version to your server version.

[BenjaminSchiborr]

@demisx, how would you best handle multiple Kubernetes clusters on different versions if you have to match kubectl client to the server version?

[ebn-rec]

@demisx I think you should reopen this. Users are likely going to have the most recent kubectl version and maintaining old version is not a viable solution.

[demisx]

@BenjaminSchiborr Perhaps, via different docker containers?

@ebn-rec I can't reopen this issue, since I am neither the author, not a member of this project with sufficient rights to do so. I just ran into this issue myself today and matching kubectl version to the server version fixed the problem.

[vrobert78]

We have clusters on GKE in the last stable version v1.13.7-gke.19.

Our workstation are on Ubuntu 18.04.3 LTS, we use the repo "deb http://packages.cloud.google.com/apt cloud-sdk-bionic main" for gcloud and kubectl.
Kubectl is in v1.15.3.

Could you re-open this issue please ?

[noeljackson]

Same situation. Details below:

$ kubectl describe ingresses.extensions 
Error from server (NotFound): the server could not find the requested resource

$ kubectl version

[lindhe]

Why not display a warning, if the client and server versions don't match?

[seans3]

Adding a warning for violating the support window is a great suggestion. I suggest we move this discussion over to this new issue: https://github.com/kubernetes/kubectl/issues/709

[advissor]

Will leave it here for those who might struggle :

1) Verify client & server versions of kubectl by
kubectl version
2) Check the skew policy and select appropriate client binary for download
https://kubernetes.io/docs/tasks/tools/install-kubectl/
3) Download the binary with curl for example > chmod > move
Like here : https://kubernetes.io/docs/tasks/tools/install-kubectl/

I have the same problem. Below the output of kubectl version:

Why the issue is closed ?

Issue is closed , because there is no bug.
This suppose to work like this and compatible client<>server versions are mentioned in skew policy
In your case Client v1.15.3 -> Server v1.12.10-eks-825e5d
Basically, this is out of compatibility. What you can do in order to fix the issue is to downgrade the client to v1.13.10 for example. This should work

Hi,

is there a way to install via apt-get an old version of kubectl ?

I've tried to install the 1.13.7, but it doesn't work:

apt-get install kubectl=1.13.7-00
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances       
Lecture des informations d'état... Fait
E: La version « 1.13.7-00 » de « kubectl » n'a pu être trouvée

apt-cache policy kubectl
kubectl:
  Installé : 1.15.3-00
  Candidat : 1.15.3-00
 Table de version :
 *** 1.15.3-00 500
        500 http://packages.cloud.google.com/apt cloud-sdk-bionic/main amd64 Packages
        100 /var/lib/dpkg/status

Do you know how to contact a person in charge of packages.cloud.google.com/apt ?
It could be very interesting that they maintain multiple version.

Just give it a try in a way mentioned in official page:
https://kubernetes.io/docs/tasks/tools/install-kubectl/

For example:

curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.13.10/bin/linux/amd64/kubectl

Where in v1.13.10 you need to substitute specific client version you need
