Description Nikos Stamatelopoulos 2022-04-13 08:32:50 UTC
Description of problem:

The kubectl client included in the oc client downloadable file returns the below output when one runs kubectl version:

./kubectl version

Client Version: version.Info{Major:"1", Minor:"23", GitVersion:"v0.23.0", GitCommit:"346b183f7b5ea13b052f0f7e27e6196b803cde94", GitTreeState:"clean", BuildDate:"2022-03-27T11:28:37Z", GoVersion:"go1.17.5", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"22", GitVersion:"v1.22.3+b93fd35", GitCommit:"3a0f2c90b43e6cffd07f57b5b78dd9f083e47ee2", GitTreeState:"clean", BuildDate:"2022-02-11T05:26:59Z", GoVersion:"go1.16.12", Compiler:"gc", Platform:"linux/amd64"}
WARNING: version difference between client (0.23) and server (1.22) exceeds the supported minor version skew of +/-1

When the oc client v4.10.8 was downloaded by our portal [0] and with it is included in the tar file the kubectl client as well.

So when i run the "kubectl version" command i can see the above Warning.

In the repository there are both tags kubernetes-1.23 (with the Major) and v0.23 (without the Major). Also, i cannot find the commits indicated with each version

Version-Release number of selected component (if applicable):

The version is 4.10.8 but I reproduced the issue with 4.9 and 4.7 oc clients.

[0]https://access.redhat.com/downloads/content/290/ver=4.10/rhel---8/4.10.8/x86_64/product-software

How reproducible:


Steps to Reproduce:
1. Download the client from our portal [0]
2. Login to a 4.9-4.10 cluster
3. Unzip and run the "kubectl version"

Actual results:

There is a Warning of version mismatch dispite the fact that the client is the same version with the cluster

Expected results:

There should be no such warning
