Answer 1

After installing kubectl with brew you should run:

1. rm /usr/local/bin/kubectl

2. brew link --overwrite kubernetes-cli

And also optionally:

brew link --overwrite --dry-run kubernetes-cli.

Answer 2

Your client version is too old. In my env this version comes with Docker. I have to download new client from https://storage.googleapis.com/kubernetes-release/release/v1.14.0/bin/windows/amd64/kubectl.exe and now works fine:

kubectl version
Client Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.0", GitCommit:"641856db18352033a0d96dbc99153fa3b27298e5", GitTreeState:"clean", BuildDate:"2019-03-25T15:53:57Z", GoVersion:"go1.12.1", Compiler:"gc", Platform:"windows/amd64"}
Server Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.0", GitCommit:"641856db18352033a0d96dbc99153fa3b27298e5", GitTreeState:"clean", BuildDate:"2019-03-25T15:45:25Z", GoVersion:"go1.12.1", Compiler:"gc", Platform:"linux/amd64"}

In my case, kubectl is always using google's kubectl by gcloud tool, or there was most probably a conflict between Homebrew installed and Gcloud Installed kubectl. I uninstalled Homebrew kubectl and upgrade gcloud tool to the latest, which eventually upgrades the kubectl also in the process. It resolved my issue.

I too had the same problem. In my Mac system kubectl is running from docker which is preinstalled when I install Docker. You can check this by using below command

ls -l $(which kubectl) 

which returns as

/usr/local/bin/kubectl -> /Applications/Docker.app/Contents/Resources/bin/kubectlcode.

Now we have to overwrite the symlink with kubectl which is installed using brew

rm /usr/local/bin/kubectl

brew link --overwrite kubernetes-cli

(optinal)

brew unlink kubernetes-cli && brew link kubernetes-cli

To Verify

ls -l $(which kubectl)

Answer 5

You are using the wrong kubectl version.

Kubectl is compatible 1 version up and down as described in the official docs

The error is confusing but it simply means that your version 1.10 isn't sending all the required parameters to the 1.14 api.

Answer 6

For me Docker installation was the problem. As Docker now comes with Kubernetes support, it installs kubectl along with its own installation. I had downloaded kubectl and minikube without knowing it, then my minikube was being used by Docker's kubectl installation.

Make sure that it is not also happening with you.

A second cause would be a deprecated apiVersion in your .yaml files.
