Problem with Krew “Error: flags cannot be placed before plugin name”

7/27/2021

I have a local minikube cluster (version: v1.21.0) with kubectl:

Client Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.7", GitCommit:"132a687512d7fb058d0f5890f07d4121b3f0a2e2", GitTreeState:"clean", BuildDate:"2021-05-12T12:40:09Z", GoVersion:"go1.15.12", Compiler:"gc", Platform:"linux/amd64"}

Server Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.7", GitCommit:"132a687512d7fb058d0f5890f07d4121b3f0a2e2", GitTreeState:"clean", BuildDate:"2021-05-12T12:32:49Z", GoVersion:"go1.15.12", Compiler:"gc", Platform:"linux/amd64"}

I installed krew according to the documentation: https://krew.sigs.k8s.io/docs/user-guide/setup/install/

Then, when I try to execute any command this is the result:

Error: flags cannot be placed before plugin name: --cluster

For example:

minikube kubectl krew version
Error: flags cannot be placed before plugin name: --cluster
-- glidercode
kubectl
kubernetes
minikube

Why you are running the minikube in command before the kubectl

minikube kubectl krew version

You can set and use the context of K8s using this command

kubectl config use-context CONTEXT_NAME

Using the kubectl only you can access the Krew and install the plugins

kubectl krew install access-matrix

example 

kubectl access-matrix
