找不到 Minikube 标志

Question

I have a problem with minikube when I want to create deployment manifest files, I receive an error when I write this code: minikube kubectl create -f. I got this Error:

Error: unknown shorthand flag: 'f' in -f See 'minikube kubectl --help' for usage.

but not only this, I try to write another command but again same error happening

minikube kubectl delete daemonsets,replicasets,services,deployments,pods,rc,pvc --all Error: unknown flag: --all See 'minikube kubectl --help' for usage.

please help me. thanks

AFAIK, --all is not a valid flag. Valid flag is --all-namespaces or just -A.

However, "kubectl delete" does not take -A as it needs the resource name for deletion.

To accomplish what you are trying to do you will have to write a loop to delete the objects 1 by one using

kubectl get daemonsets,replicasets,services,deployments,pods,rc,pvc -A --no-headers | while read line; do 
    namespace=$(echo $line | awk '{print $1}')
    resource=$(echo $line | awk '{print $2}')
    kubectl delete ${resource} -n ${namespace}
done

Execution - BE extremely careful with this as it will delete all queried resources in all namespaces including those in kube-system namespace :

controlplane $ kubectl get daemonsets,replicasets,services,deployments,pods,rc,pvc -A --no-headers | while read line; do 
>     namespace=$(echo $line | awk '{print $1}')
>     resource=$(echo $line | awk '{print $2}')
>     kubectl delete ${resource} -n ${namespace}
