deleting minikube cluster so I can create a larger cluster with more CPUs

I need to run sudo minikube start --memory=4096 --cpus=2 for my use case. However it is running with 1 cpu already. Somehow I started it w/o creating an entry in ~/kube/config so "kubectl config delete-cluster minikube" returns, "error: cannot delete cluster minikube, not in /home/ec2-user/.kube/config".

Trying to work around this, to delete my cluster and start with a larger one, I ran, "kubectl config set current-context minikube". Which created this entry in .kube/config: cat .kube/config

apiVersion: v1

clusters: null

contexts: null current-context: minikube

kind: Config

preferences: {}

users: null

NOTE: ignore double spaces I had to enter carriage returns to get the proper format)

Anyone know how to delete my current cluster, so I can create a bigger one with more memory and cpus?

I run minikube with --driver=dockerand 1 cpu, using this command :

minikube start --driver=docker --extra-config=kubeadm.ignore-preflight-errors=NumCPU --force --cpus 1

So if I want to delete minikube and all its files, I use those two commands:

minikube stop

minikube delete --all=true --purge=true

then you can run minikube with your specifications :

minikube start --memory=4096 --cpus=2

To change cpus or memory you want to get the profile name like mentioned before:

minikube profile list

And then delete the profile you want to change, in my case it was minikube:

minikube delete --profile minikube

Then you can start minikube again creating new profile:

minikube start --vm-driver=virtualbox --cpus 8 --memory 16g

You'll need to run minikube stop, then you should be able to start minikube again with more resources (minikube start --memory=4096 --cpus=2).

No need to delete your cluster.
