I have been using minikube with the kvm2 driver to run a test kubernetes environment which I use for my tests. In here I document the steps I took to install minikube on my Fedora machine.
Minikube with kvm is intended to be run by a non-privileged user. In my case, I am use a user which is part of the libvirt group to allow the user to create vms.
Download and install the latest minikube package. This has to be run as root or a user with sudo access.
$ sudo dnf install https://storage.googleapis.com/minikube/releases/latest/minikube-latest.x86_64.rpm
Start up minikube. The command below downloads a kvm image which it then uses to create a virtual machine called minikube. You can see this running by calling 'virsh list' as a root user.
$ minikube start --driver=kvm2

💡 kubectl not found. If you need it, try: 'minikube kubectl -- get pods -A'
🏄 Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
Instead of passing the option --driver=kvm2, you can also set kvm2 to be the default driver.
$ minikube config set driver kvm2
To check status of minikube,
$ minikube status
minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured
timeToStop: Nonexistent
Before we can use minikube, we need to install the kubectl utility to access the kubernetes cluster.
As root or a user with sudo access, install package kubernetes-client.
$ sudo dnf install kubernetes-client
kubectl uses the config file under ~/.kube/config
To check if minikube is setup correctly, you can check the version of the client and the server with the command
$ kubectl version
