Draft!

Installation steps

Install kubectl

• $ grep -E --color 'vmx|svm' /proc/cpuinfo
• $ curl -LO https://storage.googleapis.com/kubernetes-release/release/curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl`

• $ sudo apt install libvirt-clients libvirt-daemon-system qemu-kvm && sudo usermod -a -G libvirt $(whoami) && newgrp libvirt

• $ sudo virt-host-validate

Install Minikube

• $ curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube
• $ sudo mkdir -p /usr/local/bin/
• $ sudo install minikube /usr/local/bin/

Check

• $ minikube start --vm-driver=<driver_name>, where <driver-name> kvm2 or set one of list of drivers

• $ minikube status

  Output:

  host: Running
  kubelet: Running
  apiserver: Running
  kubeconfig: Configured

• $ minikube stop

Clear local state
