=====Overview=====
Minikube is a taste of Kubernetes, it is a single pod single master configuration, but it gives you a taste of the Kubernetes. The installation is very simply:


=====Installation=====
<Code:bash|Install Minikube>
root@k8s-master:/etc/apt# curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \
>   && chmod +x minikube
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 52.0M  100 52.0M    0     0  13.2M      0  0:00:03  0:00:03 --:--:-- 13.2M
root@k8s-master:/etc/apt# mkdir -p /usr/local/bin/
root@k8s-master:/etc/apt# install minikube /usr/local/bin/
</Code>

Once that is done, we can start it:

<Code:none|Start Minikube>
root@k8s-master:/etc/apt# minikube start --vm-driver=none --apiserver-ips 127.0.0.1 --apiserver-name localhost

❗  The 'none' driver provides limited isolation and may reduce system security and reliability.
❗  For more information, see:
👉  https://minikube.sigs.k8s.io/docs/reference/drivers/none/

❗  kubectl and minikube configuration will be stored in /root
❗  To use kubectl or minikube commands as your own user, you may need to relocate them. For example, to overwrite your own settings, run:

    ▪ sudo mv /root/.kube /root/.minikube $HOME
    ▪ sudo chown -R $USER $HOME/.kube $HOME/.minikube

💡  This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true
