Exercise 0.0: Starting Minikube
-------------------------------
Start Minikube without a hypervisor (a.k.a Docker runtime)::
Start Minikube with Docker::
sudo minikube start --vm-driver=none
minikube start --vm-driver='docker'
The following message should be displayed when Minikube is started successfully::
😄 minikube v1.0.1 on linux (amd64)

⚠️ The 'none' driver provides limited isolation and may reduce system security and reliability.
⚠️ For more information, see:
👉 https://github.com/kubernetes/minikube/blob/master/docs/vmdriver-none.md
⚠️ kubectl and minikube configuration will be stored in /home/ubuntu
⚠️ To use kubectl or minikube commands as your own user, you may
⚠️ need to relocate them. For example, to overwrite your own settings:
▪ sudo mv /home/ubuntu/.kube /home/ubuntu/.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
💗 kubectl is now configured to use "minikube"
🏄 Done! Thank you for using minikube!
(Optional) Note that ~/.kube/config is owned by root. Run `chown` to avoid using `sudo` all the time::
sudo chown -R $USER $HOME/.kube $HOME/.minikube

🌟 Enabled addons: storage-provisioner, default-storageclass
🏄 Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
Enable addons such as metrics-server and ingress by running the following::
minikube addons enable metrics-server
minikube addons enable ingress
Verify the right addons are enabled::

Verify that Minicube is working and you can access it. You should see the following message::
kubectl get node
NAME STATUS ROLES AGE VERSION
minikube Ready master 3m59s v1.14.3
NAME STATUS ROLES AGE VERSION
minikube Ready control-plane,master 12m v1.20.2
Now, you have a Kubernetes environment to develop and to test your workload. Never use it for production though.
