To Install Minikube refer - https://minikube.sigs.k8s.io/docs/start/ ( For now, this is all ready installed on your VM )

List of commands we will be using for the class -

Open a terminal on your VM and run the following commands:

To know the version of kubectl use syntax - kubectl version --client

To know the version of Minikube use syntax - minikube version

Once kubectl & minikube are installed & verified, you can now easily play around.

Just enter minikube in your terminal and you'll see a list of commands and options available to you.

Start your Cluster

Simply start a new cluster using the docker driver by using the syntax - minikube start --driver=docker command.

Hold on for some time and let minikube do its job.

Status of your Cluster

To check the status of your Cluster use syntax - minikube status

To check the ip address of the minikube - minikube ip

Managing your Cluster at any given point in time

To pause Kubernetes without impacting deployed applications use syntax - minikube pause

To Unpause a paused instance use syntax - minikube unpause

To Halt the cluster use syntax - minikube stop

To Delete all of the minikube clusters use syantax minikube delete --all

Understanding kubectl

Once your minikube cluster is up, you can start interacting with it using kubectl. kubectl actually gets installed as a dependency when we install minikube - which you can see while installing dependencies for miniKube- "kubernetes cli" is actually kubectl. One simple way of using kubectl is to get used to the command format. We've simplified this for you -

kubectl <what action do you want to do> <on which resource> -n <your namespace> <other options> <name of the resource>

kubectl

To create a namespace use syntax - kubectl create namespace my-namespace

Namespaces provides a mechanism for isolating groups of resources within a single cluster. If you don't provide a namespace, kubectl will directly use the "default" namespace for you.

To list the current namespaces in a cluster using kubectl get namespace

To get pods across all the components use syntax - kubectl get all

To get all nodes in the cluster use syntax - kubectl get node

To create a pod use syntax - kubectl run pod-name --image image_name:tag

For example using the nginx image, run the command kubectl run nginx --image=nginx --restart=Never. This will create a pod named nginx, running with the nginx image on Docker Hub. And by setting the flag --restart=Neverwe tell Kubernetes to create a single pod rather than a Deployment.

To see the status of your pod use syntax kubectl get pods

To view the entire configuration of the pod, just run kubectl describe pod nginx

To delete the pod you have created, just run kubectl delete pod nginx
