Minikube

Minikube allows you to run a Kubernetes cluster locally.

Installation

1. Install Minikube on your Virtual Machine:

   curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
   sudo install minikube-linux-amd64 /usr/local/bin/minikube
   sudo minikube config set vm-driver none
   

Note: If you have VirtualBox installed, you can specify vm-driver=VirtualBox

2. Install kubectl:

   curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
   chmod +x kubectl
   sudo mv ./kubectl /usr/local/bin/kubectl
   

3. Start Minikube:

   minikube start
   

4. You can check your kubectl installation running the following command:

   kubectl get pods --all-namespaces
   

This should list all the kube-system pods currently running on the machine.

5. Create a Deployment

   kubectl create deployment --image nginx my-nginx
   kubectl expose deployment my-nginx --port=80 --type=NodePort
   kubectl get svc
   

6. Start Dashboard

To view your minikube dashboard, run the following command.

    minikube dashboard --url &

This might throw an error depending on what’s installed on your machine. To access your dashboard you need to run Kubeproxy.

8. Kubeproxy

   kubectl proxy --address=0.0.0.0 --accept-hosts='.*'
   

9. View Minikube Dashboard

To view your minikube dashboard from your web browser, run the following command:

    http://{host_ip}:8001/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/

    (Replace host_ip with the ip address of your VM)

10. Delete Cluster

    minikube delete
