Getting Started with Minikube on Fedora 30

Introduction

To install Minikube there are 3 things to do:

1. Install a hypervisor, e.g. VirtualBox, KVM
2. "Install" (download and add in path) kubectl
3. "Install" (download and add in path) Minikube

Install kubectl

Reference: https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-on-linux

$ 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

$ kubectl version

Install MiniKube

$ wget https://github.com/kubernetes/minikube/releases/download/v1.6.0-beta.1/minikube-1.6.0.beta.1.rpm .
    
$ sudo rpm -pi minikube-1.6.0.beta.1.rpm

$ sudo rpm -ql minikube
/usr/bin/minikube

$ sudo rpm -q --scripts minikube

Test

https://kubernetes.io/docs/setup/learning-environment/minikube/

Start Minikube and create a cluster. Here I specify VirtualBox as hypervisor, since I have also KVM installed.

$ minikube start --vm-driver=virtualbox

Deploy image 'k8s.gcr.io/echoserver' version 1.10 and name deployment 'hello-minikube'.

$ kubectl create deployment hello-minikube --image=k8s.gcr.io/echoserver:1.10

Expose deployment on NodePort and port 8080, i.e. create routing.

$ kubectl expose deployment hello-minikube --type=NodePort --port=8080

Check deployment has finished.

$ kubectl get pod

Retrieve internal IP and port and access web app.

$ minikube service hello-minikube --url
http://192.168.99.100:30024

$ curl http://192.168.99.100:30024
