Install kubernetes on Arch

Using root # for most of these commands, usual routine

pacman -Sy libvirt qemu ebtables dnsmasq

usermod -a -G libvirt $(whoami)
newgrp libvirt

systemctl start libvirtd.service
systemctl enable libvirtd.service

systemctl start virtlogd.service
systemctl enable virtlogd.service



pacman -S docker-machine

yay -S docker-machine-driver-kvm2
yay -S minikube kubetcl-bin

Installed?

minikube version
kubectl -h

Kubernetes Initialization with Minikube

Initialize the single-node Kubernetes cluster minikube start --vm-driver kvm2

Kubernetes has been installed on the local computer, using minikube Check:

minikube status
kubectl cluster-info
kubectl get nodes

Testing Deployments

test the kubernetes by creating a new deployment for Nginx web server

mkdir -p projects/nginx/
cd projects/nginx/

yaml file for deployment configuration: vim nginx-deployment-service.yaml

contents of yaml file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.14
        ports:
        - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  labels:
    run: nginx-service
spec:
  type: NodePort
  ports:
  - port: 80
    protocol: TCP
  selector:
    app: nginx

create the deployment: kubectl create -f nginx-deployment.yaml

check the Kubernetes deployment:

kubectl get deployments
kubectl describe deployments nginx-deployment

nginx-deployment on list ? if yes, ok.

check the Kubernetes service

kubectl get services
kubectl describe services nginx-service

check at what port 'nginx-service' runs on (PORT(S), NodePort) mine is: 31304

Check the Kubernetes cluster IP and access it using curl command

minikube ip
curl -I http://192.168.39.165:31304/

If you get response from the Nginx web server, all good. You can access same address on browser, to get webpage..
