Dont Worry! It is Very Easy.. 🙂

Install the Helm CLI and k3s(/or minikube) as kubernetes before the begin.

1. Create Project Tree with empty File Content like so:

.
├── Chart.yaml
├── project
│   └── index.php
├── templates
│   ├── deployment.yaml
│   ├── ingress.yaml
│   ├── pvc.yaml
│   ├── pv.yaml
│   └── service.yaml
└── values.yaml

now let’s fill in the files.

hostname: 'simple-php.local'
mountPath: 'var/www/html/'
hostPath: '/home/projects/myfirstlocalphpwithkubernetes/project'
image:
  name: php
  tag: 8.1-apache

and let’s install with helm

d8dev@d8devs:~/projects/myfirstlocalphpwithkubernetes$ helm install -f values.yaml myfirstlocalphp .

Add hostname (simple-php.local) a.k.a domain in your /etc/hosts with any text editor.

My /etc/hosts looking so;

d8dev@d8devs:~/projects/myfirstlocalphpwithkubernetes$ cat /etc/hosts
127.0.0.1       localhost
127.0.1.1       simple-php.local
......
.....

And check the domain in your browser with slash ( http://simple-php.local/ )

Enjoy!
