1) laravel new <project-name>
2) composer require laravel/ui
3) php artisan ui vue --auth
4) npm install tailwindcss
5) resources/sass/app.scss replace whats inside with:
  @import "tailwindcss/base";
  
  @import "tailwindcss/components";
  
  @import "tailwindcss/utilities";
  
4) touch tailwind.config.js (root directory):
  module.exports = {
    purge: [],
    theme: {
      extend: {},
    },
    variants: {},
    plugins: [],
  }
  
5) webpack.mix.js:

  const mix = require('laravel-mix');
  const tailwindcss = require('tailwindcss');
  
  mix.disableNotifications();
  
  mix.js('resources/js/app.js', 'public/js');
  
  mix.sass('resources/sass/app.scss', 'public/css')
  .options({
     processCssUrls: false,
     postCss: [ tailwindcss('./tailwind.config.js') ],
  })

# docker run examples:
docker run --rm -it 1kg_portal #this creates an interactive containter on image
named (1kg-portal) and it will remove this container when you exit

on command line type journalctl -xe and the results will be

SELinux is preventing /usr/sbin/httpd from name_bind access on the tcp_socket port 83 or 80

Then find the line SELINUX=enforce and change to SELINUX=disabled

Then type the following and run the command to start httpd

setenforce 0

Lastly start a server

systemctl start httpd
