ErrorException Undefined variable: post - php

Question

ok so I wanted to fetch a post from my database with my controller and then show it in my view in welcome.blade.php but the message keep showing ErrorException:
Undefined variable: post
I guess the problem is in how I write my code to get the getIndex function in my routes, so I've been trying to change that but I keep getting the same result.
so this is the line in welcome.blade.php:
<!-- Blog item -->
<div class="blog-item">
<div class="blog-thumb">
<img src="asset/img/blog/1.jpg" alt="">
</div>
<div class="blog-text text-box text-white">
<div class="top-meta"><small><i>{{ Carbon\Carbon::parse($post->created_at)->format('d-m-Y') }} by {{ $post->name }}</i></small>/ di Rakitan</div>
#foreach($posts as $post)
<h3 class="blog-post-title">{{ $post->title }}</h3>
<p>{!! \Illuminate\Support\Str::words($post->description, 30, '...') !!}</p>
<blockquote>
<p>
Learn more </p>
</blockquote>
</div><!-- /.blog-post -->
#endforeach
Lanjutkan Baca <img src="asset/img/icons/double-arrow.png" alt="#"/>
</div>
</div>
<!-- Blog item -->
this is the controller PostController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class PostController extends Controller
{
public function getIndex() {
$posts = DB::table('users')->leftjoin('posts', 'users.id', '=', 'posts.author')->paginate(2);
return view('welcome', ['posts' => $posts]);
}
}
and this is the routes file web.php
<?php
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', 'PostController#getIndex',function () {
return view('welcome')->name('index');
});
Route::get('/', 'PostController#getIndex')->name('index');
Route::get('/2019', 'BlogController#blog');
Auth::routes();
Route::get('/home', 'HomeController#index')->name('home');
Route::get('/author/post','HomeController#getPostForm')->name('post.form');
Route::post('/author/post', 'HomeController#createPost')->name('post.form');
Route::get('/author/post/detail/{id}', 'HomeController#getPost')->name('post.detail');
Route::get('/author/post/edit/{id}', 'HomeController#editPost')->name('post.edit');
Route::post('/author/post/edit/{id}', 'HomeController#updatePost')->name('post.update');
Route::get('/author/post/delete/{id}', 'HomeController#deletePost')->name('post.delete');

You are setting the meta in the HTML before you are defining post in your for loop.
#foreach($posts as $post)
<!--moved meta in here-->
<div class="top-meta"><small><i>{{ Carbon\Carbon::parse($post->created_at)->format('d-m-Y') }} by {{ $post->name }}</i></small>/ di Rakitan</div>
...
#endforeach
