Trying to read from a database using laravel

I am trying to create a blog using Laravel 5.5 but I have received this error.

"Missing required parameters for [Route: posts.show] [URI: posts/{post}]. (View: /home/vagrant/Code/dialhousesetup.test/resources/views/posts/index.blade.php)"

On my postcontroller.php file. I did this so I can output all posts on my database:

public function index()
    {
        //Create a variable and store all the blog posts in it from the data base
        $posts = Post::all();

        //Return a view and pass in the above variable
        return view('posts.index', array('posts' => $posts));
    }

This is the loop I wrote on the /posts page to display all the blog posts.

<div class="events mb-100">
        <div class="container">
            <div class="row">
               @foreach ($posts as $post)
                <div class="col-md-6">
                   <a href="">
                    <div class="single-event text-center">
                        <img src="http://www.dialhousehotel.com/wp-content/uploads/2018/01/CC_1419-The-Dial-House-website-01-18-04.jpg" alt="" style="border:2px solid #bb9b50;">
                        <h2></h2>
                        <p></p>
                        <div class="separator"></div>
                        <a href=""><button type="submit" class="button button-simple mt-30">Read More</button></a>
                    </div>
                    </a>
                </div>
              @endforeach
            </div>
        </div>
    </div>

I honestly don't know what I did wrong.
