Error 500 when called index.php in laravel application (Windows environment)

Question

I am deploying a laravel application inside windows based docker container using IIS. When I run the application after running docker container the server.php page present at C:\inetpub\wwwroot works fine. However, C:\inetpub\wwwroot\public\index.php returns 500 error. I have enabled the logs, run composer update and applied directory permissions as well. But still no luck.

IIS10 PHP 7.0 Laravel 5.5

The log message is

GET /public/index.php - 80 - 172.18.224.1 Mozilla/5.0+(Windows+NT+10.0;+WOW64;+Trident/7.0;+Touch;+rv:11.0)+like+Gecko - 500 19 13 1

web.config file:

<configuration>

Answer 1

From the top of my head, these are the errors that I faced when setting up laravel:

1- Directory storage permissions

2- Directory bootstrap permissions

3- composer update

4- .env file is available

5- .env key is generated

6- database is there

7- database is configured correctly in .env

8- php artisan serve if the virtual server not configured

and if i got any of those i restart the server to update the values.

if the application was a repo and gave an error, sometimes the below artisan commands save the day:

php artisan cache:clear php artisan route:clear php artisan config:clear php artisan view:clear
