Laravel5 connection with sqlite db works with php artisan but not from website

I am puzzled with one interesting problem.

In my .env laravel 5 app file setup, I have following environments variable(clearly this is for production setup with mysql which I am overriding in my docker run command) in my container by passing the different names for sqlite)

DB_CONNECTION=mysql
DB_HOST=database
DB_PORT=3306
DB_DATABASE=homestead

Here is my config/database.php :

 'connections' => [

        'sqlite' => [
            'driver' => 'sqlite',
            'database' => env('DB_DATABASE', database_path('my-sqllite-db.sqlite')),
            'prefix' => '',
        ],

I am using sqlite on my docker based local php-fpm and nginx (multiservice) container. I build the docker image (my_app_img) and pass following environment variable to run docker container

docker run -p 80:80 --name MyApp -d -e "DB_CONNECTION=sqlite" -e "DB_DATABASE=database/my-sqllite-db.sqlite" -e "DB_HOST=127.0.0.1" my_app_img

After this when I do :

docker exec container_ID php artisan migrate

This works on on terminal and shows that it is successful to connect to sqlite file.

But when I then try to register my user on a webpage, which is supposed to now hit the sqlite db (as I have also finished my migration), I get following error :

Database (database/my-sqllite-db.sqlite) does not exist. (SQL: select count(*) as aggregate from "users" where "name" = "Andrew:

Anyone has any insight into why the php artisan was able to use the sqlite connection properly but webpage is not able to use this connection?
