I would like to install laravel 8 with php version 8 but my local php version is 7.4 so I'm opting for laravel sail. Docker is already installed and docker-compose.yml has

    context: ./vendor/laravel/sail/runtimes/8.0

Now according to documentation when I try to

    composer require laravel/sail

Or

   php artisan sail:install

It gives me dependency error or php version. How do I create docker container with laravel sail? Do I need to create a separate docker container with correct php version and run laravel sail inside that?
