Web and CLI mysql won't connect at the same time - php

Question

I have setup my Laravel application using Laravel Sail (Docker based). Everything's working fine except the MySQL. MySQL server is behaving differently for web (local.mysite.com:8080) and for CLI (ex: php artisan migrate).
Configruation (1)
If I use the following configuration in my .env file,
...
APP_DOMAIN=local.mysite.com
...
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=mydb
DB_USERNAME=root
DB_PASSWORD=root
FORWARD_DB_PORT=3307
the web works, not the CLI. When I run php artisan migrate command I get SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
Configuration (2)
And if I use the following configuration,
...
APP_DOMAIN=local.mysite.com
...
DB_CONNECTION=mysql
DB_HOST=local.mysite.com
DB_PORT=3307
DB_DATABASE=mydb
DB_USERNAME=root
DB_PASSWORD=root
FORWARD_DB_PORT=3307
The CLI works fine, not the web. I get a Connection Refured error by MySQL on web.
I've been banging my head with different tries, no luck...
What am I doing wrong?
Here's my docker-compose.yml for reference (phpmyadmin is working real good btw):

Answer 1

I realized my mistake.
I should be using sail artisan migrate instead of php artisan migrate as clearly explained in the official Laravel Sail documentation.
The correct configuration therefore is:
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=mydb
DB_USERNAME=root
DB_PASSWORD=root
FORWARD_DB_PORT=3307
