Deploy multiple laravel apps to digital ocean droplet using Docker

Hello, ive been struggling all day what is the appropiate way to deploy multiple apps on a single droplet using docker. I successfully deployed 1 app but what about deploying a second on same droplet? Should i use a reserve proxy? Should i use 1 nginx and mysql container for all apps, or every app has its own? Should i make ssl certificate for every app or can i make only 1 for all apps? Can not find anywhere a video showcasing this scenario.

server {
    listen 443 ssl;

    index index.php index.html;
    server_name mydomain.com;
    root /var/www/html/public;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location /.well-known/acme-challenge/ {
        root /var/www/certbot;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

    ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem;
}
