ConnectionString? It's also downside that I can't manually interfere with database. Another thing is SSL, I found out that I need to use Certbot to get certificate and automatically renew it, are there no configurations needed other than just something like sudo certbot --nginx -d domain.com? and also, I am supposed to make first deployment with SSH? or do I need to make specific actions before that. Lastly, is it safe to save ConnectionString as environment variable?
