Symfony2 - doctrine:create in Production
Ahaha there are different schools for that.
Startup way: doctrine:schema:create first time in production, doctrine:schema:update --force every updates
Cautious way: dump sql first time, sql scripts then for updates
Expert way: http://symfony.com/doc/master/bundles/DoctrineMigrationsBundle/index.html
Personally I use the first method, which works just fine. You could always do a --dump-sql to see what's going on before updating using --force
