I achieved to connect my docker container to aapanel php-fpm now, but all sites go down. For my lucky, the panel was updated and my php-fpm configs was rewrited. I think I need to keep aapanel php-fpm and make a php-fpm container instead. I'm saying this to other person that pass here.
it was just me saying that the new docker update appeared. But I'm clicking in install in the docker aapanel session and nothing happens.
