passenger_ruby

docker image with passenger and ruby

viene utilizzato passenger standalone che ascolterà sulla porta 80
fuori dal container sarà presente nginx che girerà quando opportuno le richieste a passenger

il sistema presuppone che l'applicativo sia posizionato nella solita cartella /var/www

Ci sono tre file inseriti in automatico nel sistema di boot:
/etc/my_init.d/a_install.sh
/etc/my_init.d/b_migrate.sh
/etc/my_init.d/c_precompile.sh
basta cancellarli per non lanciare le varie funzionalità.
