# Sample configuration:
# upstream fastcgi_backend {
#    # use tcp connection
#    # server  127.0.0.1:9000;
#    # or socket
#    server   unix:/var/run/php5-fpm.sock;
# }
## Optional override of deployment mode. We recommend you use the
## command 'bin/magento deploy:mode:set' to switch modes instead.
##
## set $MAGE_MODE default; # or production or developer
##
## If you set MAGE_MODE in server config, you must pass the variable into the
## PHP entry point blocks, which are indicated below. You can pass
## it in using:
##
## fastcgi_param  MAGE_MODE $MAGE_MODE;
##
## In production mode, you should uncomment the 'expires' directive in the /static/ location block

fastcgi_param  MAGE_MODE $MAGE_MODE;
root $MAGE_ROOT/pub;
