$ supervisorctl

You should run supervisorctl with -c as well. From the documentation (my emphasis):
The Supervisor configuration file is conventionally named supervisord.conf. It is used by both supervisord and supervisorctl. If either application is started without the -c option (the option which is used to tell the application the configuration filename explicitly), the application will look for a file named supervisord.conf within the following locations, in the specified order. It will use the first file it finds.
CWD/etc/supervisord.conf
/etc/supervisord.conf
