How to configure ExecStart for Gunicorn without WSGI?

Systemd and Gunicorn require a wsgi file of some sort as the last arg to ExecStart: http://docs.gunicorn.org/en/latest/deploy.html?highlight=ExecStart#systemd

With Django, this was in the main module as wsgi.py:

ExecStart=/home/admin/django/bin/gunicorn --config /home/admin/src/gunicorn.py --bind unix:/tmp/api.sock myapp.wsgi

But this file obviously doesn't exist when using Sanic and uvloop (I believe the new protocol is called ASGI). I tried substituting it for app.py which unsurprisingly didn't work:

ExecStart=/home/admin/sanic/bin/gunicorn --config /home/admin/src/gunicorn.py --bind unix:/tmp/api.sock myapp.app

How should this parameter be configured when using Sanic?

sanic uvloop gunicorn systemd

If you want to start sanic with systemd, why don't you used supervisrod: Supervisord.

Boot -> Systemd -> supervisord -> gunicorn -> sanic

[unix_http_server]
file=/tmp/supervisor.sock                       ; path to your socket file

[supervisord]
logfile=/var/log/supervisord/supervisord.log    ; supervisord log file
logfile_maxbytes=50MB                           ; maximum size of logfile before rotation
logfile_backups=10                              ; number of backed up logfiles
loglevel=error                                  ; info, debug, warn, trace

nodaemon=false                                  ; run supervisord as a daemon
minfds=1024                                     ; number of startup file descriptors
minprocs=200                                    ; number of process descriptors

[supervisorctl]
serverurl=unix:///tmp/supervisor.sock         ; use a unix:// URL  for a unix socket
