Answer 1

Since managing answers with comments is nearly impossible, I'll post the outlook of the supervisor_app.conf file here:

[program:nginx]
command = /usr/sbin/nginx -g "daemon off;"
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

I think it's what you need.

EDIT: I just saw the comment about supervisor not being found. It seems that you haven't installed it in Dockerfile. Here's how to add it:

apt-get install -y supervisor

You can add just the package name in one of the steps, like this:

RUN apt-get install -y ca-certificates supervisor

Note that you already have that line, just without supervisor.

EDIT2: As per @thsutton's answer, you also need to add nginx package, the same way you did for supervisor.

Answer 2

Does the python:3.6 image already contain nginx and supervisord? If not, it is up to you to install them (with apt-get or a similar command, as appropriate).

The fact that the nginx config file doesn't exist, and the binary doesn't exist would suggest to me that maybe the packages are not installed.
