nginx container with shib auth request module

[Peter Schober]

Does anyone know of a well-maintained nginx container image that also
includes the "Shibboleth auth request module for Nginx"?
https://github.com/nginx-shib/nginx-http-shibboleth

I suppose if that were Debian-based (as is one of the officially
available flavors of the nginx containers) at least FastCGI support
would already be enabled in the Shib SP, avoiding the need to
recompile the Shib SP too in the process.
Cf. https://github.com/nginx-shib/shibboleth-fastcgi

The steps to getting all this assembled are quite involved,
esp. compared to just using Apache httpd with mod_shib:
https://github.com/nginx-shib/nginx-http-shibboleth/blob/master/CONFIG.rst#steps

That makes me wonder whether anyone is still using this or why no
docker container has emerged where all that's already been handled.
  The fact that I could only find 2 (two!) threads about this in the
last six years (assuming nginx would be in the subject) also doesn't
suggest this route to be overly popular, to put it mildly.
(Or maybe this only means that the people who manage to complete all
this simply don't require help from this community.)

Best,
