Docker Wordpress/Apache behind Docker Nginx - Port Number Issue - django

Question

I am having problems getting the wordpress docker image working with the nginx docker image.
The python/django container works perfectly fine with nginx, but the wordpress/apache one is having problems. I can get to the django site, with https. I cannot get into the wordpress one with https. In fact, when I go to my site site.com/wp, I get back site.com:8080/wp, so for some reason it is coming back through port 8080, and not 443 or 80. I've tried setting the wordpress site as the root location / (in the default.conf file) and it still has the same problem (then I get site.com:8080). The wordpress functionality is normal, I can edit the site as usual.
default.conf file for nginx
disable_symlinks off;
ssl_certificate xxx
ssl_certificate_key xxx
server {
listen 80;
return 301 https://$host$request_uri;
}
server {
listen 443 ssl;
server_name site.com;
location / {
proxy_pass http://django:8000; #django container
}
location /static {
alias /path/to/static;
}
location /wp {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_pass http://wordpress:80; #the wordpress container
}
}

It seems like the wordpress container is pulling that 8080 port number from mysql, where I had it originally set for local testing.
Overriding the mysql stored site name worked for me, by adding these lines to wp-config.php
define( 'WP_HOME', 'https://' . $_SERVER['HTTP_HOST'] . '/' );
define( 'WP_SITEURL', 'https://' . $_SERVER['SERVER_NAME'] . '/' );
