Docker change wordpress to HTTPS from HTTP - wordpress

Question

I struggle to change configuration of already set-up container to use SSL.
I have VPS with CentOs 8, on which I have 2 containers running, one with Wordpress and other with wordpress DB. Wordpress works fine on port 80. I'd like to enable SSL and move it to 443.
Right now what I did:
Open firewall port 443 for docker trusted interface;
Changed wp-config.php with wp-home and wp-site url to use respectively https protocols;
Added FORCE_SSL_ADMIN in wp-config.php
In stoped container changed hostconfig.json and config.v2.json to use respectively 443 protocols to 80
EDIT 1
Current outcome:
When running curl localhost:443 I got wordpress page returned (from local machine to wordpress), however I do not think it uses https protocol.
Desired outcome:
I'd like to be able to serve wordpress over https for external traffic. Right now I got connection refused message.

If I were you I wouldn't bother doing anymore config at container level, rather I'd use an application server like Nginx or Apache to resolve DNS and redirect incoming traffic to the containers via reverse proxy.
If this is not possible, could you please provide the (I'm assuming) docker-compose file and dockerfiles you have to set up your server?
EDIT:
Don't run the docker container on 443, it can listen internally on any port you want, but map it to something else, like 8080, for the following example config.
nginx.conf
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
gzip on;
server {
listen 80;
server_name example.com;
rewrite ^ https://$host$request_uri permanent;
}
server {
listen 443 ssl http2;
server_name example.com;
ssl on;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/privkey.key;
location / {
proxy_pass http://127.0.0.1:8080;
}
}
}
