wordpress+docker+apache mod proxy redirects to http://localhost

My environment is, a docker container running wordpress on apache can be accessed via ip:port . The host environment has an apache instance which redirects traffic that comes to http://myurl to localhost:port using mod proxy (I have the same set up with other docker containers in the same host which is working fine). But accessing http://myurl (after changing the wordpress config) will just redirect you to localhost (in the wordpress container's apache log i can see it giving a 301 to redirect you) .

The problem is only there when you access the base url. (http://myurl/wp-login.php works)

Host Apache config:

<VirtualHost *:80>
    ServerName my.url.com
<IfModule mod_proxy.c>
ProxyRequests Off
ProxyPass         /   http://localhost:8080/
ProxyPassReverse  /   http://localhost:8080/
</IfModule>
</VirtualHost>

This works (in wp-config.php):

define('WP_HOME','http://8.8.8.8:8080');
define('WP_SITEURL','http://8.8.8.8:8080');

This doesn't

define('WP_HOME','http://my.url.com');
define('WP_SITEURL','http://my.url.com');

These are the wordpress plugins i have enabled. But note that i changed their configs accordingly as well.

  1. wp-support-plus
  2. admin custom login

UPDATE: This seems to have fixed the problem somewhat.

define('WP_HOME','http://8.8.8.8:8080');
define('WP_SITEURL','http://my.url.com');

Some of the components (home buttons etc) still go for the ip:port but the system works.

Turns out the problem is the headers being stripped when the redirection happens. I fixed this by adding ProxyPreserveHost On to the host apache configuration. The changed file looks like this now.

Host Apache config:

<VirtualHost *:80>
    ServerName my.url.com
<IfModule mod_proxy.c>
ProxyRequests Off
ProxyPreserveHost On # needed if you need to pass the original host header
ProxyPass         /   http://localhost:8080/
ProxyPassReverse  /   http://localhost:8080/
</IfModule>
</VirtualHost>
