doesn't work behind reverse-proxy

[mikekuzak]

Hi,

Tried to run this behind a reserve-proxy (traefik 2.0)

Some files are trying to add always the default port to the dns https://observium.containers.mycompany.com:**8668**/js/jquery.min.js?v=20.9.10731

instead of

https://observium.containers.mycompany.com/js/jquery.min.js?v=20.9.10731

Is there a way to pass in the host dns/port ? Similar to this one: https://github.com/somsakc/docker-observium#a-manual-run-containers

You can edit the $config['base_url'] property in config.php after the first run. If you want it to work like the other container where you can pass in an environment, you could submit a pull request to do so.

Another solution and a better solution is to use HTTP request headers:

$_current_headers = apache_request_headers();

$_url_scheme = $_current_headers['X-Forwarded-Proto'] ?? 'http';
$_url_host = $_current_headers['X-Forwarded-Host'] ?? $_SERVER['SERVER_NAME'];
$_url_port = $_current_headers['X-Forwarded-Port'] ?? $_SERVER['SERVER_PORT'];
$config['base_url'] = $_url_scheme . '://' . $_url_host . ':' . $_url_port;

Edit config.php file allowing to configure the base_url setting

This breaks the observium cron with the following error.
