Tile fetching behind reverse proxy

[papaya147]

I've deployed this container on a Kubernetes cluster. I am connecting a service to my ingress to proxy to this container. I am able to access the http service at domain.com/overv. But when tiles are trying to be loaded, it's trying to fetch tiles from domain.com/tiles/..., whereas I want it to fetch from domain.com/overv/tiles/... . Is there any way to let the container know it's behind a reverse proxy?

The problem is, that the absolute path is hardcoded. https://github.com/Overv/openstreetmap-tile-server/blob/6088b9b37f440f141f643f413a3d6454a1c01aa2/leaflet-demo.html#L28

You could volume mount your own .html file over /var/www/html/index.html that changes the path.

If you are using apache as the proxy, there are settings that might be able to deal with these kind of problems:

• ProxyPassReverse of mod_proxy can change paths in the HTTP headers (e.g. to fix paths in redirects). But that won't help with the hardcoded path in the HTML.
• ProxyHTMLURLMap of mod_proxy_html allows to change links in HTML responses, but as far as I see that is limited to specific HTML tags like <a>, so it won't help you here where it is inside of a <script>.
• Substitute of mod_substitute is likely more suited fot that, by being able to define a regex replacement rule for the response body. Substitute "s|/tile/|/overv/tile/|"

Not sure how to deal with this problem with other proxy software, but there likely are options for this.
