Base path to reverse proxy

[fana13]

It will be great if we could specify a base path through the docker environment, like this : -e BASE_PATH=/speedtest

If you search the issues, there are many discussions on reverse proxies setup, Traefik etc.

[fana13]

I've read many discusssions about this, but not really that issue.
It's about subfolder nginx for reverse proxy.
APP_URL in .env it's not for that, right ?

[alexdelprete]

the app is listening on 80 and 443, you should be able to address this with NGINX without requiring modifications.

What exactly are you trying to achieve?

[fana13]

I try to have https://myowndomain/speedtracker

[alexdelprete]

With Traefik I can do that using a prefix after the domain. I guess it's doable also with NGINX if that's what you use, you don't need basepath on the app.

@alexdelprete how you do this in Traefik?

When using with nginx /speedtracker path shows 404 and docker logs show this:
"GET /speedtracker/ HTTP/1.0" 404 6603 "

If I put this to nginx (basically app sees / while reverse proxy/user uses /speedtracker/)
rewrite /speedtracker/(.*) /$1 break;

It will try to redirect to mydomain.com/admin after that, which is also incorrect behaviour as it should redirect to mydomain.com/speedtracker/admin.

With older speedtest-tracker using environment key APP_URL=/speedtracker worked perfectly.

I also tried to use same env config with this one without success. Same thing when trying to use APP_URL=mydomain.com/speedtracker.

[fana13]

Same for me, it doesn't work.
For example, with the older henrywhitaker's repo, this nginx configuration work like a charm.
@alexdelprete could you unclose this issue, it seem real

[alexdelprete]

how you do this in Traefik?

[alexdelprete]

Same for me, it doesn't work.

what exactly doesn't work? Speedtest-Tracker is not a proxy, nor a webserver, it's a webapp.

you can say something doesn't work when its documentation describes a feature, a configuration, and that doesn't work. this is not the case. your expectations about an app is not a bug.

this webapp is listening on http/https ports, no path/subpaths, but on root. it's up to your reverse proxy to be configured like you want it to behave, in order to proxy correctly this webapp on root path. On Traefik StripPrefix can be used, on NGINX I have no idea because I never used it. Check NGINX documentation on how to achieve this and don't blame it on the webapp.

Furthermore, I'm not the maintainer/dev, that would be @alexjustesen and he already closed the case because it's not a bug, it's something the reverse proxy has to manage.

@alexdelprete This doesn't work, same redirect problem with traefik when using

It tries to redirect to mydomain/admin when it should be redirecting mydomain/speedtest-tracker/admin

Base url has to be programmed into application, middleware/reverse proxy cannot fix this as far as I know.

If you have working configuration, feel free to share.

I don't tag it as a bug, tag was FEATURE and i think it's a real feature.
So if you can't have any idea because you never use it, why did you close this ?
I have checked NGINX documentation, i have a lot of app in my nginx configuration.
I gave you an example with the older repo, which have added a APP_PATH or PATH_URL in the .env, that's why i asked if this feature will be implemented, nothing more

Sorry, I tought you opened it as an issue, my bad.

I'm not the maintainer, you are confusing names.

I gave you an example with the older repo

This is not the old project, it's a new one. You can achieve what you want if you configure properly your reverse proxy, if your reverse proxy doesn't allow to do it, change proxy.

Quote from traefik docs:

Use a StripPrefix middleware if your backend listens on the root path (/) but should be exposed on a specific prefix.

That is exactly what you're trying to achieve, that's the use case.

Feel free to look for working configs in Traefik community forums, there are a lot of threads, here's one: https://community.traefik.io/t/traefik-v2-6-pathprefix-wont-work/13398/2
