If I only mount the /data volume, I get "ERROR: /etc/letsencrypt is not mounted! Check your docker configuration."

Mounting /etc/letsencrypt instead kind of fixes the problem, the container starts.

But then I have the /data folder inside of the container.

Any hints?

Hello!

There is unfortunately no way to mount a volume to two different mount points.

I would instead like to help you with an alternative to NGINX as it's not good in environments where the upstreams use dynamic IPs like the Railway environment (both public and private) given that by default it will cache the DNS results for the upstream domain for the lifetime NGINX stays running, once the upstream changes the IP the proxy connection breaks.

Not to mention that you don't need letsencrypt given we do that for you.

So, can you start by saying what you hope to achieve with the NGINX proxy manager?

Thanks Brody,

ok, I think I have to go one step back. Thanks for pointing out that Railway already creates the certificates.

What I want to achieve: run a nginx container which serves pages with dummy content I can use in my trainings for automated tests.
The pages are showing different challenges like dropdown menus, iframes, shadow doms etc. where students can practice on.
To achieve only this, a single nginx instance is sufficient.
But I also want to provide more complex scenarios with authentication (Basic, TOTP, client certificates etc.). For this reason I think I need "something in front" of the nginx web server.

Lastly, I don't want to make the page public. Students coming from my learning platform should be authenticated with a client cookie.

Again, thanks for your advises.

Best regards, Simon

Hello,

For serving basic pages I would highly recommend Caddy, it is far more user friendly then NGINX as the Caddy config is far more approachable then NGINX's config.

As for the authorization stuff, Caddy or NGINX can do basic auth, but they aren't going to help you with other authorization methods, for that you would need to write your own code.

Thanks Brody. That helped a lot!

Happy I could help, please let me know if you have any more questions!
