Serve moodist docker as a subfolder through Nginx proxy

[NachoParra]

Hi,

I found this project and I love it, many thanks.

I have deployed it with the docker image and I can access the webpage of the docker directly, but I want to serve it through an nginx proxy as a subfolder, smething like https://subdomain.domain.com/moodist/.

I have tried adding a rewrite rule on the nginx configuration file
rewrite /moodist(.*) $1 break;
But it's not working, as expected.

Also I tried to add a environment variable on the docker container like I did with other docker images
- "SUBFOLDER=/webtop/"
But it's also not working.

My first question will be to ask if moodist can be served like this, and if it can be, can you please update the readme to explain how?

Thanks!!
