How to deploy to a subdirectory

[tholeb]

Hi. I want to deploy this app behind nginx in a subfolder (/secrets)

How can I do so ?

I already have this nginx.conf :

location /secret {
    proxy_pass http://127.0.0.1:8082;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
}

When I go to local.domain/secrets, I get redirected to /msg.

I tried setting SUPERSECRETMESSAGE_TLS_AUTO_DOMAIN: local.domain/secrets but it will handle SSL which is not what I want (I want nginx to handle this part)

Many thanks !
