Docker-letsencrypt-nginx-proxy-companion: configuration for domain serving static files

[uLan08]

I am currently serving static files through the nginx container and have set up a custom www.domain.com.conf file for it.

This is how it's set up

server {
    server_name www.domain.com domain.com;
    listen 80;
    proxy_buffering off;
    access_log /var/log/nginx/access.log;
    location / {
        root /app/dist/;
        try_files $uri /index.html;
    }
}

How do I configure let's encrypt to generate certificates for this domain?
I have tried running my containers using this

version: "2"
services:
  backend:
    image: backend
    environment:
      VIRTUAL_HOST: api.domain.com
      VIRTUAL_PORT: 8080
      LETSENCRYPT_HOST: api.domain.com
      LETSENCRYPT_EMAIL: [email protected]
    restart: always
  proxy:
    image: proxy-with-static
    environment: 
      LETSENCRYPT_HOST: www.domain.com,domain.com
      LETSENCRYPT_EMAIL: [email protected]
    volumes:
      - /etc/nginx/vhost.d
      - /etc/nginx/certs:/etc/nginx/certs
      - /usr/share/nginx/html
      - /var/run/docker.sock:/tmp/docker.sock:ro
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - backend
    restart: always
  letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    volumes_from:
      - proxy
    restart: always

This set up is working with the backend container but it outputs an error for www.domain.com domain.
Note that the proxy image I am using is based on jwilder/nginx-proxy I just customized it so that I can copy my static files in that container and let it use the custom .conf

Any thought on this? Is the way I am serving my static files or my configuration for it not recommended?

I was able to come up a way for this. What I did was to have the static files served by a vanilla nginx on a different container and then I added VIRTUAL_HOST and LETSENCRYPT_HOST for it in the docker-compose file and everything worked as expected.
