HTTPS with Let's Encrypt for Nginx

[AnWaKZ]

Can I configure Restreamer (running in Docker) to use the Let's Encrypt certificates that are already issued for Nginx on the host, instead of generating separate ones?
For example, I already have these files:
/var/lib/letsencrypt/live/domainname/fullchain.pem /var/lib/letsencrypt/live/domainname/privkey.pem /var/lib/letsencrypt/live/domainname/cert.pem /var/lib/letsencrypt/live/domainname/chain.pem

Hello ! I think that you can do this just by mounting the correct dir on your container.

services:
  restreamer:
    image: datarhei/restreamer
    container_name: restreamer
    ports:
      - "8080:8080"
      - "8443:8443"
    volumes:
      - /var/lib/letsencrypt/live/domainname:/certs:ro #adapt here 

Does this answer to your question ?

I did the opposite away, nginx uses the letsencrypt ssl certificates generated by restreamer:

services:
    nginx:
        container_name: nginx
        image: nginx
        build:
            context: .
            args:
                NGINX_DOMAIN: ${NGINX_DOMAIN}
        ports:
            - "80:80"
            - "443:443"
        volumes:
            - "/opt/restreamer/config/cert/certificates/acme-v02.api.letsencrypt.org-directory/${NGINX_DOMAIN}:/opt/nginx/cert/${NGINX_DOMAIN}"
            - "/var/log/nginx/${NGINX_DOMAIN}:/var/log/nginx"
        restart: always
        networks:
            - nginx
            - restreamer

    restreamer:
	...

But need to restart nginx periodically (auto) to pick updated certificates.

The simple way is installing Nginx Proxy Manager, and use the desired URL, and add the SSL using that.
