How to use Nginx under Traefik

I’ve been enjoying Traefik for its auto-discovery of containers. The only problem is that for a couple containers such as Plex and HomeAssistant I have host networking enabled. This usually results in Traefik failing to forward the traffic properly.

Having more fine grained control is exactly what Nginx is for! I don’t want to switch my whole setup to Nginx since that would be a lot of configuration files for every docker container. But I think having configuration files for containers that use host networking is manageable.

In your docker-compose file first make sure that Traefik is disabled for containers that use host networking by adding the label traefik.enable=false

    image: homeassistant/home-assistant
    container_name: homeassistant
    hostname: homeassistant
    network_mode: host
      - PUID=1000
      - PGID=1000
      - /Volumes/homeassistant/config:/config
    restart: always
      - traefik.enable=false

Then add a new section for nginx adding the domains that you wish it to manage in the labels

 image: linuxserver/nginx
 container_name: nginx
   - PUID=1000
   - PGID=1000
   - /Volumes/nginx/config:/config
 restart: always
   - traefik.http.routers.my-container.rule=Host(`plex.example.com`,`homeassistant.example.com`)

Now on the host system add the configuration files for nginx to consume. Example:

server {
    listen 80;
    listen [::]:80;

    server_name plex.example.com;

    location / {
        proxy_pass http://homelanip:32400;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;

Similarly add a configuration file for homeassistant or any other service you have.

Now for this example, the subdomains plex.example.com and homeassistant.example.com are managed by Nginx.

To finish it off, docker-compose start nginx.
