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`
|
|
|
|
```yaml
|
|
homeassistant:
|
|
image: homeassistant/home-assistant
|
|
container_name: homeassistant
|
|
hostname: homeassistant
|
|
network_mode: host
|
|
environment:
|
|
- PUID=1000
|
|
- PGID=1000
|
|
volumes:
|
|
- /Volumes/homeassistant/config:/config
|
|
restart: always
|
|
labels:
|
|
- traefik.enable=false
|
|
```
|
|
|
|
Then add a new section for `nginx` adding the domains that you wish it to manage in the labels
|
|
|
|
```yaml
|
|
nginx:
|
|
image: linuxserver/nginx
|
|
container_name: nginx
|
|
environment:
|
|
- PUID=1000
|
|
- PGID=1000
|
|
volumes:
|
|
- /Volumes/nginx/config:/config
|
|
restart: always
|
|
labels:
|
|
- 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:
|
|
|
|
```nginx
|
|
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`.
