Hi,  
I've just created an nginx container for website with rule Host. It work well.

I would like to change it to works with HostRegexp for multidomain requests.  
I want to have one website for serveral subdomains but regexp doesn't work.

Domains  
[name.subdomain.domain.com](http://name.subdomain.domain.com)  
[name.subdomain2.domain.com](http://name.subdomain2.domain.com)  
[name.domain.com](http://name.domain.com)

I try tu use this rule in my docker-compose file:  
labels:  
- "traefik.enable=true"  
- "traefik.http.routers.web.rule=HostRegexp(`name(.subdomain|subdomain2|.)domain.com`)"

or

labels:  
- "traefik.enable=true"  
- "traefik.http.routers.web.rule=HostRegexp(`name.(subdomain|subdomain2|).domain.com`)"

Both rules are not working. How to do this well?

Use "or":

```auto
.rule=Host(`example.com`) || Host(`sub.abc.com`)

```
