Rancher host based routing

how can i use wildcards when adding host based routing ?
When i add *.domain.com -> hdr_end(host) -i .domain.com to the haproxy config when adding a new load balancer , it stays in initializing

I guess the documentation is unclear, but the part you put in is just “*.domain.com”… The rest is the resultibg rule that gets put into the balancer.

Thanks for your reply but i don’t understand where to put this configuration in the GUI , i want to route *.domain.com to the appropriate container with the same hostname
