should consul have any port?

[bravowhale-jenkins]

i build consul in docker ,and run it on marathon, i'm a little confused ,should consul expose some port like mesos-dns , and should i change the /etc/resolve.conf ,point the nameserver to consul's IP ,
and i see consul-temples the command like this

$ consul-template
-consul 127.0.0.1:8500
-template "/tmp/template.ctmpl:/var/www/nginx.conf:service nginx restart"
-retry 30s
-once

is the port 8500 belong to consul ?

Yes, port 8500 belongs to Consul's REST API. It also optionally exposes a DNS listener in port 8600. You can use that to do things like DNS SRV requests to get host/port info for deployed services.

If you want to use Consul DNS, then you should deploy dnsmasq, point /etc/resolv.conf to the dnsmasq ip / port, and then set up dnsmasq to use consul's port 8600 to route all service.consul. domains to that DNS server, leaving all of the other DNS requests alone.
