How do I run 2 environments simultaneously?

[millisami]

First I fired up those two instances.

docker run -d -p 8080:8080 -p 172.17.42.1:53:53/udp --name skydns crosbymichael/skydns -nameserver 8.8.8.8:53 -domain docker

docker run -d -v /var/run/docker.sock:/docker.sock --name skydock crosbymichael/skydock -ttl 30 -environment dev -s /docker.sock -domain docker -name skydns

And this setup is working as expected.

Now I want to spawn another production environment. This time I only fired another skydock container with the env production as follows.

docker run -d -v /var/run/docker.sock:/docker.sock --name skydock-prod crosbymichael/skydock -ttl 30 -environment prod -s /docker.sock -domain docker -name skydns

Querying the api doesn't show the production skydoc.

curl $(docker-ip):8080/skydns/services/

And now I am wondering on how to setup the production version of skydock.

Do I have to run in separate docker-host?
If I fire up in the same docker host, in which DNS url entry will the new containers be available?
Do I have to pass some flags/variables when I fire new containers to be available in the production env?

Any pointers?
