I looked through seemingly related questions but haven't found much of an actual answer yet. I downloaded the CDH quickstart docker and have been trying to deploy it such that the various common Hadoop browser ports are exposed through the localhost browser, namely Hue. The docker runs successfully. I get a prompt inside the docker and can run hadoop and hive from the command line, but http://localhost:7180 and http://localhost:8888 never reach anything. Any help appreciated. Here's what I've tried so far:
docker run --privileged=true --hostname=quickstart.cloudera -p 7180 -p 8888 -t -i 4239cd2958c6 /usr/bin/docker-quickstart
docker run --privileged=true --hostname=quickstart.cloudera -p 7180:7180 -p 8888:8888 -t -i 4239cd2958c6 /usr/bin/docker-quickstart
Neither of those worked. What am I doing wrong?
EDIT: Hmmm, okay, admittedly, if I use the port that docker is arbitrarily mapping to (32770, 32771, 32772) it works. So that's good news, but why doesn't the 7180:7180 syntax (shown above) map it through to the same port? I can see that docker thinks the mapping is working properly, but the browser fails to produce a page at that port. In fact, doing so breaks the arbitary port (around 32772 and 32773), even though it doesn't map the intended ports (7180, 8888). So it works if I don't try to remap the ports. Any idea why?

OS X El Capitan. Does that mean I need to run the docker using some different command? What do I need to do differently?
It is essentially working for me actually. I can get Hue through the browser for example. The one thing I can't get it it do is map the ports to the *expected* ports, preserving 7180 for example. Instead I have to use whatever crazy port number the docker arbitrarily chooses (something in the 32000s).
