Dcos-marathon-internal Little Dot

DCOs as the bottom support platform for running Docker, our workload is reduced a lot, but because of the large number of Docker, even with the overlay network, but IP address AH port number AH so much, we can be good.

Right, this time marathon-lb appeared, the approximate process is as follows:
1. We run Docker, hit a random port A, and tell ZK which Port B we want to have to be accessed by someone else.
2. MARATHON-LB will go to ZK to find this port B, and then as a load balancer device for others to access LB's B port directed to the actual Appdocker B port
3. Then the IP address is which to come, marathon-lb after running, will be in ZK to register, domain name Marathon-lb-internal.marathon.mesos or other domain name, good, of course, the resolution needs to put the local nslookup Server points to DCOs master. configuration json for APP Docker
