Docker Orchestration

Using network services and load balancing

Mesosphere provides a number of networking services that make orchestration easier. These services provide service discovery and load balancing for running applications.

Discovering services with DNS

Every service that is created is assigned a hostname in Mesos DNS. The entries are service-name.marathon.mesos, where service-name is the name of the service in the id field. The following snippet is from a service with id set to simple-nginx. Mesos DNS would create a record named simple-nginx.marathon.mesos:

  "id" : "simple-nginx", 
  ... 
} 

Because the services are translated directly into DNS hostnames, there are a few restrictions, as follows:
