Docker private network individual host access

Howdy,

We’re trying to bring up a DO docker host with 200 containers for testing our agent application and we cannot figure the network part. Let me explain:

• We are developing an application that is agent-based. An agent is installed on a host and it self-registers with a server to initiate on-going communication.
• The server then communicates with each host running an agent and send commands.
• The agents communicate back to the server with a message q
• Each agent needs its own ip and standard ports with which the server sends commands

I think we can do this with docker Host networking. My thoughts are (forgive my networking ignorance):

• we give the DO docker host an internal class-b like 172.99.x.x
• we launch 200+ agent containers in host mode and assign static (or dhcp) addresses to each from the class-b
• the server is on a remote host that vpns into the DO Docker Host
• hopefully the server can now “see” the class-b and all of its containers and the containers can communicate with the remote server

I know this is broken… where am i falling down.

Thanks!
