How can I assign random ports to a cni network and read these back from 
srv. What is the equivalent of portDefinitions at network/host for 
network/container?

If I change a task from: 

  "networks": [ 
    { "mode": "host" }
  ],
  "portDefinitions": [
    {"port": 0, "name": "health",  "protocol": "tcp"},
        {"port": 0, "name": "metrics",  "protocol": "tcp"}
  ],

To: 

  "networks": [ 
    { "mode": "container", "name": "cni-storage" }
  ],
  "portDefinitions": [
    {"port": 0, "name": "health",  "protocol": "tcp"},
        {"port": 0, "name": "metrics",  "protocol": "tcp"}
  ],


I am getting this error:

W0804 23:18:12.942282 3421440 health_checker.cpp:273] HTTP health check

But when I disable the health check, and enter the network namespace of 
the running task. This localhost check is working [@ 
c59ea592-322f-4bfc-8981-21215904da58]# curl http://localhost:52684/test 
<html><body><h1>200 OK</h1> Service ready.
</body></html>

What am I doing wrong?
