> Project: Mesos
> Issue Type: Bug
> Components: docker, framework
> Affects Versions: 1.2.0
> Reporter: guanyu
>
> To prove this ,I did two tests;
> case 1：
> This is a part of configuration of marathon:
> "cmd": "python -m SimpleHTTPServer $PORT0",
> "container": {
> "type": "DOCKER",
> "volumes": [],
> "docker": {
> "image": "qihoo.cloud/cloud/x4python:1.0.0",
> "network": "BRIDGE",
> "portMappings": [
> {
> "containerPort": 2000,
> "hostPort": 0,
> "servicePort": 2000,
> "protocol": "tcp",
> "labels": {}
> }
> ],
> "privileged": false,
> "parameters": [],
> "forcePullImage": false
> }
> },
> "labels": {
> "HAPROXY_GROUP": "test"
> },
> After launch success,I tried to access haproxy port 2000,but there was no result returned,Then I checked the runtime status, The relevant information is follows:
> Marathon Endpoints: mesos20.xxx.xxx.xxx.xxx:63132
> \# docker ps
> CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
> c85ff0427da4 cloud/x4python:1.0.0 "/bin/sh -c 'pytho..." 7 minutes ago Up 7 minutes 0.0.0.0:63132->2000/tcp mesos-fc86fdb5-7a6f-4ba4-96d3-d082fcfc1236-S21.4c242985-3967-44ed-8c5d-4844ec0733c0

> tcp 0 0 0.0.0.0:63132 0.0.0.0:* LISTEN 1/python
> case 2：
> I tried to update the configuration of app, and assigned containerPort to 0, then repeated the above operations:
> "network": "BRIDGE",
> "portMappings": [
> {
> "containerPort": 0,
> "hostPort": 0,
> "servicePort": 2000,
> "protocol": "tcp",
> "labels": {}
> }
> ]
> \# docker ps
> CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
> b43e84644a8a cloud/x4python:1.0.0 "/bin/sh -c 'pytho..." About a minute ago Up About a minute 0.0.0.0:18797->18797/tcp mesos-fc86fdb5-7a6f-4ba4-96d3-d082fcfc1236-S21.1a0bfb53-1fb8-41db-98c9-6d4714587085
> Then I accessed the service by haproxy port 2000,service is ok, that's what I expected; So I think that there is a bug in the first case was triggered, Looking forward to a reply,thanks.
