Application in ACS (DCOS) on any other port except 80

Question

How can I host an application in ACS (DCOS) on any other port except 80? Can I give any other URL instead of using port number to access?

{
 "id": "/dockercloud-hello-world",
 "cmd": null,
 "cpus": 0.1,
 "mem": 128,
 "disk": 0,
 "instances": 2,
 "acceptedResourceRoles": [
   "*"
 ],
 "container": {
   "type": "DOCKER",
   "volumes": [],
   "docker": {
     "image": "dockercloud/hello-world",
     "network": "BRIDGE",
     "portMappings": [
       {
         "containerPort": 80,
         "hostPort": 0,
         "servicePort": 10000,
         "protocol": "tcp",
         "labels": {}
       }
     ],
     "privileged": false,
     "parameters": [],
     "forcePullImage": true
   }
 },

 "portDefinitions": [
   {
     "port": 10000,
     "protocol": "tcp",
     "name": "default",
     "labels": {}
   }
 ]
}

Application is available on port 4170 according to Marathon.

I am unable to access from agents fqn:portnumber

I have tried adding all the rules mentioned in the URL https://learn.microsoft.com/en-us/azure/container-service/dcos-swarm/container-service-enable-public-access — Sumanth Itha, Mar 06 '18 at 09:27

Yes, it is possible.

Firstly, you need modify hostPort value to 4170 and acceptedResourceRoles to slave_public.

Then you need open port 4170 on agent node NSG.

Then you also need open port on agent node LB.

1.Add Health probes

2.Load balancing rules

I test in my lab, it works for me. You could access my image http://shuidcagents.centralus.cloudapp.azure.com:4170/ – Shui shengbao Mar 06 '18 at 09:26

@user2547194 It seems no issue for your configuration, what is your agent ip? – Shui shengbao Mar 07 '18 at 01:55
If you try listen your container on 8080(the port is open on default)? what is the result? – Shui shengbao Mar 07 '18 at 05:13
I did not change "acceptedResourceRoles": [ "*" ] to slave_public. After change its working. Thanks for the support. can we have a differnt url like helloworld.dcos.com? – Sumanth Itha Mar 07 '18 at 07:11
Ok. can we have a different url like helloworld.dcos.com instead of accessing from the port numbers?? Will scaling of the application be a problem when we are using static ports? – Sumanth Itha Mar 07 '18 at 07:18
