Re: [Openstack] Default ports for services

Couple of quick points:

a) Once the ports are fixed, we should register them with IANA as well known ports, which is the right place.[http://www.iana.org/assignments/port-numbers]

b) I was going to suggest something like a ZooKeeper, may be the service catalog serves that purpose.

c) Also, on the port numbers, I assume they will manifest as universal constants and/or a configuration file in a universally (or intergalactically ;o)) known place.

Cheers

Where's the best place to keep track of default ports for services to avoid conflicts? A wiki page on wiki.openstack.org?

We had a discussion while working on Keystone about default ports for OpenStack services (https://github.com/rackspace/keystone/issues/31). We want OpenStack to work 'out-of-the-box' without built-in port conflicts, so we should coordinate which ports new services start on.

At a minimum, we need that for Keystone as it isn't discoverable. Other services can be discovered using the service catalog that Keystone returns as part of an auth request (Sample response below at end of email).

Here's a list of ports we talked about on https://github.com/rackspace/keystone/issues/31

80: Swift proxy server (swift/etc/proxy-server.conf-sample)

6000: Swift object server

6001: Swift container server

6002: Swift account server

6080: Nova VNC proxy

8001: Nova direct API

8080: Swift proxy server (swift/bin/swift-proxy-server)

3306: MySQL

5672: AMPQ (RabbitMQ)

9292: Glance API

9191: Glance Registry

5900...590?: qemu-system for VNC

We've moved Keystone to 5000/5001 (for Service and Admin API, respectively).

Sample Response with service catalog:

{

  "auth":{

   "token":{

   "id":"asdasdasd-adsasdads-asdasdasd-adsadsasd",

   "expires":"2010-11-01T03:32:15-05:00"

   },

   "serviceCatalog":{

   "nova":[

   {

   "region":"NorthAmerica",

   "publicURL":"https://service1-public:9000/v1/blah-blah",

   "internalURL":"https://service1-internal:9001/v1/blah-blah"

   },

   {

   "region":"Europe",

   "publicURL":"https://service1-public-eu/v1/blah-blah",

   "internalURL":"https://service1-internal-eu/v1/blah-blah"

   }

   ],

   "swift":[

   {

   "region":"regionOne",

   "publicURL":"https://service2-public-dat/v1/blah-blah"

   }

   ]

   }

  }

}
