Subject RE: assign a port on vm create?
Date Fri, 05 Dec 2014 14:30:01 GMT
Zack,

First, thanks for trying to help ..

and yes, it is the 'provide a port uuid' on boot I am having trouble with
from JClouds.

Your listed steps are exactly  what I did prior to this,( including grazing
thru javadocs).

I see that this can be done from Openstack/neutron command line but the
jclouds Nova api

options (org.jclouds.openstack.nova.v2_0.compute.options.NovaTemplateOptions
)

doesn't seem to allow specifying the port uuid .. 

I include code here  .. What am I missing?

.

.

.

              Properties properties = NovaApiMetadata.defaultProperties();

              properties.setProperty(TIMEOUT_SCRIPT_COMPLETE, 6000 * 1000 +
""); //100 minutes

              logit("<"+thisClass+":> " + "         get context: " );

              context = ContextBuilder.newBuilder("openstack-nova")

                           .endpoint("http://"+controllerIP+":5000/v2.0/")

                           .credentials("demo:demo", "demo")

                           .overrides(properties) //set timeout here

                           .modules(ImmutableSet.of(new
SshjSshClientModule(),new SLF4JLoggingModule())) 

                           .buildView(ComputeServiceContext.class);

              logit("<"+thisClass+":> " + "        context: "
+context.toString());

              compute = context.getComputeService();

              templateOptions = compute.templateOptions();

//            In OpenStack Neutron, many times one prefers to rely on DHCP
to have instances (VMs) have IP addresses assigned, mostly for simplicity.

//            But there are cases where one would like to reserve a few IPs
statically to be used by certain VMs.

//            Well, it is possible to achieve this by manually creating
ports inside the tenant network and attach them to an instance. 

 

 

 

              portapi = neutronApi.getPortApi("RegionOne");

 

 

              List<Port> ports = portapi.list().concat().toList();

              Port port = null;

              for (int ii = 0; ii< ports.size(); ii++) {

                     port = ports.get(ii);

//                   System.out.println("<"+thisClass+":> " + "  PORT =
>>>>>" + port.getId());

                     if (port.getName().contains("infra"))

                           portapi.delete(port.getId());//cleanup old ports

              }

 

              portapi = neutronApi.getPortApi("RegionOne");

 

 

              List<Port> ports = portapi.list().concat().toList();

              Port port = null;

              for (int ii = 0; ii< ports.size(); ii++) {

                     port = ports.get(ii);

//                   System.out.println("<"+thisClass+":> " + "  PORT =

Here is my suggestion.
Create a neutron network.
Create a subnet (you will be allocating fixed IPs from that subnet's CIDR
range).
Create 8 ports on that subnet.
These ports should specify fixed ips.
These fixed ips should provide the subnet id and a fixed ip that is within
the subnet range.

Then:
For each VM that you boot, you can provide a port uuid (when you boot with
the nova API)
http://jclouds.apache.org/reference/javadoc/1.8.x/org/jclouds/openstack/nova
/v2_0/domain/Network.Builder.html#portUuid(java.lang.String)
(It seems this is the part that you might be having trouble with).

Let me know if this works or if you are having issues getting it to work.

-Zack

Thx Dan for the details. 

I think it is a specific question for Neutron support and I can't help you
immediately on it. Could you please file an issue on jira reporting pretty
much the same description so that we as community don't forget it again? 

thanks, 
Andrea

Oh .. of course ..
thought that might be  a generic question.

I use JClouds 1.8.0 (I notice that neutron is broken in 1.8.1 or would have
upgraded).
I am using Openstack icehouse on a  local endpoint collocated with my
VM installations with Chef-solo installed on my centos 6.5 image.
I need to instantiate and provision 8 VMs which need to perform nfs mounts
against each other during their provisioning and issue commands over ssh
between them
when all are up and operational.
I have looked into everything I can find scraps of in the ether to provide
static
ips  so this can happen but they all seem to dead end for one reason or
another, usually
resulting in silence in fact when someone else has the same general
question.
 Anyway wrapping an ip in a port using the neutron api looked promising but
need to get the
VMs to use the port to see if that would even work.

thx

Hi Dan,

could you please clarify which jclouds version are you using?
which provider/api are you consuming?
Is it a public openstack (I guess) endpoint or an on-premise installation?
If the latter what services can you use?

I think those are useful preliminary questions to get the context of your
use case.

Thanks,
Andrea
