specify disk size while creating instance in openstack

[Subhadip Bagui <i....@gmail.com>]

Hi,

I'm using the below code in openstack for create instance which will use
openstack flavor list to get the hardware details. Is there any was to pass
the *disk size explicitly* using computeService API ? Like I can do the
same from openstack console and a cinder volume will get attached in
instance.

    ComputeServiceContext computeContext =
ContextBuilder.newBuilder(credentials.getProviderName())
           .endpoint(credentials.getResourceEndPoint())
           .credentials(cred, passwd)
           .modules(ImmutableSet.<Module> of(new SshjSshClientModule()))
           .overrides(openStackPropeties)
           .buildView(ComputeServiceContext.class);

templateBuilder.imageId(instance.getImageId());
           templateBuilder.hardwareId(instance.getInstanceType());
           options.as(NovaTemplateOptions.class).nodeNames(
                   new ArrayList<String>(Arrays.asList(instance
                           .getInstanceName())));
           options.as(NovaTemplateOptions.class).networks(
                   instance.getNetworkType());
           templateBuilder.locationId("RegionOne");
           build = templateBuilder.build();

Set<? extends NodeMetadata> nodeMetadatas =
computeService.createNodesInGroup("securitygroup.name",
                   instanceCount, build);

I have tried giving templateBuilder.minDisk(5); but this is not taking the
required volume.

Please let me know is there any other way to do this.
