如何在openstack创建实例中指定磁盘大小

Question

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 ?

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);

TemplateBuilder has a minDisk(double gigabytes) option that can be used to supply minimum disk size.
