Examples with TemplateService org.ovirt.engine.sdk4.services.TemplateService used on opensource projects

Example 1 with TemplateService

use of org.ovirt.engine.sdk4.services.TemplateService in project ovirt-engine-sdk-java by oVirt.

the class AddVmFromTemplateVersion method main.

public static void main(String[] args) throws Exception {
    // Create the connection to the server:
    Connection connection = connection().url("https://engine40.example.com/ovirt-engine/api").user("admin@internal").password("redhat123").trustStoreFile("truststore.jks").build();
    // Get the reference to the root of the tree of services:
    SystemService systemService = connection.systemService();
    // Get the reference to the service that manages the storage domains:
    StorageDomainsService storageDomainsService = systemService.storageDomainsService();
    // Find the storage domain we want to be used for virtual machine disks:
    StorageDomain storageDomain = storageDomainsService.list().search("name=mydata").send().storageDomains().get(0);
    // Get the reference to the service that manages the templates:
    TemplatesService templatesService = systemService.templatesService();
    // When a template has multiple versions they all have the same name, so we need to explicitly find the one that
    // has the version name or version number that we want to use. In this case we want to use version 3 of the
    // template.
    List<Template> templates = templatesService.list().search("name=mytemplate").send().templates();
    String templateId = null;
    for (Template template : templates) {

            templateId = template.id();
            break;
        }
    }
    // Find the template disk we want be created on specific storage domain
    // for our virtual machine:
    TemplateService templateService = templatesService.templateService(templateId);
    List<DiskAttachment> diskAttachments = connection.followLink(templateService.get().send().template().diskAttachments());
    Disk disk = diskAttachments.get(0).disk();
    // Get the reference to the service that manages the virtual machines:
    VmsService vmsService = connection.systemService().vmsService();
    // Add a new virtual machine explicitly indicating the identifier of the template version that we want to use:
    vmsService.add().vm(vm().name("myvm").cluster(cluster().name("mycluster")).template(template().id(templateId)).diskAttachments(diskAttachment().disk(disk().id(disk.id()).format(DiskFormat.COW).storageDomains(storageDomain().id(storageDomain.id()))))).send();
    // Close the connection to the server:
    connection.close();
