我想在Google计算引擎上启动/恢复和停止/挂起实例,但是它给出了“java.lang.UnsupportedOperationException”。是否有其他替代方法
执行这些操作?

public class Example {

     public static void main(String[] args)
     {
      String provider = "google-compute-engine";
      String identity = "****@developer.gserviceaccount.com";
      String credential = "path to private key";
      String groupName = "newgroup";
      credential = getCredentialFromJsonKeyFile(credential);
      Iterable<Module> modules = ImmutableSet.<Module> of(
              new SshjSshClientModule(),
              new SLF4JLoggingModule(),
              new EnterpriseConfigurationModule());
      ContextBuilder builder = ContextBuilder.newBuilder(provider)
              .credentials(identity, credential)
              .modules(modules);
      ComputeService compute=builder.buildView(ComputeServiceContext.class).getComputeService();

      compute.suspendNode("Instance id");
      //compute.suspendNodesMatching(Predicates.<NodeMetadata> and(inGroup(groupName)));
      System.out.println("suspended");
      compute.getContext().close();
}

   private static String getCredentialFromJsonKeyFile(String filename) {
      try {
         String fileContents = Files.toString(new File(filename), UTF_8);
         Supplier<Credentials> credentialSupplier = new GoogleCredentialsFromJson(fileContents);
         String credential = credentialSupplier.get().credential;
         return credential;
      } catch (IOException e) {
         System.err.println("Exception reading private key from '%s': " + filename);
         e.printStackTrace();
         System.exit(1);
         return null;
      }
   }
}

输出:

挂起的节点(节点ID)


线程“主”中的异常java.lang.UnsupportedOperationException:GCE不支持暂停

最佳答案

便携式jclouds ComputeService不直接支持它,但是可以从ComputeServiceContext中获取GoogleComputeEngineApi和InstanceApi,并在其中使用start / stop方法。

仅供参考,有一个正在进行中的补丁可在ComputeService中添加对启动/停止操作的支持:https://github.com/jclouds/jclouds-labs-google/pull/141
