我想在谷歌计算引擎上启动/恢复和停止/暂停实例,但它提供“java.lang.UnsupportedOperationException”。有任何替代方式 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:

  

暂停节点(节点ID)

     
    

线程“main”中的异常java.lang.UnsupportedOperationException:GCE不支持suspend

您可以从API停止实例。

POST https://www.googleapis.com/compute/v1/projects/<project>/zones/<zone>/instances/<instance>/stop

其中:

    URL中的
  • 项目 是项目ID。
  • URL中的
  • 区域是请求的区域名称。
  • URL中的
  • 实例是要停止的实例的名称。

这里是docs

便携式jclouds ComputeService不直接支持它,但是从ComputeServiceContext可以获得GoogleComputeEngineApi和InstanceApi,并使用其中的启动/停止方法。

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