我想在google上启动/恢复和停止/挂起实例,但是它为"java.lang.UnsupportedOperationException".Is提供了执行这些操作的其他方法吗?
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:

在可移植的jclouds中不直接支持它,但是可以从ComputeServiceContext中获得GoogleComputeEngineApi和InstanceApi,并在其中使用start/stop方法。
FYI,有一个正在进行的修补程序可以在ComputeService:https://github.com/jclouds/jclouds-labs-google/pull/141中添加对开始/停止操作的支持。

您可以从API中停止一个实例。
