我想在Google計算引擎上啓動/恢復並停止/掛起實例,但它給出了「java.lang.UnsupportedOperationException」。是否存在任何替代方法 來執行這些操作?在Google計算引擎上啓動和停止實例
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;
}
}
}
輸出:
懸浮節點在螺紋(節點ID)
異常 「主」 java.lang.UnsupportedOperationException:掛起不是由GCE
支持at org.jclouds.googlecomputeengine.compute.GoogleComputeEngineServiceAdapter.suspendNode(GoogleComputeEngineServ iceAdapter.java:251)
