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)

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
