我希望能够在谷歌计算引擎上开始 / 恢复和停止 / 暂停实例,但它会出现“java.lang.UnsupportedOperationException”。是否有其他替代方法可以执行这些操作?请注意保留 HTML 标记。
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)
异常线程“main”java.lang.UnsupportedOperationException:GCE不支持暂停
