Issue with inserting multiple metadata key/values while create a new instance

[Vikram Saggu]

Hi all,

Using PHP with Google Service Account library to create instance's.

Issue is with setting up multiple metadata key/values.

While giving up multiple metadata key/values on creating a new instance, it is only taking single key/value instead.

Here is my code.

/// META-DATA
    $googleMetadataItemsObj = new Google_Service_Compute_MetadataItems();
    $googleMetadataItemsObj->setKey('fname','lname');
    $googleMetadataItemsObj->setValue('abc','def');   
   
    $googleMetadataObj = new Google_Service_Compute_Metadata();
    $googleMetadataObj->setKind('compute#metadata');
    $googleMetadataObj->setItems(array($googleMetadataItemsObj));
/// META-DATA

    $new_instance = new Google_Service_Compute_Instance();
    $new_instance->setName($instancename);
    $new_instance->setKind('compute#operation');
    $new_instance->setMachineType($machineType);
    $new_instance->setDisks(array($googleAttachDiskObj));
    $new_instance->setNetworkInterfaces(array($googleNetworkInterfaceObj));
    $new_instance->setMetadata($googleMetadataObj);
    $new_instance->setServiceAccounts($googleServiceAccountObj);
    $insertInstance = $computeService->instances->insert(DEFAULT_PROJECT,$zone, $new_instance);

Hello Vikram,

Is it possible to do a get on the key/value and check for the output?

I was able to find this discussion that might shed some light.

I hope this helps.

Sincerely,

George

Hello George,

The discussion you referred is also setting up single key/value for the metadata, which i am able to do it. My problem is while setting up multiple key/values in metadata. Issue is with preparing array i think which is not happening. I tried my best alternate ways but still fails to insert multiple metadata key/values.

I've replied to your referred discussion, mentioning my problem. If you could see it again and try to sort if possible.

Thank you.

Hello Vikram,

Thank you for providing the REST output on the other discussion. As only one key and one value should pass at a time, see this github for more information.

I hope this helps.

Sincerely,

George

Hello George,

I figured it out by doing the following way for adding multiple key/values in Metadata.

/// META-DATA
    $googleMetadataItemsObj = new Google_Service_Compute_MetadataItems();

    $googleMetadataItemsObj=array(array("key"=>'firstkey',"value"=>'firstvalue'),array("key"=>'secondkey',"value"=>'secondvalue'));

   
    $googleMetadataObj = new Google_Service_Compute_Metadata();
    $googleMetadataObj->setKind('compute#metadata');

    $googleMetadataObj->setItems($googleMetadataItemsObj);
/// META-DATA
