JClouds GCE Metadata no credentials

Hi everyone,

I am trying to create an instance in GCE with a volume attached.


Because of I am customizing the volumes I am using instanceAPI

GoogleComputeEngineApi gce = context.unwrapApi(GoogleComputeEngineApi.class);
NewInstance instance = NewInstance.create(NAME, machineType,
networkType, uriImage);
InstanceApi instanceApi = gce.instancesInZone(ZONE);
instanceApi.create(instance);

Then I want to get the credentials of that image. As I am Strategy to
create the instance depending on the supplier, so for me it convenient to
get a Nodemetadata

nodePreBuiltId is somerhing like
https://www.googleapis.com/compute/v1/projects/soy-sound-613/zones/asia-east1-a/instances/m456-7ae

List<String> idList = new ArrayList<>();
idList.add(nodePreBuiltId);
nodes = computeService.listNodesByIds(idList);

this returns the NodeMetaData, but the credentials are null.

How can I retrieve the instance credentials in this case ?

Regards,
Ruben

Hi Ignasi,

Thanks for the idea. I agree it is the best way to solve the problem

Unfortunately the GCE API does not return the node credentials (few
provider APIs do), so you won't be able to get them.

When using the ComputeService, jclouds persists the credentials for
each node it provisions in an internal credential store, so they can
be used later to bootstrap the nodes, but since you are creating the
instances manually, the credentials are not persisted.

What you can do is to configure the credentials when you create the
instance so you know them in advance. You can do that by configuring
the instance metadata the same way the GCE ComputeService
implementation does:
https://github.com/jclouds/jclouds-labs-google/blob/master/google-compute-engine/src/main/java/org/jclouds/googlecomputeengine/compute/GoogleComputeEngineServiceAdapter.java#L139-L143

HTH!

I.
