How launch many instances at once?

[pditommaso]

The snippet at this link shows how launch a compute instance, however I was unable to find in the API a way to specify the number of instances to run.

Is that possible or it is needed to invoke the create operation as many times as the number of instances to launch ?

If you create an InstanceGroup you can size up/down using resize function with code like this:

Compute.InstanceGroupManagers.Resize resizeRequest = computeService.instanceGroupManagers().resize(APPLICATION_NAME, COMPUTE_ZONE, COMPUTE_GROUP, myNumberOfDesiredInstances);
resizeRequest.execute();

I see. However instance groups and templates are only exposed via com.google.api.services.compute.Compute and not (yet?) implemented by the com.google.cloud.compute.Compute interface.

Quite confusing.

I'm still struggling with this problem. Stating version 0.8.1-alpha it looks that there's no API to handle Instance groups and Instance templates. Could you please confirm that and if there's any plan to support them?

Tried version 0.10.0-alpha. Still no solution to launch more than one instance in a single request.

We are going to be doing some work on the Compute client over the next several months. Unfortunately we won't be addressing anything in the short term, though.
