error inserting instance with gcloud api gem

Question

trying to launch an instance in Google Cloud using google-api-client 0.9.2 So I'm running:

compute.insert_instance(project, zone, instance_opts)

Where instance_opts is:

---
machineType: https://www.googleapis.com/compute/v1/projects/openshift-gce-devel/zones/us-central1-a/machineTypes/n1-standard-1
disks:
- initializeParams:
    sourceImage: https://www.googleapis.com/compute/v1/projects/myproject/global/images/myimage
  type: SCRATCH
networkInterfaces:
- network: projects/myproject/global/networks/default
  accessConfigs:
  - name: external
name: mytest

But I'm getting an error from server:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "required",
    "message": "Required field 'resource.name' not specified"
   }
  ],
  "code": 400,
  "message": "Required field 'resource.name' not specified"
 }
}

I'm getting exact same issue even if I make instance_opts only:

{"name": "mytest"}

I get an error for unknown field "resource" or "resource.name" if I try to set these in instance_opts. Setting name of disk also doesn't help. So I'm wondering what the issue could be.

Answer 1

Huh, might be stupid but I couldn't understand it for a good time that I actually have to create an Instance object and use it for the call.

io = Google::Apis::ComputeV1::Instance.new(instance_opts)
compute.insert_instance(project, zone, io)

But with one more detail. Hash should be :machine_type instead of "machineType". That's the same for all hash keys.
