[google compute] improve MachineType (size) coverage of GCE API #396

wants to merge 1 commit into from


Copy link

@erjohnso erjohnso commented Nov 20, 2014

Minor improvements to GCE Machine Types (sizes in libcloud parlance) to match GCE API.

  • added missing resource attributes to GCENodeSize
  • hiding some parameters from extra since they've been removed (namely imageSpaceGb)
  • minor change to the disk.size value based on presence/absence of attributes

Updated test fixture and test.

@erjohnso so we cannot change the disk_size through an argument ?

@Runseb - no, you can't change parameters on a GCE MachineType. These are analogous to AWS "sizes" like x2.large, c2.medium (or whatever they are). They are static descriptions of the "size" of VM.

Google has made a change to the API since this code was originally contributed and now the most appropriate way to report a MachineType's disk size is to use maximumPersistentDisksSizeGb over the now rarely seen imageSpaceGb attribute.
