AWS cloud volume relationships

IMD · January 7, 2018, 10:03pm

hello I am stuck on some proviosing and relationship building around amazon ebs and instances.
using rails console I can simply
vm = Vm.find_by_name(“VMNAME”)
vm.cloud_volumes
vol = vm.cloud_volumes.first
vol.create_volume_snapshot(name: “idtest”)

and this all works fine.
however using automate I can not seem to get this to work.
I have tried all kinds of different ways to load the vm object and not only is the cloud_volumes method not available I can’t seem to output any actual volume info.

Any help is appreciated.

thanks

Hello, for Automate, there is a special wrapper object, that needs to have the relation and action exposed.

Here:

github.com

Ladas/manageiq-automation_engine/blob/75c98a205b3fda7843119505bbdb7f4972b8dcae/lib/miq_automation_engine/service_models/miq_ae_service_manageiq-providers-cloud_manager-vm.rb#L13


  expose :availability_zone, :association => true
  expose :flavor,            :association => true
  expose :cloud_network,     :association => true
  expose :cloud_subnet,      :association => true
  expose :network_ports,     :association => true
  expose :network_routers,   :association => true
  expose :cloud_subnets,     :association => true
  expose :floating_ip,       :association => true
  expose :floating_ips,      :association => true
  expose :security_groups,   :association => true
  expose :key_pairs,         :association => true
end
end

we need:
expose :cloud_volumes, :association => true

And here

github.com

Ladas/manageiq-automation_engine/blob/170ecc72c4ffac1f0a576ad37d1d6a8702bcae66/lib/miq_automation_engine/service_models/miq_ae_service_cloud_volume.rb#L14


  include MiqAeServiceEmsOperationsMixin


  expose :ext_management_system,  :association => true
  expose :availability_zone,      :association => true
  expose :cloud_tenant,           :association => true
  expose :base_snapshot,          :association => true
  expose :cloud_volume_backups,   :association => true
  expose :cloud_volume_snapshots, :association => true
  expose :attachments,            :association => true
  expose :attach_volume,          :override_return => nil
  expose :detach_volume,          :override_return => nil
end
end

so adding line:
expose :create_volume_snapshot, :override_return => nil

after restarting the appliance, it should work also in automate (just the find_by_name is different syntax)

Can you fill a GitHub issue or Bugzilla on Automate missing these as exposed? Or you can send even a Pull Request with the changes, it they’ll work.

Thanks. I made changes locally and verified everything works as it should. This is great!
