Server resource advanced block_mapping - volume boot support.

[hjensas]

What would you like to see implemented?

I would like ORC to support creating Server resources with boot from volume and advanced block_device_mapping.

Example:

block_device_mapping=[
    {
       'uuid': IMAGE_ID,
       'boot_index': 1,
       'source_type': 'image',
       'destination_type': 'volume',
       'device_type': 'disk',
       'volume_size': 20,
       'delete_on_termination': True,
    },
    {
       'uuid': BLANK_IMG_ID,
       'boot_index': 0,
       'source_type': 'image',
       'destination_type': 'volume',
       'device_type': 'cdrom',
       'disk_bus': 'scsi',
       'volume_size': 5,
       'delete_on_termination': True,
    }
]

Additional information

Background - in the future I would like to see if replacing or have k-orc as an option to Openstack Heat in https://github.com/openstack-k8s-operators/hotstack. It uses advanced block device mapping to enable sushy-emulator RedFish virtual-media boot simulation.

Definitely something that is on the roadmap.
