Description Julia Kreger 2018-07-30 13:45:21 UTC
Description of problem:

Upstream ironic has merged basic support (in Rocky) for an additional deployment interface, primarily geared at large scale operators and the scientific community as their use cases of rapid turnaround and disk-less nodes, since disk are often viewed as a additional possible failure point at that scale and operating class.

This interface does have a number of limitations[1] from standard interface usage, but we should test and support basic usage for operators that seek ephemeral nodes to be deployed.

Comment 1 Julia Kreger 2018-08-16 13:07:55 UTC
Discussed with Ramon and this will be treated as a TechPreview item.

Comment 4 Dmitry Tantsur 2019-01-04 15:18:39 UTC
Code complete. Can be enabled via modifying IronicEnabledDeployInterfaces. Should probably be enabled by default when leaving TechPreview.
