Hi all!
While people are enjoying the Forum, I also have something to show.
I've got a lot of questions about auto-discovery, so I've recorded a demo
of it using TripleO Ocata: https://www.youtube.com/watch?v=wJkDxxjL3NQ.
Please let me know what you think!
Dmitry

Hi, thanks for interesting demo! I am wondering how does this compare to
"Discover nodes, knowing IP range for their BMCs and the default IPMI
credentials" blueprint [1].
These are essentially unrelated approaches to doing node discovery.
I really like the power of introspection rules. TripleO UI can nicely benefit
from this, letting user provide rules to apply on introspection.
Regarding the autodiscovery use case, is it possible to somehow power up the
machines using API? What if user does not know the $IPMI_HOST?
Well, this particular use case is about manual or not supported power. E.g. you
press the button or you use some fancy proprietary CMDB.
Can we replace enabling autodiscovery option in undercloud with discovering
nodes as defined in [1] which would return json resembling to instackenv.json
file and register the nodes using this? Does it make sense?
Why replace, if we can have both? :)
Can Ironic-inspector send messages via zaqar to notify subscribers about
starting the autodiscovery?
This is a good idea, and Ironic is essentially capable of it (as soon as you set
up Zaqar to listen to oslo.messaging topic). Inspector is not, that would be a
good RFE.
