I sure do! That's partially what led me to looking at scheduler hints (more
below).
There were two issues, actually.
1. At first, I could not prove that it was actually working ... but then I
figured it out:
outputs:
host:
description: The host this server lives on.
value: {get_attr: [my_server, show, 'OS-EXT-SRV-ATTR:host']}
2. After some discussion elsewhere, it was suggested that a scheduler hint
might be a better option.
More importantly, it may also be the case (again, for my particular situation)
that the Heat template author/generator is blind to the notion of availability
zones. It only knows about hosts. Thus, I don't want to depend on az:host
notation if I can help it.
When I learned that I can set up single-host Host Aggregates with metadata of
the form host=myhost, I started following that path ... and here I am!
