Was out last week, so still catching up on some of this. Thanks Anita
for stirring the pot.
I've got a POC approach proposed in the following 3 patches to do
partial testing in multinode via a post-stack.sh script in grenade (a
way to tell grenade to do another thing after the base stack call is done).
The grenade change - https://review.openstack.org/#/c/199073/
The devstack-gate change that would put subnode setup into post-stack.sh
And the project-config change to make this experimental on devstack-gate
and grenade is here - https://review.openstack.org/#/c/199103/
The first job I created here was a nova-net one, because I know enough
about the paths, and the partial upgrade story on nova (which has been
voting for a year), to know that all bugs introduced here are probably
my own. But if we can get that working, and the nova partial job moved
over, I think expanding it to arbitrary configs is probably pretty simple.
Assistance ploughing through on this direction would be appreciated.
