Hi openstack-dev,

I have a simple question: why are there no mechanisms to prevent
kolla-build from building images that are known not to work for a
given base/type ?
In the Kolla CI gate, we build everything -- and then, if there are
errors, we match them against a list of images that are known to fail
[1].

This feels backwards, why even build things that are known to fail in
the first place ?

For example, if I do "kolla-build -b centos -t binary", it should not
even attempt to build "bifrost-base" because there's no support for
that distro/type combination.
As an end user and not a CI system using tox, I don't know what is
supported and what isn't.

Are those reasonable expectations ? How hard would it be to implement this ?
