Now it breaks the kolla's master branch jobs. And have to remove the "horizon" and "neutron" in the upper-constraints.txt file. check.
i wanna know what's the correct way to install horizon develop branch with upper-constraints.txt file?  https://review.openstack.org/#/c/549456/4/docker/neutron/neutron-base/ Dockerfile.j2  https://review.openstack.org/#/c/549456/4/docker/horizon/Dockerfile.j2 On Thu, Mar 15, 2018 at 9:28 PM, Doug Hellmann <d...@doughellmann.com> wrote: > Excerpts from Thomas Morin's message of 2018-03-15 10:15:38 +0100: > > Hi Doug, > > > > Doug Hellmann, 2018-03-14 23:42: > > > We keep doing lots of infra-related work to make it "easy" to do > > > when it comes to > > > managing dependencies.
