upgrades: heat-agent package conflict on upgrade

[James Slagle]

See http://logs.openstack.org/61/451361/1/check/gate-tripleo-ci-centos-7-multinode-upgrades-nv/077b395/

During the upgrade attempt, the heat-agent packages can't be yum updated:

here's the error not line wrapped, which is easier to read:
http://paste.openstack.org/show/604704/

[James Slagle (james-slagle)]

it seems this is caused by 2 issues. both ocata and master from upstream heat-agents are tagged 1.0.0. So, an ocata release would win over master if it happened after.

also, since we are updating to current-tripleo, if we haven't promoted in a while (as is the case now, ocata could be "newer" than master based on version).

sounds like we need pre-release tags on heat-agents, dlrn to build that tag, and then a promotion so we test upgrading to a repo with that build.

[Alfredo Moralejo (amoralej)]

Version tag in openstack/heat-agents problem is 1.0.0 both in master and stable/ocata. Built in ocata promoted repo is newer (20170321004516) that the one in promoted master (20170306124536). Initially subpackages are installed from ocata repo as expected:

Then master repo is configured and it tries to install package openstack-heat-agents which was not installed as part of ocata deployment (maybe, http://git.openstack.org/cgit/openstack/tripleo-heat-templates/tree/environments/major-upgrade-composable-steps.yaml). It tries to install it but version in master is seen as older that the one in ocata so it fails.

The recommended fix is to push a pre-release tag 1.1.0 in heat-agents repo. Currently we need to wait for new promotion in master to get a newer build.

[Steve Baker (steve-stevebaker)]

Installing openstack-heat-agents and python-heat-agent-* will have exactly the same effect (openstack-heat-agents does nothing except depend on all python-heat-agent-*)

I would recommend removing this line from the upgrade script

  yum install -y openstack-heat-agents

Fix proposed to branch: master
Review: https://review.openstack.org/451588

[Alfredo Moralejo (amoralej)]

Note that while that patch may fix the error when installing openstack-heat-agents, the effective result will be that after the upgrade to master we'll have the python-heat-agent-* packages from ocata instead of master, what i guess it's not the desired behavior and could be problematic also. The right solution is to push new tag in heat-agents, IMO.

    Do not install openstack-heat-agents

    Installing openstack-heat-agents is unnecessary since it has the same
    effect as installing python-heat-agent-* which happens on the next
    line.

    Installing openstack-heat-agents is causing issues when mixing ocata
    and master repos, since there hasn't been a release on master since
    ocata was branched.

I'll do a heat-agents release soon

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/tripleo-heat-templates 7.0.0.0b1 development milestone.
