To anyone on the cloud SIG team, specifically dealing with a TripleO deployment: As of this week, a stock install of the "Ussuri" and "Victoria" releases of TripleO undercloud fail due to internal puppet module issues as follows: Note that at least Ussuri worked recently (in the last few weeks): Ussuri: "puppet-user: Error: no parameter named 'key_size' (file: /etc/puppet/modules/tripleo/manifests/certmonger/haproxy.pp, line: 102) on Certmonger_certificate[haproxy-external-cert] (file: /etc/puppet/modules/tripleo/manifests/certmonger/haproxy.pp, line: 102) on node centos8-testing.localdomain" It seams that this may have been fixed in https://github.com/openstack/puppet-tripleo/commit/963b47338008f16039a815b03f00ad6e387b6ca0 Victoria: ... "Could not find class ::neutron::plugins::ml2::ovs_driver" ... I'm not sure if this is related/fixed, but it may be: https://review.opendev.org/c/openstack/puppet-neutron/+/757803 Steps to reproduce: Base install of CentOS8.3 Minimal (VM and baremetal behave the same) install centos-release-openstack-<version> [Optional?] dnf module disable container-tools:rhel8 and dnf module enable container-tools:2.0 dnf install python3-tripleoclient ceph-ansible openstack-selinux dnf distro-sync add the "stack" user and such, add sudo rules, etc. [copy undercloud.conf.sample to undercloud.conf] NOTE: minor customization of IPs in my test environment. [Optional] generate the container parameters yaml openstack undercloud install --verbose Has anybody else experienced this? Any ideas on how to rectify the issue or prevent this from happening in the future. This seems like a pretty big breakage since it is effectively a no-go for any new install at least. (I'd assume the overcloud install will break in the same manner since it should be using the same repos and containers.) Please pardon my ignorance if I'm missing something obvious since I'm a new poster to this thread. Thanks, -Nathan
