Pin Octavia containers to run Centos 8 Stream-based containers even on CentOS 7 hosts (!109) · Merge requests · Research Computing Services / Platforms / Cloud Services / arcus-kayobe-config

Paul Browne requested to merge pin_octavia_centos8_stream into arcus/train-staging Jul 11, 2022

Currently we have a mixed control plane of 1 C7 host and 2 C8S hosts, which seems to be causing issues with Octavia container communications indicative of Python2 vs Python3 mismatch.

This change forces C8S containers to run on C7 hosts, so that Octavia is using the same container images eveywhere in the control plane
