From 88c946de1ce8299fa8cda05c537e1f90a4c29512 Mon Sep 17 00:00:00 2001 From: Tim Bielawa Date: Wed, 26 Jul 2017 13:21:18 -0400 Subject: Use existing OPENSHIFT_DEFAULT_REGISTRY setting during masters scaleup Fixes a bug which reported that AFTER a cluster upgrade from OCP 3.5 to 3.6, any masters which are later added via the scaleup playbooks are setting a value for OPENSHIFT_DEFAULT_REGISTRY which is inconsistent with the already configured masters. * OPENSHIFT_DEFAULT_REGISTRY value is saved from oo_first_master * The new scaleup master has a fact set noting it is a scaleup host * The saved OPENSHIFT_DEFAULT_REGISTRY value is used instead of the default for 3.6, which is to use a hard-coded registry value of 'docker-registry.default.svc:5000' Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1469336 --- playbooks/common/openshift-master/config.yml | 55 +++++++++++++++++++++- roles/openshift_master/tasks/systemd_units.yml | 6 +-- .../templates/atomic-openshift-master.j2 | 5 +- .../native-cluster/atomic-openshift-master-api.j2 | 5 +- .../atomic-openshift-master-controllers.j2 | 5 +- roles/openshift_master/vars/main.yml | 1 + 6 files changed, 70 insertions(+), 7 deletions(-) diff --git a/playbooks/common/openshift-master/config.yml b/playbooks/common/openshift-master/config.yml index 5de03951c..b30450def 100644 --- a/playbooks/common/openshift-master/config.yml +++ b/playbooks/common/openshift-master/config.yml @@ -5,6 +5,19 @@ t_oo_option_master_debug_level: "{{ lookup('oo_option', 'openshift_master_debug_level') }}" pre_tasks: + # Per https://bugzilla.redhat.com/show_bug.cgi?id=1469336 + # + # When scaling up a cluster upgraded from OCP <= 3.5, ensure that + # OPENSHIFT_DEFAULT_REGISTRY is present as defined on the existing + # masters, or absent if such is the case. + -
