From f5993cdff9c9d873966d24e7987094fee4d13f0d Mon Sep 17 00:00:00 2001 From: tringuyen Date: Wed, 1 Apr 2020 17:51:06 +0000 Subject: [COMMON] add pre upgrade script for mariadb-galera When upgrading from a version to another, it may be impossible to do it "simply" because of changes in immutable properties of statefulsets. We change that here by creating a temporary deployment which will hold the whole databases during the time the old statefulset gets destroyed and the new one gets created.
