keycloak migrate to heu20, upgrade, DB migration to PostGres
After talking to @armin.felder and in order to reduce fairlogin downtime when upgrading the database server heu13 @indigoxela https://git.fairkom.net/hosting/DevOps/-/issues/254 we suggest:
- install up to date keycloak in docker or crio on heu20 with postgres @jbuechele (your new ssh key is there)
- import config from heu16 keycloak and compare/check all settings
- export keycloak DB as XML and import on heu20
- test
- switch domain id.fairkom.net (already points to heu20) to heu20 nginx in
/etc/sniproxy.conf
on heu20 @roland.alton - PostGres database backup cron job (incremental to
/var/backups
)
Earlier upgrades went smooth #85 (closed) #48 (closed) (on same VM, though).
