Maintenance: Upgrade of GWDG Kubernetes service (Rancher) 

Time: Thursday 23.06.2022 5:00pm – 7:00 pm.
Affected:  Users of Rancher
Impact: Rancher GUI will be down and Rancher CLI won’t work. The Kubernetes CLI (kubectl) and the hosted Kubernetes clusters not affected by the upgrade and will still work.
On Thursday 23.06.2022, maintenance work on the Rancher application will be carried out within the maintenance window from 5 pm to 7 pm. The objective is to upgrade Rancher from current version 2.5.11 to the new version 2.6.5.
In Rancher 2.6, the old monitoring system, which was deprecated in Rancher 2.5, is now removed. The monitoring system for all the hosted clusters has already been migrated to the new version.
After upgrading, the users will be automatically logged out of the old Rancher GUI and must log in again to access Rancher and the new GUI.
