Next Tuesday evening, we will upgrade the Rancher Management Service as well as the underlying Kubernetes cluster. The managed Kubernetes clusters are NOT part of this maintenance.
Date: Tuesday, 2021-05-11 Time: Starting 22:00 CEST (UTC+02:00)
During the maintenance procedure, various parts of the Rancher Management Service will be restarted, which can lead to short downtimes of the management console (Web GUI, kubectl API via rancher.vshn.net). Workloads on managed Kubernetes clusters are not affected.
After the procedure, Rancher will upgrade the on-cluster components of all managed clusters. This can lead to downtimes of the management of managed clusters as well as managed components (monitoring/metrics, aggregated logging).
