Rahti maintenance break
Time: Saturday 17.5.2025 (10:00 – 16:00) EEST
As part of our ongoing commitment to maintaining the best performance of Rahti service, we have scheduled a maintenance break on 17.05.25 from 10.00 to 16:00.
During this maintenance break, we will perform major version upgrades to the Rahti cluster, targeting OKD version 4.17/ Kubernetes version 1.30. The following APIs will not be available in version 4.17:
| Resource |
API version |
| flowschemas | flowcontrol.apiserver.k8s.io/v1beta2 |
| prioritylevelconfigurations | flowcontrol.apiserver.k8s.io/v1beta2 |
These upgrades will allow us to adopt the latest OKD releases, which are based on Centos Stream CoreOS (SCOS), in contrast to the previous releases, which were based on Fedora CoreOS (FCOS).
Rahti’s API and console will occasionally be unavailable during the upgrade, and your pods will restart and migrate between different worker nodes.
Thank you for your understanding and cooperation.
If you have any questions or concerns, please do not hesitate to contact our support team at servicedesk@csc.fi.
