Maintenance work on Keycloak and Harbor, scheduled 2 years ago

To update the backend services for Keycloak and Harbor, we need to announce a maintenance work for both services starting at 27.10.2021 20:00 to 21:00. During the update, backend services need to be restarted and thus frontend services may be unavailable for a short time.

Keycloak is used for access control (authentication, authorization) for the Kubernetes API, so access may be limited during the maintenance, especially if new users or tokens need to be created.

Harbor is used for providing the SysEleven Container Registry (https://scr.syseleven.de/), so access may be limited during the maintenance.

There will be no impact on running clusters, however, applying changes to clusters may not be possible if the named services are being used.
