This fix involves an upgrade of Kubernetes and some add-ons. See https://documentation.suse.com/suse-caasp/4.2/html/caasp-admin/_cluste r_upd ates.html#_updating_kubernetes_components for the upgrade procedure.

== Skuba & helm/helm3

In order to update skuba and helm or helm 3, you need to update the management workstation. See detailed instructions at https://documentation.suse.com/suse-caasp/4.2/html/caasp-admin/_cluste r_upd ates.html#_update_management_workstation

documentation at https://documentation.suse.com/suse-caasp/4.2/html/caasp-admin/_miscel laneo us.html#_configuring_kubelet

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
