Manage a Cluster

Select a cluster from the list to open its Overview page. This page shows the cluster status, machine groups, add-ons, administrators, network ranges, Kubernetes version, and control-plane component health in one place.

• Pending or Creating: the resource is waiting or being provisioned.
• Updating: the requested change is being applied.
• Ready: the resource is operational. Check machine groups and add-ons separately because they may not be ready yet or may have errors.
• Paused or Suspended: reconciliation or user operations are limited. Resume the resource, or contact support if the panel does not provide a recovery action.
• Error: creation or updating failed. Before trying again, investigate the cause on the affected resource.
• Deleting: the cluster is being deleted.
• Unknown: the panel cannot currently determine the infrastructure status. Wait briefly; if it continues, provide support with the cluster name, project, and time observed.

Under Cluster settings, you can:

• choose an available newer Kubernetes version;
• choose one of the available Cilium versions;
• add or remove administrators and administrator groups.

The name, Pod and Service CIDRs, subnet, and security group are shown for reference only and cannot be changed after creation. Changes can only be saved while the cluster is Ready or Updating.

Administrative access grants broad control over the cluster. Removing a user or group changes KaaS-managed access, but it does not review Credentials or RoleBindings created separately in Kubernetes.

An upgrade indicator appears when a new compatible version is available. Upgrade the cluster control plane first, wait for its status to return to Ready, and then upgrade machine groups that are on older versions.

Before upgrading a production environment:

• read the release notes for the offered versions;
• back up application data and configuration;
• check compatibility, PodDisruptionBudgets, and available quota;
• monitor the cluster and groups until they return to Ready.

Downgrading is not possible. Do not disrupt an upgrade with deletion or repeated edits.

Select Delete cluster from the cluster menu. Deletion cannot be undone. The confirmation includes Delete all volumes associated with this cluster, which is selected by default:

• when selected, associated Persistent Volumes are permanently deleted;
• when cleared, the cluster is deleted without deleting its Volumes. The user can later remove retained disks from Infrastructure → Detachable disks.

Before deleting, back up important data, record the required configuration, and check DNS, Load Balancers, and external connections. Volume cleanup cannot be undone. The cluster remains Deleting until cleanup is complete.
