Cluster Actions
Cluster-level lifecycle actions are available from the cluster details page header and from the three-dot Actions menu on each row of the Kubernetes list. Most actions require the cluster to be Running and the appropriate update or delete permission on your project.
| Action | Available when | Section |
|---|---|---|
| Add Node Pool | Running; update permission | Add Node Pool |
| Upgrade Master Plan | Running; sufficient credits | Upgrade Master Plan |
| Add LB IP | Running; update permission | Add LB IP |
| Convert to Committed | Running; eligible plan; not already committed | Convert to Committed |
| Committed Cluster Settings | Running; cluster is on a committed plan | Committed Cluster Settings |
| Delete | Running; delete permission | Delete Cluster |
Add Node Pool
The drawer uses the same options as the create flow: pool name, plan/family, and pool type - Static (fixed node count) or an autoscale strategy (elastic, scheduled, or both) with its scaling policy.
A cluster can have up to 10 node pools. A newly added pool appears at the top of the list and takes a few minutes to deploy. For the full field reference and per-pool controls, see Node Pools.
Upgrade Master Plan
Upgrading the master plan increases the resources allocated to the cluster's master (control plane) node, so it can handle heavier control-plane workloads. Use it when control-plane usage grows.
Preconditions
- The cluster must be in the Running (Active) state.
- You must have enough credits to cover the upgrade.
Steps
- From the cluster list or details header, select Upgrade Kubernetes Master Plan.
- Review the available upgrade plans - only higher-tier plans from the same series are shown.
- Select the plan and choose Upgrade.
- Select the confirmation checkbox.
- Confirm the upgrade.
Plan Selection Rules
- Higher tier only. Only plans above your current master plan are offered.
- No downgrade. You cannot select a plan lower than the current tier.
- Same series. Upgrade candidates are restricted to the same plan series as your current plan.
- Committed matching. If your current master plan is committed, only plans with a compatible commitment/term are eligible.
Restrictions
- The upgrade is disabled while the cluster is Creating or Terminating.
- The upgrade is blocked when you have insufficient credits.
- Upgrading the master can cause brief control-plane unavailability while the node is resized; the cluster shows Upgrading Master during the operation.
Add LB IP
Reserve an external load-balancer (Service) IP for the cluster. Selecting Add LB IP (requires update permission and the Running state) opens the cluster on its LB IP Pool tab, where you reserve and attach the IP used by Kubernetes services of type LoadBalancer.
For the reservation steps and how the IP is consumed by your workloads, see Networking.
Convert to Committed
Convert the cluster's hourly nodes to a committed plan for a lower effective rate. The option appears for eligible (non-private) clusters that are not already committed, and requires the cluster to be Running. Choose the committed plan to apply, then confirm. See Committed Plans.
Node pools can also be converted individually from the Node Pool tab.
Committed Cluster Settings
For a cluster already on a committed plan, Committed Cluster Settings controls what happens when the committed term ends:
- Auto-renew the committed plan - renew the same committed plan.
- Switch to hourly billing - fall back to the standard hourly rate.
These settings take effect only after the current committed period ends. The option is shown for committed (non-private) clusters that are Running.
Delete Cluster
Deleting a cluster permanently removes all associated data and resources - nodes, volumes, and configurations. This cannot be undone.
- Select Delete from the cluster header or row actions (requires delete permission and the Running state).
- Confirm in the dialog.
The cluster moves to Terminating and is removed when complete. A cluster in the Terminating state cannot be opened or acted on.
