Kubernetes Clusters Overview

The Overview tab is your operational summary for a cluster. It combines cluster identity, health, capacity, integrations, and networking in a single page.

General

The General panel shows core cluster metadata:

  • Location: provider region for the cluster.
  • High Availability: whether control plane HA is enabled.
  • API Endpoint: Kubernetes API server address.
  • Access:
    • Kubeconfig state (download, downloaded, or revoked).
    • SSH Key state (download or downloaded).

Ingress Endpoints (when available)

When ingress-nginx is installed and has load balancer IPs, an Ingress Endpoints panel appears with IPv4/IPv6 addresses and quick copy actions.

Capacity & Health

This section is the live resource and node health snapshot:

  • CPU: allocatable, usage, requests, limits.
  • Memory: allocatable, usage, requests, limits.
  • Pods: healthy/running/completed status.
  • Node summary:
    • Control Plane count
    • Nodes count
    • Node Pools count
    • Total Nodes
    • Not Ready nodes
  • Refresh: manual refresh and last-updated timestamp.

If detailed node metrics are not yet available, Overview falls back to estimated capacity values.

K3s Signals

K3s Signals surfaces control plane health indicators:

  • Certificate expiry (critical/warning windows).
  • Snapshot health (successful vs failed etcd snapshots).
  • ETCD + API signals (leader status, inflight requests, 5xx rate, etcd request latency).

When signals cannot be collected, the panel shows a metrics availability state.

Node Details

The Node Details section is collapsible and includes:

  • Ready node ratio and pod health summary.
  • Separate groups for Control Plane and Worker nodes.
  • Per-node expandable details (resources and pod status).
  • Quick controls to Expand all or Collapse all.

Kubernetes panel

The Kubernetes card summarizes runtime configuration:

  • K3s version
  • OS image
  • CNI
  • CNI encryption (On/Off)
  • Secrets encryption (On/Off)

It also shows integration status:

  • GitOps (configured repo or not configured)
  • Registry (connected registry or not configured)

Deployments panel

The Deployments card lists recent deployments for the cluster, including name and status for quick health checks.

Add-ons panel

The Add-ons card shows installed add-ons and versions so you can quickly verify platform capabilities on that cluster.

Networking panel

The Networking card provides:

  • Network capability badges: IPv4, IPv6, Private, Host Firewall.
  • Network details such as:
    • Private subnet (if enabled)
    • SSH allowed CIDRs
    • API allowed CIDRs
    • Host firewall state (Cilium)
