MaksIT.ClusterConsole

MaksIT Cluster Console (also ClusterConsole, MaksIT.ClusterConsole) is an open-source Kubernetes GUI — a native desktop client for Windows, Linux, and macOS. It is an operator console: browse the Kubernetes API, apply YAML, follow a live table, read pod logs, open an interactive shell, port-forward to localhost, and inspect Helm releases and Dapr components already in the cluster. Several kubeconfig contexts can stay connected at once.

It is a Kubernetes desktop app, not a web dashboard and not a command-line client. Cluster access uses the official Kubernetes .NET client, your kubeconfig, and the same RBAC as any other API client. The kubeconfig file on disk is the source of truth. Clicking a catalog row connects that context in this app. The radio beside it only writes kubectl current-context, so the command line can follow. This app does not read that field.

Features

Cluster overview

Click a catalog row to open that context. A green dot is a live session in this app. The radio only writes kubectl current-context for the command line; this app does not follow it. Overview shows CPU, memory, and pod counts from metrics-server; Resource limits can patch container CPU/MEM against node capacity. Cluster and Nodes switch those charts. Errors and Warnings list node, pod, and event problems, a LoadBalancer Service that is Pending or Unreachable, and a PersistentVolumeClaim that is Pending.

Applications

One row per app.kubernetes.io/instance (or name) and namespace. CPU is percent of cluster allocatable; memory is summed from owned pods when metrics-server is available.

Pods

Ready, Restarts, Status, Node, CPU, and Memory. Filters and sort persist per cluster. The open table follows the API watch. Details: Overview, YAML, Events, Logs (Follow), Terminal (interactive shell). Container picks which container logs, the shell, Attach, and Debug use. Attach follows that container's output. Debug adds an ephemeral container beside it; the image box defaults to busybox:1.36. Kubernetes leaves that container on the running pod. It is gone when the pod is recreated. Force delete uses grace period 0 and strips finalizers.

Chat

Settings → AI turns Chat on. The endpoint and model are any local Ollama model you already pulled. The default is qwen3:8b. Reading the cluster is enough with that model. Repairs work better with a larger one: qwen3:14b, qwen3:32b, or qwen3-coder:30b. Put that name in the model box after ollama pull.

Read-only tools are cluster issues, object YAML, logs, and events. Allow the assistant to change the cluster adds restart, pod delete (not force-delete), scale, and YAML apply. Each of those waits for Approve or Reject in the chat. Reject leaves the cluster unchanged. No cloud AI API.

Volume files

Browse, edit, download, and upload files on a PersistentVolume or claim. Double-click a PV/PVC row, or use Browse files on the selected row.

Dapr

First-class navigator: Components, Configurations, Subscriptions, Resiliency, HTTP Endpoints, Sidecars, Control plane.

Port forwarding

Network → Port Forwarding: tunnels persist, restore on reconnect, and retarget a running pod. Double-click Active opens http://127.0.0.1:{port}/. Rebind changes the local port.

Connections

Connections… adds a context to the kubeconfig (bearer token, client certificate, pasted k3s certificate data, or username and password), connects one, or deletes one. Delete can also drop a cluster or user entry that nothing else references. A radio on the catalog, or in that window, writes kubectl current-context for the command line. This app ignores that field and uses the row you click. A green dot is a live session here. Several contexts stay connected until you disconnect them, while kubectl still has one current context. Reload kubeconfig rereads the file.

Navigator

Cluster, Nodes, Applications, Workloads, Config, Network, Storage, Namespaces, Events, Helm, Dapr, Access Control, Custom Resources. Longhorn (volumes and nodes) and CloudNativePG (phase, ready instances, current primary) appear when those APIs are installed. Built-in kinds include admission policies, CSR, CSI objects, API services, flow control, and dynamic resource allocation, plus any CRD installed in the cluster.

Tables

Search filters rows already loaded. Label selector is sent with the list (app=api). The open table watches the API. Column filters and sort stay on this machine, per cluster. Copy includes the column header. Hint explains the kind on screen. Extended selection (Shift or Ctrl) plus a footer action that can run on its own applies to every selected row: Restart, Scale, Delete, Force delete, Force delete namespace, Cordon, Uncordon, Drain, Trigger, and Stop.

YAML

View, server-side apply, create, and delete. New starts an empty document for a kind you can create. Apply falls back to create or replace when the API server rejects an apply patch. JSON and YAML highlighting follows the document. ConfigMap and Secret values use the key name (.json, .yaml, .yml) or stay plain.

Workloads

The Workloads section opens on counts for Pods, Deployments, StatefulSets, DaemonSets, ReplicaSets, Jobs, CronJobs, and ReplicationControllers. A tile opens that table. Scale applies to a Deployment, StatefulSet, ReplicaSet, or ReplicationController. Restart applies to a Deployment, StatefulSet, or DaemonSet. Pause, resume, history, and undo are on a Deployment. A workload's Pod picker chooses which pod Logs and Terminal follow. Trigger starts a Job from a CronJob. Force delete namespace removes the selected namespace, except default, kube-system, kube-public, and kube-node-lease.

Nodes

Cordon refuses new pods. Uncordon accepts them again. Drain asks first. The dialog is a table: Node, Outcome (teal Will move, amber Will remain), Namespace, Pod, and Reason. Will remain covers a DaemonSet, a mirror pod, a completed pod, a pod with no controller, and any pod a PodDisruptionBudget would refuse. Long text wraps and the row grows. Cancel or Escape leaves the node as it is. Drain cordons the node and evicts only Will move. A refused eviction is not deleted. The Images tab marks cached images Used or Unused from the pods on that node.

Config

ConfigMaps and Secrets have a Data tab: keys, a decoded preview, a binary flag, Add key, and Apply data. Secret values are saved back as stringData. The same tables cover resource quotas, limit ranges, HorizontalPodAutoscalers, PodDisruptionBudgets, leases, runtime classes, webhooks, and admission policies.

Network

A Service Status is Active when a load-balancer address is assigned, Pending when none is set, and Unreachable when a requested or BGP address is not the one the cluster reports. The navigator also lists Endpoints, EndpointSlices, Ingresses, NetworkPolicies, and IP addresses.

Storage

Resize a PersistentVolumeClaim. Reclaim changes Delete or Retain on a storage class and its volumes. Changing the class itself is delete-and-recreate; the dialog explains the gap for new claims. CSI drivers, nodes, storage capacities, and volume attachments are in the navigator when the API has them.

Access

Approve or deny a certificate signing request. Token creates a ServiceAccount token and shows it once. Roles, RoleBindings, ClusterRoles, ClusterRoleBindings, and ClusterTrustBundles are editable YAML like any other kind.

Custom resources

Extra columns from the CRD additionalPrinterColumns.

Helm

Charts lists each chart version installed in the cluster, taken from Helm release secrets, with the releases that use it. A release shows every stored revision, the user-supplied values, the rendered manifest, and a diff between two revisions. Chart install and upgrade stay on the Helm CLI.

Metrics

CPU and memory when the metrics API is available. Charts use the same metrics-server data as kubectl top.

Help

Hint on a table explains that kind. Help → Logs shows the app log and crash reports. An unhandled error opens a window you can copy instead of closing the app. Help → About shows the product, license, and contact. After an upgrade, What's New lists additions since the version you last opened.

Requirements

• A kubeconfig (KUBECONFIG or ~/.kube/config) with permission to the target cluster
• Windows, Linux, or macOS
• Optional: local Ollama for Chat (ollama pull qwen3:8b, or a larger model such as qwen3:14b when the assistant may change the cluster)
• From source: .NET 10 SDK

Getting started

Install a build from Releases, or from src/:

cd src
dotnet build MaksIT.ClusterConsole.slnx
dotnet run --project MaksIT.ClusterConsole.UI

Connect a context from the catalog, pick a navigator item, then use the table, details pane, and footer actions.

Linux (Flatpak)

GitHub releases include maksit-cluster-console-{version}.flatpak.

User (this account only):

flatpak install --user ./maksit-cluster-console-{version}.flatpak
flatpak run com.maks_it.clusterconsole

System (all users):

sudo flatpak install --system ./maksit-cluster-console-{version}.flatpak
flatpak run com.maks_it.clusterconsole

Uninstall: flatpak uninstall --user com.maks_it.clusterconsole or sudo flatpak uninstall --system com.maks_it.clusterconsole.

The previous id com.maks_it.ClusterConsole is replaced by this lowercase id. Uninstall the old app before installing the new bundle if it was installed.

If GNOME or KDE does not show a launcher icon, flatpak run may warn that /var/lib/flatpak/exports/share and ~/.local/share/flatpak/exports/share are not on XDG_DATA_DIRS. Log out and back in once so the session picks up those paths.

Linux uses X11/XWayland (Avalonia native Wayland still hangs on GNOME). The sandbox grants --filesystem=home for kubeconfig (~/.kube). AppStream and the desktop file live in data/.

Configuration

Operator layout, open clusters, port-forwards, and Chat settings are stored in MaksIT/Cluster Console/settings.json under the OS application-data folder (%AppData% on Windows, ~/.config on Linux, ~/Library/Application Support on macOS).

Key	Role
AiEnabled	Chat tab. Off until enabled under Settings → AI
AiAgentEnabled	With chat on, restart, pod delete, scale, and apply run only after you approve each one
OllamaEndpoint	Local Ollama API, default http://127.0.0.1:11434
OllamaModel	Local Ollama model, default qwen3:8b. A larger model (qwen3:14b, qwen3:32b, qwen3-coder:30b) is a better fit once changes are allowed
PortForwards	Enabled localhost forwards; restored on reconnect
Layout	Window, panes, last navigator item, per-cluster tables

Chat stays read-only until Allow the assistant to change the cluster is on. Those changes still wait for Approve. The model box accepts any local Ollama model; larger models handle restart, scale, delete, and apply more reliably than qwen3:8b.

FAQ

Is MaksIT Cluster Console a Kubernetes GUI?
Yes. It is a native desktop Kubernetes GUI (operator console) for Windows, Linux, and macOS.

Does it use kubeconfig?
Yes. KUBECONFIG or ~/.kube/config. RBAC is whatever that identity already has. Clicking a catalog row connects that context in this app. The radio only writes kubectl current-context so your command line can use the same cluster. This app does not read that field.

Does Chat send cluster data to a cloud AI?
No. Chat is optional Ollama on the same machine. The model is whatever you set under Settings → AI. By default the tools only read issues, YAML, logs, and events. Turn on Allow the assistant to change the cluster and the same chat can restart, delete a pod, scale, or apply YAML, each after you approve it. A larger local model is the better choice for that.

Can it install a cluster, Helm charts, or Dapr?
No. It talks to an existing Kubernetes API. Helm and Dapr screens list objects that are already there.

Where are the installers?
GitHub Releases.

Tests

utils\Invoke-TestEngine.bat

Or dotnet test MaksIT.ClusterConsole.Tests from src/. Tests use kubeconfig fixtures and do not need a live cluster.

Scope

Desktop operator console for the Kubernetes API. Not a CLI, cluster installer, GitOps, or secret-management system. Helm and Dapr views list objects in the cluster; they do not install charts or administer Dapr building blocks.
