Karmada Dashboard is a general-purpose, web-based control panel for Karmada which is a multi-cluster management project.

You need to have a Karmada installed on Kubernetes(aka.host cluster) and thekarmadactl orkubectl command-line tool must be configured to communicate with your host cluster and Karmada control plane.

If you don't already have the Karmada, you can launch one by following thistutorial.

In the following steps, we are going to install Karmada Dashboard on thehost cluster where running the Karmadacontrol plane components. We assume that Karmada was installed in namespacekarmada-system and Karmada config islocated at$HOME/.kube/karmada.config, if this differs from your environment, please modify the following commandsaccordingly.

1. Switch user-context of your Karmada config tokarmada-host.

export KUBECONFIG="$HOME/.kube/karmada.config"kubectl config use-context karmada-host

Now, you should be able to see Karmada control plane components by following command:

kubectl get deployments.apps -n karmada-system

If everything works fine, you will get similar messages as following:

NAME                                  READY   UP-TO-DATE   AVAILABLE   AGEkarmada-aggregated-apiserver          2/2     2            2           3dkarmada-apiserver                     1/1     1            1           3dkarmada-controller-manager            1/1     1            1           3dkarmada-kube-controller-manager       1/1     1            1           3dkarmada-scheduler                     2/2     2            2           3dkarmada-webhook                       2/2     2            2           3d

2. Deploy Karmada Dashboard

Clone this repo to your machine:

git clone https://github.com/karmada-io/dashboard.git

Change to the dashboard directory:

cd dashboard

Create the secret based on your Karmada config, the Karmada Dashboard will use this config to talk to the Karmada API server.

kubectl create secret generic kubeconfig --from-file=kubeconfig=$HOME/.kube/karmada.config -n karmada-system

Deploy Karmada Dashboard:

kubectl apply -k artifacts/overlays/nodeport-mode

This will deploy two components inkarmada-system namespace:

kubectl get deployments.apps -n karmada-system                                                                                                                karmada-dev-linux-renhongcai: Fri Jan 10 16:08:38 2025NAME                                  READY   UP-TO-DATE   AVAILABLE   AGEkarmada-dashboard-api                 1/1     1            1           2mkarmada-dashboard-web                 1/1     1            1           2m...

Then you will be able to access the Karmada Dashboard byhttp://your-karmada-host:32000.Note that, the Karmada Dashboard service type isNodePort, this exposes the dashboard on a specific port on each nodeof yourhost cluster, allowing you to access it via any node's IP address and that port.

You also can usekubectl port-forward to forward a local port to the Dashboard's backend pod:

kubectl port-forward -n karmada-system services/karmada-dashboard-web --address 0.0.0.0 8000:8000

Then you can access it viahttp://localhost:8000.

You still need the jwt token to login to the dashboard.

3. Create Service Account

switch user-context to karmada-apiserver:

kubectl config use-context karmada-apiserver

Create Service Account:

kubectl apply -f artifacts/dashboard/karmada-dashboard-sa.yaml

4. Get jwt token

Execute the following code to get the jwt token:

kubectl -n karmada-system get secret/karmada-dashboard-secret -o go-template="{{.data.token | base64decode}}"

it should print results like this:
