Troubleshooting 'No Endpoints Available for Service 'Kubernetes-Dashboard'' Error

Troubleshooting “No Endpoints Available for Service ‘Kubernetes-Dashboard’” Error

If you’re a data scientist working with Kubernetes, you’ve likely encountered the error message: “No endpoints available for service ‘kubernetes-dashboard’”. This error can be frustrating, especially when you’re trying to monitor your cluster’s performance or debug issues. In this blog post, we’ll walk you through the steps to troubleshoot and resolve this common issue.

Understanding the Issue

Before we dive into the solution, let’s understand the problem. Kubernetes Dashboard is a general-purpose web-based UI for Kubernetes clusters. It allows users to manage and troubleshoot applications running in the cluster. The error “No endpoints available for service ‘kubernetes-dashboard’” typically occurs when the Kubernetes Dashboard service is not running or not correctly configured.

Step 1: Check the Status of the Kubernetes Dashboard

The first step in troubleshooting this issue is to check the status of the Kubernetes Dashboard. You can do this by running the following command:

kubectl get pods --namespace=kubernetes-dashboard

This command will list all the pods running in the ‘kubernetes-dashboard’ namespace. If the Kubernetes Dashboard is running correctly, you should see a pod with a name starting with ‘kubernetes-dashboard-’ and a status of ‘Running’.

Step 2: Verify the Service Configuration

If the Kubernetes Dashboard pod is running correctly, the next step is to verify the service configuration. You can do this by running the following command:

kubectl get service kubernetes-dashboard --namespace=kubernetes-dashboard

This command will display the configuration of the Kubernetes Dashboard service. Make sure that the ‘Selector’ field matches the labels of the Kubernetes Dashboard pod.

Step 3: Check the Service Endpoints

If the service configuration is correct, the next step is to check the service endpoints. You can do this by running the following command:

kubectl get endpoints kubernetes-dashboard --namespace=kubernetes-dashboard

This command will display the endpoints of the Kubernetes Dashboard service. If the service has no endpoints, it means that the service is not able to connect to the Kubernetes Dashboard pod.

Step 4: Troubleshoot the Issue

If the Kubernetes Dashboard service has no endpoints, there are several possible causes:

• The Kubernetes Dashboard pod is not running: In this case, you can try to restart the pod.
• The service configuration is incorrect: In this case, you can try to correct the service configuration.
• There is a network issue: In this case, you can try to troubleshoot the network issue.

Step 5: Restart the Kubernetes Dashboard

If the Kubernetes Dashboard pod is not running or if there is a problem with the service configuration, you can try to restart the Kubernetes Dashboard by running the following commands:

kubectl delete service kubernetes-dashboard --namespace=kubernetes-dashboard
kubectl delete deployment kubernetes-dashboard --namespace=kubernetes-dashboard
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

These commands will delete the existing Kubernetes Dashboard service and deployment and create a new one.

Conclusion

The “No endpoints available for service ‘kubernetes-dashboard’” error can be a roadblock when managing your Kubernetes cluster. However, by following these steps, you should be able to troubleshoot and resolve this issue. Remember, the key is to check the status of the Kubernetes Dashboard, verify the service configuration, check the service endpoints, and if necessary, restart the Kubernetes Dashboard.
